Start Date:

Abstract:

Objectives • To examine Late Cenozoic dikes and tuffs exposed along the Yarlung Tsangpo suture zone in Tibet. • To collect deep crustal xenoliths from within the dikes as a means to sampling the lithosphere under Tibet. • To use knowledge gained from this study to provide fundamental constraints in order to test tectonic models of the India-Asia collision As a result of the past eight years of investigations by the HKU Tibet Research Group along the Yarlung Tsangpo suture zone we are aware of numerous unstudied outcrops of Neogene intrusive and volcanic rocks. Such rocks may be considerably more widespread than realized as previous geochemical studies by other groups have concentrated on rocks that crop out within the immediate vicinity of major access routes across the Tibetan Plateau. Our observations suggest that not only intrusive units are present but that eruptive units also occur at some localities. At some of these localities we have observed lower crustal xenoliths within diatremes and other rapidly emplaced volcanic units. These xenoliths contain a preserved record of the nature of the material that underlies the Tibetan Plateau. We plan to sample and use such xenoliths as a window to the deep crust beneath Tibet.

Project Title:

The significance of unconformities bounding the Linzizhong Formation in southern Tibet

Aitchison JC, Ali JR

Department:

Start Date:

04/2007

 

Abstract:

ObjectivesSimple models for the tectonic evolution of the southern margin of Eurasia assume subduction of Tethyan Ocean lithosphere beneath the southern margin of Eurasia from Late Jurassic until India collided with Asia in the Cenozoic. However, marked unconformities in the stratigraphy of the volcano-sedimentary succession that developed along the southern Lhasa terrane indicate significant changes in tectonic regime during this interval. The presence of such unconformities is consistent with the hypothesis that Tethys was similar to modern-day oceans and contained numerous irregularities such as sea mounts, aseismic ridges and oceanic plateaux. As can be seen from the present Andean subduction system where Pacific crust is subducting under South America (a modern analogue of the Cretaceous-Early Cenozoic southern margin of Eurasia), the arrival of such features at the trench results in marked disruption to volcanic arcs located above the subducting lithosphere.This project will begin a critical examination of unconformities that bound volcano-sedimentary strata, which developed in response to subduction of the Tethyan Ocean beneath Eurasia and aims:o to establish the age and duration of the unconformity between the Takena Formation and Linzizhong volcanics in southern Tibet.o to determine the significance of this unconformity with regard to it's implications for changes in tectonic regimeo to find the youngest Linzizhong volcanics and thereby determine when Indian continental lithosphere entered the subduction zone shutting off volcanism and began to collide with Asiao to check for any diachroneity in the unconformities along regional strikeo to determine the implications of changes in tectonic regime for uplift and development of the Tibetan Plateauo develop an understanding of the nature of the now subducted Tethyan Oceano to determine how the development of these features might have pre-conditioned the lithosphere of southern Eurasia prior to India-Asia collisiono to set the scene for a wider investigation of these, and other, regional uniformities across southern Tibet that will form the basis of a RGC grant applicationKey IssuesDevelopment of the angular unconformity between the Late Cretaceous Takena Formation and overlying latest Cretaceous to Eocene Linzizhong Volcanics in the Lhasa terrane cannot easily be related to any known tectonic event during or leading up to the India-Asia collision. However, available data indicate that this feature records a 15 million period of non-deposition, deformation, uplift and erosion and must therefore mark a significant tectonic event. Likewise the unconformity at the top of the Linzizhong Volcanics marks an important tectonic event, namely onset of the collision between India and Asia yet it is poorly located and not well understood.ProblemsAlthough the distribution of strata assigned to both the Takena, Linzizhong and successor formations is known at a reconnaissance level, the location of bounding unconformities is not precisely known. Because of this we do not know the ages of the youngest strata beneath and above the unconformities nor do we know their duration and significance. Clearly they mark important tectonic events but whether or not these events were rapid and intense or longer and more sustained remain uncertain. In order to develop accurate tectonic models one must establish the nature and significance of hiatuses in the geological record and despite the fact that Tibet provides geologists with their type example of a continent-continent collision system this is yet to be achieved in southern Tibet.

Start Date:

Abstract:

The fundamental objective of the proposed project is to develop new approaches/methods to facilitate recognition, identification, quantification, ranking/weighting, integration and delineation of various general and site-specific factors, which influence occurrence of landslides in time and space. Firstly, managing and preserving the original qualities of a multi-variable and multi-source data set which also show spatial and temporal variability is a significant challenge. Furthermore, some of these data are originally in linguistic form and needs to be quantified and integrated with the originally quantitative data without distorting their original notion. Thirdly, ranking and assigning weights to different factors are probably the weakest links in the susceptibility schemes. In order to tackle the first set of issues, the project should benefit from the data management, layer aggregation and graphical facilities of “geographical information systems”. In addressing the other issues, use of the fuzzy set theory and probabilistic multi-factor analysis together with the conditioning of the data using the well-documented landslides should provide a rigorous conceptual framework.

