| 1 | Re-Os isotope dating of molybdenites in the Huang-shaping Pb-Zn-W-Mo polymetallic deposit, Hunan Province, South China and its geological significance显示文摘The large-scale Huangshaping Pb-Zn-W-Mo polymetallic deposit is located in the central Nanling min- eralization zone, South China. Six molybdenite samples from the Huangshaping deposit were selected for Re-Os isotope measurement in order to define the mineralization age of the deposit. It yields a Re-Os isochron age of 154.8±1.9 Ma (2σ ), which is in accordance with the Re-Os model ages of 150.9― 156.9 Ma. This age is about 7 Ma younger than their host granite porphyry, which was dated as 161.6±1.1 Ma by zircon U-Pb method using LA-ICPMS. All these ages demonstrate that the Huang- shaping granite and related Pb-Zn-W-Mo deposit occurred in the middle Yanshanian period, when many other granitoid and related ore deposits emplaced and formed, e.g. the Qitianling granite and Furong tin deposit, the Qianlishan granite and giant Shizhuyuan W-Sn-Mo-Bi deposit and Jinchuantang Sn-Bi deposit in the nearby area. They constitute the main part of the magmatic-metallogenic belt of southern Hunan, and represent the large-scale metallogeny in middle Yanshanian in the area. The lower rhenium content in molybdenite of Huangshaping deposit suggests that the ore-forming material was mainly of crust origin. | YAO JunMing HUA RenMin QU WenJun QI HuaWen LIN JinFu DU AnDao | 2007 | Science China Earth Sciences2007,50,4: | 29 |
| 2 | Metallogenesis related to Mesozoic Granitoids in the Nanling Range, South China and Their Geodynamic Settings显示文摘Affected by the compressive stress from the South-Central (Indo-China) Peninsula, the Indosinianorogenesis, characterized by collision, thrust and uplifting, took place inside the South China Plate during 250?230 Ma.The ages of the Indosinian granitoids in the Nanling Range and vicinity areas are mostly 240?205 Ma, indicating that theywere emplaced in both late collision and post-collision geodynamic environments. No important granite-relatedmetallogenesis occurred in this duration. A post-orogenic setting started at the beginning of the Yanshanian Period, whichcontrolled large-scale granitic magmatism and related metallogenesis. This paper makes the first attempt to divide theYanshanian Period into three sub-periods, i.e. the early, middle and late Yanshanian Periods, based mainly on the featuresof magmatism, especially granitoids and related metallogenesis and their geodynamic environments. The magmaticassociation of the Early Yanshanian (about 185?170 Ma) comprises four categories of magmatism, i.e. basalt, bimodalvolcanics, A-type granite and intraplate high-K calc-alkaline (HKCA) magmatism, which indicates an extension-thinningof lithosphere and upwelling of mantle material to a relative small and local extent. Pb-Zn, Cu and Au mineralizationsassociated with HKCA magmatism represents the first high tide of Mesozoic metallogenesis in the Nanling Range area.During the middle Yanshanian, the lithosphere was subjected to more extensive and intensive extending and thinning, andhence mantle upwelling and basaltic magma underplating caused a great amount of crust remelting granitoids. This periodcan be further divided into two stages. The first stage (170?150 Ma) is represented by large-scale emplacement of crustremelting granites with local tungsten mineralization at its end. The second stage (150?140 Ma) is the most important timeof large-scale mineralizations of non-ferrous and rare metals, e.g. W, Sn, Nb-Ta, Bi, Mo, Be, in the Nanling Range area.The late Yanshanian (140?65 Ma) was generally characterized by full extension and breakup of the lithosphere of SouthChina. However, owing to the influence of the Pacific Plate movement, the eastern part of South China was predominatedby subduction-related compression, which resulted in magmatism of calc-alkaline and shoshonite series and relatedmetallogeneses of Au, Ag, Pb-Zn, Cu and (Mo, Sn), followed by extension in its late stage. In the Nanling Range area, thelate Yanshanian magmatism was represented by granitic volcanic-intrusive complexes and mafic dikes, which aregenetically related to volcanic-type uranium and porphyry tin deposits, and the mobilization-mineralization of uraniumfrom pre-existing Indosinian granites. | HUA Renmin CHEN Peirong ZHANG Wenlan YAO Junming LIN Jinfu ZHANG Zhanshi GU Shengyan LIU Xiaodong QI Huawen | 2005 | Acta Geologica Sinica(English Edition)2005,79,6: | 22 |
