| 2 | Origin of ore-forming fluids of the Dachang Sn-polymetallic ore deposit: Evidence from helium isotopes显示文摘The ore genesis model for the Dachang Sn-polymetallic ore deposit has long been in dispute, and the major debate focuses on whether the stratiform and massive orebodies formed during the Yanshanian magmatic-hydro-thermal event or they were products of Devonian syn-sedi-mentary exhalative-hydrothermal event. This note presents new helium isotope data from fluid inclusions of four pyrites and one fluorite. The pyrites were collected from the stratiform and massive orebodies in the deposit, and their 3He/4He ratios are significantly higher than 1, ranging from 1.7 to 2.5 Ra, which indicates a mantle component in the responsible hydrothermal fluids. It is suggested that the ore-forming fluids were a mixture of deep circulating seawater and a mantle-derived fluid, which are similar to many of those modern submarine hydrothermal fluids. In contrast, the fluorite, collected from a granite-related hydrothermal vein in the deposit, shows a low 3He/4He ratio of 0.7 Ra, which indicates no mantle component | Kuidong Zhao Shaoyong Jiang Hongquan Xiao Pei Ni | 2002 | Chinese Science Bulletin2002，47，12： | 28 |
| 3 | Sm-Nd isotope dating of hydrothermal calcites from the Xikuangshan antimony deposit,Central Hunan显示文摘The research on Samarium-Neodymium isotope systematics of hydrothermal calcites from the Xi-kuangshan antimony deposit, Central Hunan, places precise timing constraints on the Sb mineralization in this area. It is revealed that the Xikuangshan deposit formed during the late Jurassic-early Cretaceous Period, the early- and late-stage mineralization took place at (155.5±1.1) Ma and (124.1±3.7) Ma, respectively. The accurate age determination of mineralization is very crucial for revealing the super-enrichment mechanism of the element Sb at the Xikuangshan mine, and lays some foundations for the further understandings of its ore genesis and mineralization mechanism. | PENG Jiantang HU Ruizhong LIN Yuanxian ZHAO Junhong | 2002 | Chinese Science Bulletin2002，47，13： | 19 |
| 4 | N_2-Ar-He systematics and source of ore-forming fluid in Changkeng Au-Ag deposit, central Guangdong, China显示文摘Changkeng Au-Ag deposit is a newly-discovered new type precious metal deposit. N2-Ar-He systematics studies and 3He/4He and δD-δ18O composition analyses show that the ore-forming fluid of the deposit is composed mainly of formation water (sedimentary brine) but not of meteoric water, which was thought to be source of the ore-forming fluid by most previous researchers. The content of mantle-derived magmatic water in the ore-forming fluid is quite low, usually lower than 10%. According to the source of the ore-forming fluid, the Changkeng Au-Ag deposit should belong to sedimentary brine transformed deposits. From the Late Jurassic to the Early Cretaceous Period, with deposition and accumulation of thick sediments in Sanzhou Basin, the formation water in the sedimentary layers was expelled from the basin because of overburden pressure and increasing temperature. The expelled fluid moved laterally along sedimentary layers to the margin of the basin, and finally moved upward along a gently-dipping | 孙晓明 孙凯 陈炳辉 陈敬德 David I.Norman | 1999 | Science China Earth Sciences1999，42，5： | 12 |
| 5 | A MATHEMATICAL MODEL FOR RESERVOIR SEDIMENTATION AND FLUVIAL PROCESSES显示文摘This paper consists of two parts: mechanism of non-equilibrium transport of non-uniform sediment and its application in the mathematical model. Based on a statistic approach of sediment transport proposed by the authors, a 1 - D equation of non-e- quilibrium transport for various size group of sediment particles is developed. Then equations to predict change of sediment concentration and the corresponding changes in size distribution of suspended load and bed material are also derived. The conception that changes in size distribution are interrelated to sediment-carrying capacity is expounded. These results reveal the essence of sediment transport of non-uniform sediment particles. In the second part a mathematical model incorporating the mentioned equations to compute deposition and scouring in reservoirs as well as the fluvial processes of river channels has been developed. Verification of the model agrees well with field data. | Han Qiwei and He Mingmin (Senior Research Engineers, Dept. of Sedimentation Eng. Inst. of Water Conservancy and Hydroelectric Power Research.)