DURABILITY OF LIMESTONE AS ARMOURSTONE

Start Date:

Abstract:

While certain rock types such as most igneous rocks in fresh states are proven to be best performers when exposed to environmental and loading conditions as constituent materials of hydraulic structures, absence of such rocks necessitate consideration of marginal rock types for such projects. This study is designed to assess the suitability of impure limestone through characterization of its material properties and durability in-service. Limestone is one of the most common types of rocks found worldwide, especially along the coastlines. The ever-increasing demand for good quality (pure and massive) limestone as dimension and face stone in building industry leave only the poor quality limestone to be economical alternatives in armourstone production. However there are potential problems associated with the durability of such rocks. The analysis of historical performance of such rocks along the coastlines together with the characterization of source rocks should provide a significant input to the current understanding of their durability and degradation rates as armourstone. Material characterization including assessment of durability and degradation rates is crucial in geotechnical design, selection of appropriate quarrying (production), development of effective on-site sorting, handling, transport, placement and maintenance procedures, and finally realistic prediction of service-life of hydraulic structures built of rock. Thus this initial study will concentrate on material characterization of marginal (impure, porous, fractured and/or thinly bedded) limestone to determine what controls their past and future performance as armourstone.

Start Date:

Abstract:

The proposed project, if funded, will become part of a four-way collaboration on the neotectonics of Longmenshan Fold and Thrust Belt among Ecole Normale Superieure (ENS) of Paris, France, Chengdu University of Technology (CDUT) and Southwest Petroleum College (SWPC) of Sichuan, China, and The University of Hong Kong (HKU). The Longmenshan (LMS) Mountains forms a topographic front west of Sichuan Basin in China, rising abruptly to an elevation close to 8000m, which points to the existence of deep active tectonic processes driving the uplift of the mountain range. The activity is confirmed by the seismicity in the foreland of the Mountains, with several magnitude>7 earthquakes during the last century. Understanding how such a topography is maintained is of major interest for the understanding of the dynamics of the system. Some recent studies demonstrate that erosion of topography may be balanced by ductile shearing within the deeper part of the crust, which in turn contributes to maintaining the relief in the eroded zones. The collaborative research project aims to acquire a better understanding of the dynamics of the lithosphere through a detailed investigation of the crust structure of a 300-km long transect between the cities of Chengdu and Danba across the mid-section of the Longmenshan Mountain Range. Because of the scale of the study area, determination and interpretation of the crustal structure has to rely on geophysical studies using seismic, magnetic, gravity, and magnetotelluric data. In this collaborative research programme, ENS has obtained funding to carry out a seismic tomographic survey of the transect and CDUT and SWPC have agreed to provide logistical support and to monitor of the seismic stations over a year period. A fundamental problem of geophysical models, however, is the non-uniqueness of the solution obtained from inverse modeling of geophysical data. To overcome such a limitation, geophysicists often use multiple geophysical approaches to study the same profile, and to ensure a consistency in the model obtained by using different geophysical approaches. The primary geophysical means of this particular collaborative project is seismic tomography, which is subject to the same problem of non-unique solution. To provide additional means of checking and calibration, I have proposed to carry out a gravity and magnetic study of the same transect. Specifically, the objectives of the proposed study are (1) to determine the gravity anomaly profile across the transect and to produce through inverse modeling a density model of the profile, and (2) to undertake inverse modeling of aeromagnetic data from the same area to identify the depth of magnetic anomalies. The results will be used to constrain and calibrate the model obtained by the seismic tomographic survey.

Abstract:

(1) Submarine groundwater discharge (SGD) is defined here as all direct discharge of groundwater across the ocean–land interface, including recirculated seawater due to tidal fluctuations and other forcings. The coastal areas are one of the most valuable and vulnerable of Earth's habitats. Because coastal areas are the ultimate discharge zones of groundwater, SGD into the coastal zone has received increased attention in the last few years. SGD is now believed to represent an important pathway for fluid and chemical transport between land and ocean, although it remains a poorly understood phenomenon (Kim and Hwang 2002). The influence of SGD on the environment and the ecology of coastal systems may be more important than previously thought because of the many nutrients and contaminants carried in groundwater. (2) SGD may be particularly important in the China Sea where the surface water input is progressively decreasing due to dam construction on major rivers and extensive river water consumption due to rapid economic growth. The Southeast China Sea has suffered severely from HAB, especially in recent years. Nutrient input directly from river runoff and sewage is recognized a key factor responsible for HAB, but input from SGD into the coastal systems of the China Sea and its impact on HAB have been largely ignored. An important aspect of nutrient input via SGD is the possible difference in N/P ratios supplied by this route compared to surface runoff. The N/P ratio may control the type of organisms that are successful in the coastal water. None of the previous studies in Hong Kong have investigated the role of temporal variations in groundwater quality in the occurrence of HAB. (3) The objective of this project is to investigate systematically and quantitatively the phenomenon of SGD and its environmental and ecological implications with a case study in Tolo Harbour. Specifically, we aim to study: 1) the quality and quantity of SGD and its temporal and spatial variations and 2) possible relationships between SGD and marine water quality and HAB. The project will be carried out by an interdisciplinary research team consisting of hydrogeologist, marine geochemist, ecologist, and radioisotope physicist. (4) Tolo Harbour is selected for this study for the following reasons: 1) it is a site of long-term monitoring of marine water quality, groundwater level and red tides; 2) it has a well-defined catchment of manageable size with relatively large groundwater discharge; 3) there is an abundance of existing geological and hydrogeological data for the area; 4) Various radiochemical and hydrological methods can be applied to estimate SGD in the single harbour and cross checked; 5) SGD is believed to have potential ecological implication such as formation of HAB; 6) We have carried some preliminary investigations and believe that it is an ideal site for our study. (5) The project will be divided into several subtasks: 1) Collection and compilation of existing geological, hydrogeological and chemical data; 2) Field hydrogeological studies accompanied by a one-year program of groundwater and seawater chemical monitoring. The main nutrients such as nitrogen, phosphorus and silicon and micronutrients such as copper, zinc, chromium, iron, and manganese will be analysed and monitored; 3) Estimation of SGD by radium and radon isotope analysis, installation of seepage meters, and hydrological and hydrogeological methods including 3D density-dependent flow with solute transport modeling; SGD estimated from different approaches will be compared and cross-checked carefully since different approaches may estimate different components of SGD. 4) Statistical analysis of time series of seawater quality and groundwater level; 5) Examination of the environmental and ecological roles of SGD in coastal processes such as eutrophication and associated HAB. (6) This project will be the first of its kind in the Southeast China Sea and will provide valuable quantitative information for evaluation of SGD, allowing us to develop a deeper understanding of the interactions between coastal seawater and groundwater via SGD. It will also provide methodology and insight for predicting and evaluating SGD in coastal systems. The findings from this project, which will be published in international journals, will have not only theoretical interest but will be of practical benefit for sustainable use and development of coastal ecosystems in Hong Kong and elsewhere.

Abstract:

(1) The primary objective is to date sediments from Gurbantunggut Desert to provide a chronological framework for the study of paleoenvironmental change in this remote and little-studied area. Alternations of relatively coarse sands, fine sand and sand with high clay content have been reported in Gurbantunggut Desert and it has been suggested that they span the last 150 thousand years. In the southern part of the desert, Holocene paleosols had developed on the top of sections; however, because there is a lack of uncontaminated organic material found within the aeolian deposits for use in a radiocarbon dating study, the chronological framework is poor. Within this project, these sandy deposits will be dated with optically stimulated luminescence dating techniques to provide direct chronological evidence; high-resolution sampling may produce centennial scale information on aeolian activity in this region over tens of thousands of years. (2) The second objective is to study the recent migration of dunes. Understanding recent dune migration is critically important to the success of desertification hazard-prevention projects and environmental conservation in an ecologically-fragile area. The use of a combined study using ground penetrating radar (GPR) and optical stimulated luminescence (OSL) dating will provide information of 4-dimensions (space and time) on recent dune movement in Gurbantunggut Desert. This will be the first time that both techniques have been applied in Chinese desert areas. Recent migration of dunes might be caused by recent cultivation and immigration to the region, activities which have happened only in the last few centuries. (3) The third objective is to reconstruct the paleoenvironment of the region, and identify the similarities and differences of paleoclimate changes in Gurbantunggut desert compared with other deserts in China. The current climate in Gurbantunggut is significantly different from other Chinese deserts. Annual precipitation is only about 100-200 mm, which is significantly lower than other stabilised or semi-stabilised deserts in eastern China. This project will provide a direct comparison with other deserts, e.g. Hulun Buir desert, which have previously been the subject of OSL dating studies. (4) This study will provide direct and detailed chronological evidence for sections from a late Quaternary sequence from an area that is sensitive to climatic change. Information on the direction, timing and sand volume will be provided for dunes that have moved recently. This will be useful in forming strategies and policies on environmental conservation and immigration in an ecologically-fragile part of China.

