2Helium,Argon,and Xenon Isotopic Compositions of Ore-forming Fluids in Jinding-Baiyangping Polymetallic Deposits,Yunnan,Southwest China显示文摘The Jinding superlarge lead and zinc deposit has attracted the attention of geologists of the world and itsmetal logenesis has long been in dispute. This paper takes the Jinding deposit and the Baiyangping Cu-Ag-Co deposit which was recently found at about 30 km north of Jinding as one ore belt, and, based on researches on the helium, argon, and xenon isotopic compositions of primary inclusions in ore-forming solutions of the main stage, the authors have found that the 3He/4He ratio of the ore-forming fluid is 2.7×10-6 (varying from 0.19 to 1.97 Ra), the 4He/40Ar ratio (0.24-3.12) is close to the mantle characteristic ratio, and the xenon isotopic composition and evolution show characters of the mantle xenon. The above results reveal the characteristics of mantle source and crust-mantle fluid mixing (mantle helium reaching 32%) and the metallogenic contributions of the deep processes in the Jinding-Baiyangping ore belt.XUE Chunji WANG Denghong CHEN Yuchuan YANG Jianmin YANG Weiguang 2000Acta Geologica Sinica(English Edition)2000,74,3:17
3Effects of hydrocarbon generation on fluid flow in the Ordos Basin and its relationship to uranium mineralization显示文摘诺思中国的 Ordos 盆是不仅一个重要的铀矿化作用省,而且在中国的油,气体和煤的一个主要制片人。在铀矿化作用和烃之间的基因关系被认出了由很多以前的研究,而是它很好没以盆液体的水动力学被理解流动。我们在以前的研究证明了在 Ordos 侏罗记节的上面的部分的白垩纪铀矿化作用的优先的本地化可能与在向上的流动之间的接口有关,减少液体并且向下流动,氧化液体。这个接口可能被在与不平衡沉积压缩有关的液体过压之间的相互影响控制了并且它驾驶了向上的流动,和地志的地势,它开车了向下流动。在这研究,我们执行了为对液体过压的发展的油和煤气的产生的贡献的数字建模,除了沉积压缩并且加热。当烃产生没被考虑时,我们的结果显示当烃产生被考虑时,液体过压非常与模拟比较在白垩纪期间被加倍。而且,在沉积的结束的液体过压驱散相对没有烃产生盒子慢下来。这些结果建议烃产生可能在铀矿化作用,不是仅仅在规定减少为矿化作用要求的代理人,而且在贡献驱动力维持向上的流动起了一个重要作用。Chunji Xue Guoxiang Chi Wei Xue 2011Geoscience Frontiers2011,2,3:12

5Hydrodynamic regime as a major control on localization of uranium mineralization in sedimentary basins显示文摘Uranium deposits in sedimentary basins can be formed at various depths,from near surface to the basement.While many factors may have played a role in controlling the location of mineralization,examination of various examples in the world,coupled with numerical modeling of fluid flow,indicates that the hydrodynamic regime of a basin may have exerted a major control on the localization of uranium deposits.If a basin is strongly overpressured,due to rapid sedimentation,abundance of low-permeability sediments or generation of hydrocarbons,fluid flow is dominantly upward and uranium mineralization is likely limited at shallow depths.If a basin is moderately overpressured,upward moving fluids carrying reducing agents may meet downward moving,oxidizing,uranium-bearing fluids in the middle of the basin,forming uranium deposits at moderate depths.If a basin is weakly or not overpressured,either due to slow sedimentation or dominance of high-permeability lithologies,minor topographic disturbance or density variation may drive oxidizing fluids to the bottom of the basin,leaching uranium either from the basin or the basement,forming unconformity-type uranium deposits.It is therefore important to analyze the hydrodynamic regime of a basin in order to predict the most likely type and location of uranium deposits in the basin.CHI GuoXiang XUE ChunJi 2014Science China Earth Sciences2014,57,12:6