| 6 | Fluid mixing as the mechanism of formation of the Dajing Cu-Sn-Ag-Pb-Zn ore deposit,Inner Mongolia ——Fluid inclusion and stable isotope evidence显示文摘Dajing Cu-Sn-Ag-Pb-Zn ore deposit, in the Inner Mongolia Autonomous Region of China, is a fissure-filling hydrothermal ore deposit. The d D values of quartz-hosted inclusion water are centered at -100 — -130. The d 34S values of sulfide ore minerals and d 13C values of carbonate gangue minerals vary from 0.3 to 2.6 and from -2.9 to -7.0, respectively. Integrated isotopic data point to two major contributions to the mineralizing fluid that include a dominant meteoric-derived groundwater, and sulfur and carbon species from hypogene magma. Linear trends are exhibited on the gaseous H2O versus CO2 plot, and plots of CO, N2, CH4, and C2H6. It is shown by quantitative simulation that magma degassing cannot explain the linear trends. Hence, these linear trends are interpreted in terms of mixing of CO2-rich magmatic fluid with meteoric-derived groundwater. The groundwater circulated in Paleozoic sedimentary rocks and absorbed CO, N2, CH4, C2H6 and radiogenic Ar from organic matter. Cooling effects resulting from mixing have caused the precipitation of ore minerals. | 刘伟 李新俊 谭骏 | 2003 | Science China Earth Sciences2003，46，7： | 8 |
| 7 | Diagenetic-metallogenic ages of pyritic cherts and their implications in Mojiang nickel-gold deposit in Yunnan Province,China显示文摘Diagenetic-metallogenic ages of pyritic cherts formed by the syn-sedimentation of hydrothermal vent and ages of the Jinchang Rock Formation in the Mojiang large nickel-gold deposit in the Ailaoshan gold metallogenic belt have been discussed on the basis of chronology of isotopic geochemistry. Nickel-gold-bearing pyritic cherts in the mining were formed by syn-sedimentation of hydrothermal vent in the Late Devonian, i.e. age by Sm-Nd isochronal method (t) = (358±8.6) (2σ) Ma and age by Rb-Sr isochronal method (t) = (354.7±0.72) (2σ) Ma. On the other hand, deep-water cherts from the Jinchang Rock Formation of the Upper Devonian in the area were initiated at the same time; that is, age by Sm-Nd isochronal method (t) = (359(+21) (2(7) Ma and age by Rb-Sr isochronal method (t) = (358.02±0.30) (2σ) Ma. | FANG Weixuan HU Ruizhong XIE Guiqing SU Wenchao QI Liang | 2001 | Chinese Science Bulletin2001，46，21： | 7 |

| 10 | Geologic and geochemical features of the volatile-rich ore fluid and its tracing and dating in the Xuebaoding Beryl-Scheelite Vein Deposit,China显示文摘Laser Raman spectrochemical analysis on single inclusion reveals that multi-phase fluid inclusions exist in the Xuebaoding Beryl- Scheelite Vein Deposit. Besides the solid daughter mineral, there are vapor CO2, liquid CO2, water-deficient CO2 and salt water solution from its center to the border. A close study on the fluid inclusion components and carbon, oxygen, helium and argon isotope tracing and dating suggests that the volatile-rich ore fluid might derive from postmagmatic fluid and rare element enrichment is the result of the mixture of the plutonic alkali granite with crustal material. | 曹志敏 任建国 郑建斌 徐仕进 李佑国 王汝成 T.SHOJ H.KANEDA S.KABAYASHI | 2002 | Science China Earth Sciences2002，45，8： | 6 |