Abstract:

The Luobusa ophiolite of Tibet appears to contain ultra high pressure minerals which may provide a window into mantle chemistry and structure. We wish to separate these minerals and determine their structures and compositions in great detail in order to determine their conditions of formation. This seed grant is applied for in order to obtain as far as possible a complete collection of UHP and other heavy minerals from the chromitite ores of the ophiolite and the surrounding mantle rocks. Subsequently, we will ascertain whether the minerals also occur in the harzburgitic country rocks as well as in the chromitites in which they have been found to date. This will allow us to test several different models that are envisaged for the formation and capture of the UHP minerals. Finally we will use the mineral properties to provide an overall picture of mantle structure from below the Transition Zone to shallow sub-crustal levels and therefore test models of deep lithosphere subduction and mantle convection.

Abstract:

The Dead Sea Fault System (DSFS) in the western Middle East (Jordan-Israel-Lebanon-Syria-Turkey) is a prime example of a continental transform fault system, marking the juxtaposition of two lithospheric plates. However, it is of particular interest because of its complexity, length, and the occurrence of long lived volcanism on both sides of the fault, unlike other examples such as the San Andreas Fault of California. Why does this volcanism occur and what are the sources of the volcanic rocks? Although there have been a number of studies undertaken, particularly geophysical, geochronological and structural analyses, the geology of the northern segment of the DSFS, especially in terms of petrology and geochemistry of the volcanic rocks, is little understood. In this area, the northwest margin of Arabia, the suture between Arabia and Eurasia is one of the most tectonically active zones in the world, with convergence ongoing at a rate of approximately 18+ 2mm/year in a NNW direction. Extensive alkaline intraplate magmatism of two ages, Mesozoic and Late Cenozoic, has been identified in the region. The Cenozoic magmatism appears to be associated with bends in the DSFS, i.e. perhaps contiguous with transtensional structures and may in fact be of two phases possibly associated with the staggered opening of the Red Sea and the northward propagation of the fault system, firstly in pre-Miocene/Early Miocene time and later in post-Miocene time. One interesting feature is that the total post-Miocene slip in the northern segment of the DSFS is reported as less than 25km, far less than the 45-60 km measured in the south. A possible interpretation is that the folding and thrusting events in the Palmyride Fold Zone in central Syria have accommodated the extra 25-odd km, the resulting structures of which are essential to the accumulation of petroleum resources. The cause of the magmatism is itself debatable. One reason could be that it is related to the rifting of the Red Sea (a slab-pull hypothesis), which presumably started in the south. Another could be that there is mantle plume activity in the area, with the plume head located somewhat to the south, but magmatic activity extending far north along a “leaky” fault zone, and concentrated by transtensional sections of the system . Indeed, to the south, isotopic signatures of the volcanic rocks support plume activity, but such data are not yet available for the rocks to the north of the system. If plume activity is the reason for volcanism, then the questions are, “was (is) this a single long-lived plume or two separate events”, and “is this the same plume as that operating far south in the Afar region or another plume altogether”? Within the Syrian border, carbonates have been recorded either in outcrop or in well logs throughout most of the geological past, indicating that NW Syria has repeatedly shifted between shallow and deep sea environments since the breakup of Gondwana and the opening of Paleo-Tethys, although for the past 100 Ma has steadily shifted from deep sea to continental margin environments, as evidenced by the intercalation of Mesozoic basalts with deep water pelagic limestones, and the eruption of Late Cenozoic basalts on top of shallow water limestones. This change in eruptive environment probably occurred because of tectonic events and isostatic rebound resulting from lithosphere shortening and thickening on collision, as observed in the comprehensive folding and faulting of rocks of the Arabian continental margin. The question then is “have all the basalts been derived in a similar fashion from Late Mesozoic to Recent”? The overall objective of this research project therefore is to build on the preliminary field work using laboratory studies to reveal the petrogenesis of the basalts and their associated nodules. Major emphasis will be placed on the origin of the Pliocene-Holocene basalts and their inclusions, and the Late Mesozoic basalts will be examined for comparison and to examine changes in the nature of volcanism throughout the history of the DSFS. Through a study of the ultramafic inclusions found in the basalts it should be possible to disclose the evolution of the upper mantle (changes in source regions) from the Late Mesozoic to the Late Cenozoic. The problems addressed by this research project are: • the genesis of basaltic rocks along this continental transform fault system • the tectonic evolution of this part of the Eastern Mediterranean in Late Cenozoic time • the condition of the upper mantle in the NW corner of the Arabian lithosphere plate in Late Cenozoic time • the geological evolution of the region from Late Mesozoic to Late Cenozoic, particularly the staged (?) motion along the DSFS