7Hydrodynamic Links between Shallow and Deep Mineralization Systems and Implications for Deep Mineral Exploration显示文摘Deep mineral exploration is increasingly important for finding new mineral resources but there are many uncertainties.Understanding the factors controlling the localization of mineralization at depth can reduce the risk in deep mineral exploration.One of the relatively poorly constrained but important factors is the hydrodynamics of mineralization.This paper reviews the principles of hydrodynamics of mineralization,especially the nature of relationships between mineralization and structures,and their applications to various types of mineralization systems in the context of hydrodynamic linkage between shallow and deep parts of the systems.Three categories of mineralization systems were examined,i.e.,magmatic-hydrothermal systems,structurally controlled hydrothermal systems with uncertain fluid sources,and hydrothermal systems associated with sedimentary basins.The implications for deep mineral exploration,including potentials for new mineral resources at depth,favorable locations for mineralization,as well as uncertainties,are discussed.CHI Guoxiang XU Deru XUE Chunji LI Zenghua Patrick LEDRU DENG Teng WANG Yumeng SONG Hao 2022Acta Geologica Sinica(English Edition)2022,96,1:5
8An Updated Database and Spatial Distribution of Landslides Triggered by the Milin, Tibet M_(w)6.4 Earthquake of 18 November 2017显示文摘The M_(w)6.4 earthquake on November 18, 2017 in Milin County, Nyingchi City, Tibet triggered thousands of landslides. By comparing visual interpretation of satellite images acquired shortly before and after the earthquake and field survey, we have created a new landslide database which includes 3 130 coseismic landslides, each with an area of 0.01 to 4.35 km^(2). Six factors(elevation, slope angle, slope aspect, lithology, distance from the epicenter and distance from the seismogenic fault) were selected to correlate with the coseismic landslides. In addition, the area and density of landslides were counted as indicators. Results show that most landslides occurred where the elevation is between 2 000–3 000 m, with a 40°–50° slope angle and S, E or SE slope aspect, schist or gneiss lithologies, 10–15 km from the epicenter, and 5 km within the seismogenic fault. Most of the landslides, triggered by the M_(w)6.4 earthquake, are concentrated near the seismogenic fault rather than at the epicenter, indicating that the seismogenic structure is more influential than the location of the epicenter. Our findings may differ from other landslide database due to temporal image acquisition, interference from weather, and image resolution.Yuandong Huang Chong Xu Xiaolong Zhang Chunji Xue Shiyuan Wang 2021Journal of Earth Science2021,32,5:4
9Cenozoic Mineralization in China,as a Key to Past Mineralization and a Clue to Future Prospecting显示文摘Many Cenozoic metal deposits have been found during the past decade. Among them, the Fuwan Ag deposit in Guangdong is the largest Ag deposit in China. Besides, the largest Cu deposit of China in Yulong, Tibet, the largest Pb-Zn deposit of China in Jinding, Yunnan, and the largest Au deposit of China in Jinguashi,Taiwan, were also formed in the Cenozoic. Why so many important 'present' deposits formed during such a short period of geological history is the key problem. The major reason is that different tectonic settings control different kinds of magmatic activity and mineralization at the same time. In southwestern China, porphyry-type Cu deposits such as Yulong were formed during the early stage of the Himalayan orogeny, sediment-hosted Pb-Zn deposits such as Jinding were formed within intermontane basins related to deep faults, and carbonatite-related deposits such as the Maoniuping REE deposit and alkalic magmatic rock-related deposits such as the Beiya Au deposit originated from the mantle source.WANG Denghong CHEN Yuchuan XU Jue YANG Jianmin XUE Chunji YAN Shenghao 2000Acta Geologica Sinica(English Edition)2000,74,3:4
10Expansion of the South China Sea basin:Constraints from magnetic anomaly stripes,sea floor topography,satellite gravity and submarine geothermics显示文摘The widely distributed E-W-trending magnetic anomaly stripes in the central basin and the N-Etrending magnetic anomaly stripes in the southwest sub-basin provide the most important evidence for Neogene expansion of the South China Sea.The expansion mechanism remains,however,controversial because of the lack of direct drilling data,non-systematic marine magnetic survey data,and irregular magnetic anomaly stripes with two obvious directions.For example,researchers have inferred different ages and episodes of expansion for the central basin and southwest sub-basin.Major controversy centers on the order of basinal expansion and the mechanism of expansion for the entire South China Sea basin.This study attempts to constrain these problems from a comprehensive analysis of the seafloor topography,magnetic anomaly stripes,regional aeromagnetic data,satellite gravity,and submarine geothermics.The mapped seafloor terrain shows that the central basin is a north-south rectangle that is relatively shallow with many seamounts,whereas the southwest sub-basin is wide in northeast,gradually narrows to the southwest,and is relatively deeper with fewer seamounts.Many magnetic anomaly stripes are present in the central basin with variable dimensions and directions that are dominantly EWtrending,followed by the NE-,NW- and NS-trending.Conversely such stripes are few in the southwest sub-basin and mainly NE-trending.Regional magnetic data suggest that the NW-trending Ailaoshan-Red River fault extends into the South China Sea,links with the central fault zone in the South China Sea,which extends further southward to Reed Tablemount.Satellite gravity data show that both the central basin and southwest sub-basin are composed of oceanic crust.The Changlong seamount is particularly visible in the southwest sub-basin and extends eastward to the Zhenbei seamount.Also a low gravity anomaly zone coincides with the central fault zone in the sub-basin.The submarine geothermic distribution demonstrates that the southwest sub-basin has a higher geothermal value than the central basin,and that the central fault zone is defined by a low thermal anomaly.This study suggests that NW-SE expansion of the southwest subbasin is later than the N-S expansion of the central basin with the sub-basin extending into the central basin and with both expansions ending at the same time.The expansion of southwestern sub-basin,similar to the Japanese Sea,is likely caused by left-lateral strike slip on the central fault zone in the South China Sea,which may have significance for finding oil and gas in this region.Xuezhong Yu Chunji Xue Haigang Shi Weiping Zhu Yinghui Liu Hang Yin 2017Geoscience Frontiers2017,8,1:3