| 3 | Zircon U-Pb dating confirms existence of a Caledonian scheelite-bearing aplitic vein in the Penggongmiao granite batholith, South Hunan显示文摘Granite at Penggongmiao is a large batholith in the Nanling Range, with an outcrop area of over 900 km 2 . There are many scheelite-quartz veins around the granite. LA-ICP-MS U-Pb dating was carried out for zircons from the granite. The middlecoarse-grained biotite granite has U-Pb ages of 435 to 436 Ma. Ages of 426.5±2.5 Ma were obtained for aplitic dyke cross-cutting the granite. The scheelite of magmatic origin in the aplite dyke was identified from petrographic investigation. This demonstrates that W-bearing granites of Early Paleozoic (corresponding to the Caledonian orogensis in the traditional sense) occur in the Nanling Range. This finding has important implications for the ore-forming potential of Paleozoic granites and on the extent of Mesozoic mineralization. Thus it merits performing an intensive study of Paleozoic granites in South China. The occurrences of aplite or microgranite may be an indicative of the Caledonian tungsten granites and associated W mineralization. | ZHANG WenLan WANG RuCheng LEI ZeHeng HUA RenMin ZHU JinChu LU JianJun XIE Lei CHE XueDong ZHANG RongQing YAO Yuan CHEN Jun | 2011 | Chinese Science Bulletin2011,56,19: | 23 |
| 4 | He-Ar isotope geochemistry of the Yaoling-Meiziwo tungsten deposit,North Guangdong Province:Constraints on Yanshanian crust-mantle interaction and metallogenesis in SE China显示文摘Isotopic abundances and ratios of He and Ar found in inclusion fluids in pyrites formed in the Yaoling-Meiziwo tungsten miner-alization epoch show that the concentration of 4He varies widely,from 1.54×10-7 cm3 STP/g to 2609×10-7 cm3 STP/g.3He is 0.759×10-12 cm3 STP/g-3.463×10-12 cm3 STP/g.3He/4He is 0.0043-4.362 Ra,varying from crustal to mantle values.The concen-tration of 40Ar ranges from 0.624×10-7 cm3 STP/g to 8.89×10-7 cm3 STP/g.The 40Ar/36Ar varies extensively,from 330 to 2952,between atmospheric and crustal or mantle radiogenic values.Mantle-derived He is present in ore-forming fluids and the calcu-lated average proportion of the mantle He is 22%;the maximum is 67%.Our research results show that mantle-derived fluids play a significant role in tungsten mineralization.The fractionation of He and Ar indicate that there was 4He-enriched air-saturated water(MSAW) in the ore-forming fluid.The ore-forming fluid was a mixture of mantle fluid,crustal magmatic fluid and MSAW.The occurrence of a mantle component in ore-forming fluid indicates the large-scale W and Sn mineralization,including Yaol-ing-Meiziwo,in southeastern China was the result of crust and mantle interaction.The underplating or intrusion of voluminous basaltic magma formed by partial melting of the upper mantle provided the necessary heat to cause partial melting of the crust and the generation of voluminous S-type granitic magmas.Crustal magmatic fluid and mantle fluid with high 3He/4He were released from magma crystallization and fractionation,mixed with the circulating modified air-saturated water,and filled the extensional tectonic fractures,leading to the formation of world-class W and Sn deposits in southeastern China. | ZHAI Wei SUN XiaoMing WU YunShan SUN YanYan HUA RenMin YE XianRen | 2012 | Chinese Science Bulletin2012,57,10: | 16 |

| 6 | Zircon LA-ICP-MS U-Pb dating and Sr-Nd isotope study of the Guposhan granite complex, Guangxi, China显示文摘Zircon U-Pb dating by the LA-ICP-MS method was applied to determining the ages of different units of the Guposhan granite complex, among which the East Guposhan unit is 160.8±1.6 Ma, the West Guposhan unit is 165.0±1.9 Ma, and the Lisong unit is 163.0±1.3 Ma in age. Much similarity in ages of the three units has thus proved that the whole Guposhan granite complex was formed in the same period of time. They were the products of large-scale granitic magmatism through crust-remelting in the first stage of the Middle Yanshanian in South China. However, the three units have differences both in petrology and in geochemistry. Besides the differences in major, trace and rare-earth elements, they are distinct in their Rb-Sr and Sm-Nd isotopic compositions. The East Guposhan unit and Lisong unit and its enclaves have a similar (87Sr/86Sr)i value of 0.7064 with an average of εNd(t)=-3.03, indicating that more mantle material was evolved in the magma derivation; whereas the West Guposhan unit has a higher (87Sr/86Sr)i value of 0.7173 but a lower εNd(t) value of -5.00, and is characterized by strong negative Eu anomalies and higher Rb/Sr ratios, suggesting that its source materials were composed of relatively old crust components and new mantle-derived components. In addition, an inherited zircon grain in the East Guposhan unit (GP-1) yielded a 206Pb/238U age of 806.4 Ma, which is similar to the ages of the Jiulin cordierite granite in northern Jiangxi and of the Yinqiao migmatic granite in Guangxi in the HZH granite zone. All this may provide new evidence for Late Proterozoic magmatism in the HZH granite zone. | GU Shengyan HUA Renmin QI Huawen | 2007 | Chinese Journal Of Geochemistry2007,26,3: | 3 |