Abstract:

Our current understanding is that the old continental crust formed originally from partial melts derived from the primitive mantle and the remaining residue formed the subcontinental lithospheric mantle. This process resulted in relative depletion of Fe and enrichment of Mg in the lithospheric mantle, leading to a lower density (about 3.0g/cm3) than that of the underneath asthenosphere (about 3.35 g/cm3). This density difference helps explain why most cratonic lithosphere has remained stable after formation and why it behaves as rigid plates in the scheme of global tectonics. The lithospheric mantle underneath ancient cratons in the world is commonly stable after its formation. However, this is not the case for the North China Craton. The thick and cold cratonic lithospheric mantle remained intact throughout the Paleozoic, but had changed to a thin and hot lithospheric mantle with oceanic affinity by the Cenozoic, as manifested by data from mantle xenoliths entrained in Paleozoic kimberlites and in the Cenozoic basalts (e.g. Griffin et al., 1992, 1998; Fan and Menzies, 1992; Menzies et al., 1993; Deng et al., 1994; Fan et al., 2000). This means a dramatic physical and chemical change occurred in the lithospheric mantle underneath the NCC sometime during the Mesozoic. The behavior of this craton is remarkably different from its counterparts elsewhere in the world and contradicts our previous understanding of lithospheric evolution. Therefore, it is important to understand the cause of the thinning event, the process and timing of the transformation, the mechanism of the replacement and the overall geodynamic environment in which it occurred. Because this is an interesting and important scientific problem, it has been a major research topic in the last decade, and important progress has been made in understanding this event (e.g. Menzies and Xu, 1998; Xu et al., 1998; Zheng and Lu, 1999; Xu, 2001; Zheng et al. 2001; O'Reilly et al., 2001; Gao et al., 2002; Zhang et al., 2002, 2003, 2004; Wilde et al., 2003; Deng et al., 2004). Much of the data used in these investigations came from mantle xenoliths in Cenozoic and Mesozoic volcanic rocks. The investigators of this study suggested that Si-rich melt may have played a key role in the dramatic thinning of the lithospheric mantle (e.g. Zhang and Sun et al., 2002; Zhang et al., 2002), and propose here a new approach that will focus on minerals and melt inclusions of these xenoliths. Our objectives include: (1) to study the chemical and isotope compositions of the melt in the lithospheric mantle beneath the NCC, (2) to trace the source of the melt in the mantle and (3) to discuss the connection between plate subduction around the NCC and the lithospheric thinning.The results of this study will shed light on the nature and source of the melt in the Mesozoic mantle and help to understand the mechanism of this important lithospheric thinning.

Abstract:

Project objectives - This study will focus on the Late-Quaternary development and typhoon overwash history identified in back barrier environments at Tai Long Wan, Sai Kung Peninsula. The relatively undisturbed nature of these embayments makes them ideal candidates for a joint study to; (1) Investigate the Quaternary evolution of this small barrier systems (2) Study and predict the response of these systems to sea level change and investigate evidence for higher Holocene sea levels (3) Investigate the geological record of overwash during large typhoons (4) Provide direct land-sea correlation between the marine records of Yim and others from Hong Kong and the terrestrial evolution of the system. Key issues: (1) The establishment of a Quaternary chronostratigraphy for the evolution of this small barrier system and compare it to archaeological dating from the area. (2) Can this system provide a key reference to typhoon activity over the last 6000 years? (3) How would this system react to possible higher future sea level due to global warming? (4) Can ground penetrating radar of this dune system provide meaningful data on the nature of typhoon modification over geological timeframes? (5) How has the morphology of the embayment changed over the last 80 years using aerial photograph interpretation since 1924 and has any noted change been the result of human activity? Problems to be addressed - (1) When and how did the barrier system at Tai Long Wan form. (2) Is a sedimentary record of large typhoons recorded in the back barrier stratigraphy of this embayment. (3) Can the ground penetrating radar tehcnique shed ligfht on the evolution of the duen system and the impact of typhoons. (4) What is the predicted response of this system to possible higher sea levels in the future.