12Engineering porosity into trimetallic PtPdNi nanospheres for enhanced electrocatalytic oxygen reduction activity显示文摘Platinum(Pt)-based multi-metallic nanostructures show great promise as electrocatalysts for the oxygen reduction reaction(ORR) in fuel cell cathodes. Herein, we report a simple, one-step surfactant-directed synthetic strategy to directly synthesize tri-metallic PtPdNi mesoporous nanospheres(PtPdNi MNs) in a high yield. The synthesis could be accomplished in aqueous solution at mild reaction temperature(40C)without needing any organic solvent, yielding well-dispersed PtPdNi MNs with uniform shape and narrow size distribution. Benefitting from their unique mesoporous and highly open structure and tri-metallic composition, the as-synthesized PtPdNi MNs demonstrate superior catalytic activity and stability for ORR in acidic solution in comparison with PtPdNi nanodendrites(PtPdNi NDs), PtPd MNs and commercial Pt/C catalyst. The present approach may open a reliable path to the design of advanced electrocatalysts with desired performance.Chunjie Li You Xu Yinghao Li Hongjie Yu Shuli Yin Hairong Xue Xiaonian Li Hongjing Wang Liang Wang 2018Green Energy & Environment2018,3,4:1

14Mierogranular enclaves in island- arc andesites: A possible link between known epithermal Au and potential porphyry Cu-Au deposits in the Tulasu ore cluster, western Tianshan, Xinjiang, China显示文摘Zhao Xiaobo Xue Chunji David T A Symons 2014Journal ofAsian Earth Sciences2014,85,:1
15Multiple and prolonged porphyry Cue Au mineralization and alteration events in the Halasu deposit, Chinese Altai, Xinjiang,northwestern China显示文摘The Halasu area is located in the southeastern margin of the Chinese Altai in Xinjiang, China. It is part of the Altaid orogenic collage where a number of porphyry-type Cue Moe Au deposits have been discovered in recent years. Geological mapping and drilling indicate the presence of various mineralized porphyritic intrusions in the Halasu Cue Au deposit, which is currently under exploration. Ue Pb dating of zircon crystals from four different mineralized porphyries reveals three significantly different ages of magmatic intrusion, i.e., ca. 372e382 Ma granodioritic porphyry and porphyritic granite, ca. 266 Ma quartz monzonitic porphyry, and ca. 216 Ma quartz dioritic porphyry. Ree Os dating of molybdenite from veinletdissemination ores in the granodioritic porphyry yields an age of mineralization of ca. 377 Ma, and Ar e Ar dating of K-feldspar from K-feldsparequartzechalcopyrite veins produces ages of ca. 269 and ca.198 Ma. The mineralization(and alteration) ages correspond broadly to the three episodes of magmatic intrusion, suggesting three overprinting porphyry mineralization events that are significantly separated in time. The first episode of porphyry intrusion and mineralization may be related to the magmatic arc being above a plate subduction zone, and the second was formed in a late-collisional environment during the closing of the Junggar Ocean, whereas the third episode of mineralization took place in the postcollisional stage. This case study suggests that in orogens where major porphyry deposits have been found in magmatic arc environments, the potential of discovering late- to post-collisional porphyry deposits cannot be neglected; conversely, in orogens where most porphyry deposits have late- to postcollisional ages, more attention should be paid to porphyries that were formed earlier in magmatic arc environments.Chunji Xue Guoxiang Chi Xiaobo Zhao Ganguo Wu Zhanfeng Zhao Lianhui Dong 2016Geoscience Frontiers2016,7,5:1

20Introduction to thematic section on hydrodynamic studies of mineralization显示文摘1.Introduction Most metallic mineral deposits formed from hydrothermal fluids,and the mineralization processes include both chemical (e.g.,fluid-rock and fluid-fluid interactions)and physical(e.g., fluid flow)aspects.More attention has been paid to the chemical processes than the physical ones,even though the latter is equally important in controlling the formation of mineral deposits and their localization.Nevertheless,a number of studies have been carried out regarding the hydrodynamics of fluid flow associated with ore mineralization(e.g.,Cathles,1981,1997; Garven and Raffensperger,1997;Cathles and Adams,2005; Cox,2005;Ingebritsen et al.,2006),and it is timely to eval-Guoxiang Chi Department of Geology,University of Regina, Regina,Saskatchewan,Canada Chunji Xue State Key Laboratory of Geological Processes and Mineral Resources,China University of Geosciences, Xueyuan Road 29,Beijing 100083,China 2011Geoscience Frontiers2011,2,3:0