| 10 | Geochemical Characteristics of Rare Earth Elements of Guidong Granitic Complex and Their Relationship with Uranium Mineralization显示文摘The Guidong granitic complex is constituted by Luxi pluton, Xiazhuang pluton, Maofeng pluton, Sundong pluton, Aizi pluton and Siqian pluton, which intruded in Indosinian and early Yanshanian Periods. These plutons varies from each other not only in major element content, aluminium saturation index, but also in ∑REE, δ_ Eu , and LREE/HREE, (La/Yb)_N, (La/Sm)_N and (Gd/Yb)_N ratios. Uranium mineralization is mainly hosted by strong peraluminous granites, which has undergone intense fluid-rock interaction, and their REE compositions are characterised by M-type tetrad effects and lower ∑REE, δ_ Eu value, LREE/HREE, (La/Yb)_N, (La/Sm)_N and (Gd/Yb)_N ratios. | Zhang Zhanshi Hua Renmin Liu Xiaodong Deng Ping Wu Lieqin | 2005 | Journal of Rare Earths2005,23,6: | 1 |

| 13 | Rb-Sr Dating of Pyrite and Quartz Fluid Inclusions and Origin of Ore-forming Materials of the Jinshan Gold Deposit, Northeast Jiangxi Province, South China显示文摘The Jinshan gold deposit is located in the Northeast Jiangxi province,South China,which related to the ductile shear zone.It contains two ore types,i.e.the alteration-type ore and the goldbearing quartz vein ore.Rb-Sr age dating is applied to both gold-bearing pyrite in the alteration-type ore and fluid inclusion in the gold-bearing quartz vein to make clear the time of the gold mineralization of the Jinshan deposit.Analytical results of this study yielded that the age of the alteration-type ore bodies is about 838±110Ma,with an initial87Sr/86Sr value of 0.7045±0.0020.However,the age of the gold-bearing quartz vein-type ore is about 379±49Ma,and the initial87Sr/86Sr is 0.7138±0.0011.Based on the age data from this work and many previous studies,the authors consider that the Jinshan gold deposit is a product of multi-staged mineralization,which may include the Jinninian,Caledonian,Hercynian,and Yanshanian Periods.Among them,the Jinninian Period and the Hercynian Period might be the two most important ore-forming periods for Jinshan deposit.The Jinninian Period is the main stage for the formation of alteration-type ore bodies,while the Hercynian Period is the major time for ore bodies of gold-bearing quartz vein type.The initial values of the87Sr/86Sr from this study,as well as the previous isotope and trace element studies,indicate that the ore-forming materials mainly derived from the metamorphic wall rocks,and the ore-forming fluids mainly originated from the deep metamorphic water. | MAO Guangzhou HUA Renmin LONG Guangming LU Huijuan | 2013 | Acta Geologica Sinica(English Edition)2013,87,6: | 1 |

| 18 | The relationship between epithermal and low temperature mineralizations显示文摘THE term epithermal as a kind of hydrothermal mineralization was first used by Lindgren in 1933. It describes those ore-forming systems occurring at depths mainly less than 1 km, and at temperatures less than300℃. Epithermal deposits of Cenozoic ages are widely distributed in the Circum-Pacific belt, especiallyin the Southwest Pacific area. From the 1980s on, the study of epithermal ore deposits became an important field of mineral deposit research. Hayba et al.and Hedenquist classified the epithermal systemas adularia-sericite or acid-sulphate types, and low sulphidation or high sulphidation types, respectively.The low temperature mineralization, which was exemplified by the deposits in southwest China, refers tothe system at temperature mainly less than 200℃. Besides the distinction in temperature, however, thereexist many differences between epithermal and low temperature mineralizations. | HUA Renmin State Key Laboratory of Mineral Deposit Research, Nanjing University, Nanjing 210093, China | 1999 | Chinese Science Bulletin1999,44,S2: | 0 |
| 19 | A Study on the Kunyang Aulacogen显示文摘The Kunyang Aulacogen is a continental rift which initiated at the beginning of the Middle Proterozoic. Itwas generated on the rigid continental crust represented by the crystalline Kangding Complex, and is boundedby two N-S-trending deep faults--Anninghe-Luzhijiang Fault and Xiaojiang Fault. Its early stage of rupturewas characterized by alkalinc mafic igneous activities in the Dahongshan Group and Hekou Group. Duringthe later tensile-depression stage the aulacogen evolved into a graben where scdimentation of the KunyangGroup took place. The sedimentary sequence comprises terrestrial red beds, algal dolomite, marine black shaleand carbonate rocks which are quite typical of rift sedimentary association, and contains stratabound copperdeposits of the well-known Dongchuan type. | Hua Renmin Nanjing University, Nanjing,Jiangsu Province | 1991 | Acta Geologica Sinica(English Edition)1991,65,2: | 0 |