Abstract:

The Earth is an uniquel planet in the universe because of its continental crust, a rocky layer at its surface. Therefore, the growth history of the continental crust is an essential issue to understand the evolution of the Earth. An easy method to estimate continental growth rates is to investigate the age distribution of detrital zircons from large rivers with drainage basins that sample a large area and zircon is the most ideal mineral for isotope geochronological study since it accommodates relatively high contents of U but extremely low Pb during crystallization, and is resistant to secondary geological events. This proposed study will conduct both U-Pb and Lu-Hf isotope analyses of detrital zircons from the Yangtze River sands. The objectives include: (1) to provide an overview of the age spectra of the magmatism in the source, i.e., the drainage of the Yangtze River, (2) to investigate the characteristics of each magmatic generation (juvenile vs. reworking), (3) to calculate the continental growth rate in the source region, (4) To compare the continental growth rate of Chinese continental blocks with that for the other blocks in the world in order to better understand the evolution of the Earth.

Abstract:

(1) The main objective of this project is to determine the timing and tectonic setting of the Southern Margin Volcanic Belt of the North China Craton. There is a hot debate on the age and tectonic setting of this volcanic belt. Some workers propose that the belt formed as an intracontinental rift (Sun et al., 1981; Zhang, 1989; Yang, 1990), whereas others argue that it represents a long-lived, subduction-related, continental margin accretionary belt (Jia, 1985; Chen, 1992). This controversy results from the lack of reliable isotopic, structural and geochemical data for the Southern Margin Volcanic Belt. This project aims to apply an integrated multidisciplinary approach, including field, structural, geochemical and geochronological studies, to resolve this controversial geological issue. (2) We will meet the above objective by: 1) investigating the geological occurrence and distribution of volcanic rocks and associated intrusions in the Southern Margin Volcanic Belt; 2) carrying out field- and laboratory-based structural analysis of the belt in order to work out whether the major structural phase is extensional or compressional, which is critical in discriminating rifting from continental margin arc settings; 3) undertaking detailed petrographic examination of representative thin sections in order to characterize the mineral assemblages and fabrics of these igneous rocks; 4) constraining tectonic settings of the belt by using rock associations and geochemical fingerprints; and (5) dating the eruption and emplacement time of the volcanic rocks and associated intrusions of the belt by utilizing the SHRIMP U–Pb zircon geochronology. (3) The results of this project will not only allow us to work out when and how the Southern Margin Volcanic Belt formed, but will also place a first-order constraint on the configuration of the North China Craton in the proposed Paleo-Mesoproterozoic Columbia (Nuna) supercontinent (Rogers and Santosh, 2002, Zhao et al., 2002, 2004; Pesonen et al., 2003). If the Southern Margin Volcanic Belt represents a Paleo-Mesoproterozoic rift belt, it implies that the southern margin of the North China Craton must have been connected to another continental fragment in the Columbia (Nuna) supercontinent. In contrast, if the belt was a Paleo-Mesoproterozoic, subduction-related, continental margin accretionary belt, it suggests that the southern margin of the North China Craton must have faced an open ocean, not been connected to any other continental blocks in the Columbia (Nuna) supercontinent. The outcomes of this project thus have a long-term impact on a major geological issue related to the reconstruction of the recently proposed Paleo-Mesoproterozoic Columbia (Nuna) supercontinent.

Abstract:

Major advancements in understanding the geological history of the North China Craton have been made in the past a few years, following recognition of three major Paleoproterozoic tectonic belts: the Khondalite Belt, Trans-North China Orogen and Jiao-Liao-Ji Belt in the western, central and eastern parts of the craton, respectively (Zhao et al., 2001, 2005). The Trans-North China Orogen divides the North China Craton into two discrete blocks, named the Eastern and Western Blocks, whereas the Paleoproterozoic Khondalite Belt divides the Western Block into the Yinshan Terrane in the North and the Ordos Terrane in the south, and the Paleoproterozoic Jiao-Liao-Ji Belt lies in the Eastern Block. There is a broad consensus that the Khondalite Belt and Trans-North China Orogen represent two independent Paleoproterozoic continent-continent collisional belts, with the former formed by the collision between the Yinshan and Ordos Blocks to form the coherent Western Block at ~1.9 Ga (Zhao et al., 2005; Xia et al., 2006), and the latter formed by the amalgamation of the Western and Eastern Blocks to form the North China Craton at about 1.85 Ga (Zhao et al., 2001, 2005). There are now coherent outlines of the timing and tectonic processes involved in the Palaeoproterozoic amalgamation and much intensive knowledge concerning the pre-collisional history of these collisional belts that were subsequently incorporated into the North Chian Craton. However, the tectonic nature of the Paleoproterozoic Jiao-Liao-Ji Belt still remains controversial (Yang et al., 1988; Bai and Dai, 1998; He and Ye, 1998; Li et al., 2005). Tectonic models for the Paleoproterozoic Jiao-Liao-Ji Belt range from those invoking the opening and closing of an intra-continental rift in the Eastern Block of the North China Craton (Zhang and Yang, 1988; Li et al., 2005), to those involving a continental collisional belt along which two metamorphic terranes (He and Ye, 1998) or a continent and an island arc (Bai and Dai, 1998) collided to form a coherent continental block. These debates reflect the lack of geological data, especially of structural and geochronological data for the major lithologies of the Jiao-Liao-Ji Belt. This project aims to test these models by carrying out extensive field-based structural investigations followed by detailed geochronological studies on the major lithologies of the Jiao-Liao-Ji Belt. Specifically, the objectives of this project are: (1) to investigate the geological occurrence and distribution of major lithologies in the Jiao-Liao-Ji Belt; (2) to carry out field-based structural analysis of the belt in order to work out whether the major structural phase is extensional or compressional, which is critical in discriminating rifting from continental margin arc settings; and (3) to date the eruption and emplacement time of the metamorphic rocks of the belt by utilizing the LA-ICP-MS and SHRIMP techniques.

Abstract:

Introduction: major source of V and Ti in the world comes from layers or lenses of massive Fe-Ti oxides hosted in layered intrusions, which are considered to be remnants of mafic magma chambers. However, the fundamental process by which V and Ti, generally present in low quantities in mantle-derived magmas, are concentrated to form massive bodies of Fe-Ti oxides is not fully understood. Key issues and problems: A number of layered intrusions hosting Fe-Ti-V oxide deposits in SW China occur in a relatively focused region known as the Panzhihua-Xichang (Pan-Xi) region. It represents an important metallogenic district for V and Ti not only in China but also the world, for instance, oxide mines in the Pan-Xi region account for 6.7% and 35.2% of global production of V and Ti, respectively. The existence of these ore-bearing intrusions in a concentrated region is quite uncommon. It is not clear whether the enrichment of Fe and Ti is a characteristic of the mantle source from which the magma was originated, or related to modification when the magma ascent en route to the surface. It has been shown elsewhere that country rock assimilation is important in generating world-class magmatic Ni-Cu sulfide deposits, including the Noril’sk deposit in Russia and the Voisey’s Bay deposit in Canada. Assimilation of crustal country rocks may also be significant on the formation of magmatic Fe-Ti-V oxide deposits. This study will use stable isotope geochemistry to examine the nature, extent and effect of country rock assimilation on the formation of magmatic Fe-Ti-V oxide deposits. It aims at a better understanding as to whether there is any genetic link between the type of country rock and the origin of the oxide deposits. The Panzhihua and Hongge Fe-Ti-V oxide deposits are chosen in this study due to their excellent exposure and the presence of carbonate rock as the immediate footwall rock. Our previous work suggests that the Pan-Xi ore-bearing layered intrusions are derived from highly evolved gabbroic magmas and that the oxide ores have possibly formed from oxide melts at late-stage. Several key issues are still to be resolved: (1) what is the relation between the late-stage oxide melt and the silicate magma which forms the gabbro? Are they immiscible liquid pairs? (2) what triggers the formation of an oxide liquid? Is it related to the wallrock or any fluid derived from it that the magma interacts with? (3) the formation of large amount of magnetite requires a relatively high oxygen fugacity (oxidizing conditions), is it related to the redox equilibria involving CO2 and graphite from the wallrock? Principal objectives: 1. To evaluate the degree of crustal contamination in the Panzhihua and Hongge intrusions; 2. To examine the nature, extent and effects of assimilation of carbonate wallrock and its link to the formation of Fe-Ti-V oxide deposits in these two ayered intrusions

Abstract:

(1) Fe-Ti-V oxide mines in the Panxi region, SW China, produce 6.7% and 35.2% of global production of V and Ti, respectively. The giant Fe-Ti-V oxide deposits in SW China are unique in that they are hosted in layered intrusions that formed from highly evolved mafic magmas associated with the Emeishan Large Igneous Province (ELIP). The objective is to understand the nature of the parental magmas for the gabbroic intrusions to see if they were originally enriched in Fe, Ti and V , and why the magmas remained so reducing during their evolution; (2)The ore-bearing gabbroic intrusions are spatially and temporally associated with syenitic intrusions in the Panxi region. It is possible that the Fe-Ti-V enrichment in the mafic intrusions was caused by immiscible separation of syenitic magmas. The study will attempt to unravel the relationship between these two types of intrusions; (3) The ore-forming mechanism is uncertain. Our previous work suggests that the oxide ores may have formed from oxide melts. If oxide melts existed, were these melts formed from the silicate magmas, and if so, what triggered their formation? Was wall-rock/melt interaction significant and were fluids an important factor? Did the assimilation of carbonates, which are nearly ubiquitous in the wall rocks and which can change the oxygen fugacity of the magma, play an important role? We will evaluate the influence of crustal contamination and the role of fluids in the genesis of the oxide ores; (4) Ultimately to develop geological models for the occurrence of giant Fe-Ti-V oxide ore deposits in gabbroic intrusions and to use these results to more efficiently explore for new deposits of this type. The proposed project will aid in understanding the exploration potential for other giant ore deposits in the ELIP and elsewhere. 5 The project is part of our long-term research program investigating the genesis and exploration potential of magmatic ore deposits in China. This project provides more opportunities for us to interact with members of the mining industry and to collaborate with scientists in many different countries. The proposed collaboration between the applicants and their colleagues in the local geological surveys and mining companies will ensure that the results of this work can be used by the mining industry.

Permian mafic magmatism and associated Ni-Cu-(PGE) sulfide mineralization in the Eurasian continent

Abstract:

Background of Research Our previous studies have focused on the Permian (~260 Ma) Emeishan Large Igneous Province (ELIP) and advanced the knowledge about the controls on two styles of mineralization: Ni-Cu-(PGE) sulfide and Fe-Ti-V oxide mineralization [1-12]. We have established a geochemical link between the intrusions and flood basalts. The various intrusions and volcanics were thus considered to represent a single magmatic event produced by a same mantle plume. The diversity is explained by variable mantle sources, mantle plume-lithosphere interaction, crustal contamination, or a combination of these processes. On the other hand, the voluminous flood basalts of the Siberian Traps are associated with contemporaneous mafic intrusions hosting the largest sulfide deposits in the world [13-20]. Widely distributed basalts in the Tarim basin in NW China were recently discovered by deep-drill-core and are part of the Permian strata. Because of their poor exposures, little is known about their significance. It is also known that in NW China and North China there are abundant mafic intrusions of possible Permian in age. Examples are the Kalatongke and Huangshan intrusions. These intrusions have been dated by various isotopic systems, to yield a Re-Os isochron age of 281 Ma and a zircon U-Pb age of 274 Ma [21,22]. They are explained to have formed in a post-collisonal extensional environment. It is still not clear about their precise ages, and their relationship with Permian volcanic rocks in Tarim. Nevertheless, these occurrences have important significance as they may link the Siberian Traps, the ELIP, and flood basalts in Tarim to a single magmatic event in Later Permian time. The Re-Os isotopic system has been used to determine if the ore-forming metals were derived from a crustal or mantle source [23]. It has been widely used in Siberia, Hawaii, Iceland basalts, Noril’sk, Sudbery, Voisy’ Bay, and Duluth deposits [24-26]. As many Ni-Cu-(PGE) sulfides are formed due to crustal contamination of mantle-derived magmas [27], the Re-Os system is a powerful tool in petrogenetic studies of such deposits. It is envisioned that they will be of considerable importance in solving the problems and in providing new constraints on magmatic processes and ore genesis across the Eurasian continent. Key issues and problems Extensively Permian magmatism is wide-spread all over the Eurasia and includes the well known ~252 Ma Siberian Traps and ~260 Ma Emeishan Large Igneous Province in NW China. In addition, Permian mafic intrusions and flood basalts are known to occur across the entire Eurasian continent including NW China and North China. However, there is no attempt to link all these occurrences in the context of Permian igneous activities, partly because of a lack of data for Permian rocks in NW China and North China. The occurrence of these rocks raises several questions: Were all these igneous activities produced by a single magmatic event, i.e. a super plume? Is there potential in NW China and North China to host similar deposits identified in Emeishan and Siberia? In particular, what are the relationships between the Siberian Traps, Emeishan Large Igneous Province, Flood Basalts in Tarim and Permian mafic intrusions in NW China and North China? Linking these would have important significance for understanding the processes that formed the LIPs and their ore deposits. Objectives The principal objective of this proposed research is to document the Permian mantle-derived intrusions across NW China and North China. Utilizing PGE and Re-Os isotopic geochemical data for individual intrusive bodies, we will aim to constrain the origin of these rocks and to understand the relationship between these igneous rocks, Siberian Traps and Emeishan Flood Basalt Province in SW China. Our major goal will be to determine the nature and timing of the mineralization within the intrusions. We will provide a better understanding of the factors controlling the diversity of rock types and ore deposits. Ultimately our work will provide information about the mineralization potential of the Permian igneous bodies across the Eurasian continent. Key references: 1.