| 13 | Laser probe ^(40)Ar-^(39)Ar ages of metasomatic K-feldspar from the Hougou gold deposit,northwestern Hebei Province,China显示文摘The Hougou gold deposit in northwestern Hebei is a typical K-metasomatism-related gold deposit hosted by K-altered rocks overprinting alkali intrusive rocks. In order to determine the age and pulse intervals of K-metasomatism in this gold deposit, some metasomatic K-feldspars from K-altered rocks are selected to measure their formation time by laser probe 40Ar-39Ar dating method. The new analyzing data show that these metasomatic K-feldspar formed during 202.6 Ma and 176.7 Ma, and the corresponding K-metasomatism and associated gold mineralization occurred in the early stage of Mesozoic era. The pulse intervals of K-metasomatism in the Hougou area are estimated to be about 4 Ma. | 徐兴旺 张宝林 蔡新平 刘玉林 | 2002 | Science China Earth Sciences2002，45，6： | 5 |
| 14 | U-Pb dating of zircon grains from the ore-bearing plagioclase amphibolite in the Dashuigou Te deposit显示文摘The Dashuigou Te deposit is a unique independent one found in the world, and hosted in the plagioclase amphibolite. The upper intercept age of single zircon from the amphibolite can be considered to be the crystallization age of the source-rock of the amphibolite (tholeiitic basalt), while the lower intercept is nearly consistent with the time of the tectono-thermal event. | Shijin Xu Weizhou Shen Rucheng Wang Jianjun Lu Xiaoming Chen Yuping Lin | 1998 | Chinese Science Bulletin1998，43，17： | 5 |
| 15 | Geochemistry of carbonatites in Maoniuping REE deposit, Sichuan Province, China显示文摘Carbonatites in the Maoniuping REE deposit, Sichuan Province, which are spatially and temporally associated with rare earth mineralization, were emplaced at the time of Himalayan. The rocks are carbonatite-syenite complexes, with the mineral assemblages of calcite-aegirine-acmite- arfvedsonite-mica-orthoclase. The rocks are characterized by the enrichment in incompatible ele-ments, such as Sr, Ba and REE, with C and O isotopic compositions of the 損rimary igneous car-bonatites? relatively high initial 87Sr/86Sr ratios and low e Nd values. All of these suggest that the rocks were derived from the metasomatic enriched mantle. It is demonstrated by geological and geochemical evidence that the mixing of the Himalayan subducting crustal materials with mantle source EM1 is probably the main factor responsible for the formation of carbonatites. The car-bonatite-syenite complexes were generated from liquid immiscibility of CO2-rich alkalic silicate magma, which was derived from partial melting of the metasomatic mantle. | 许成 黄智龙 刘丛强 漆亮 李文博 管涛 | 2003 | Science China Earth Sciences2003，46，3： | 3 |

| 17 | Application of GISto Geo-anomaly-Based Delineation of Mineral Resources显示文摘In this paper, the Dongchuan type copper deposits are taken as an example to illustrate the application of GIS to the geo anomaly based delineation of mineral resources. The following eight steps are listed in this paper to delineate the permissive and preferable ore finding areas: (1) the analysis of favorable prospecting index using linear and planar geo anomalies; (2) the analysis of favorable prospecting index using combined anomalies; (3) the construction of a GIS based spatial model for mineral prognosis; (4) the delineation of the permissive ore finding area; (5) the determination of the synthetic anomalies and numerical range for the prediction of the favorable prospecting areas, and the determination of the weights of these two variables; (6) the superimposition of all the selected anomalies and the construction of the superimposition map; (7) the determination of unifying criterion of favorable prospective areas at various levels, and (8) the delineation of favorable prospective areas. Finally, this paper offers a detailed discussion of the results in the forecasting of Dongchuan type copper deposits. | Chi Shundu Zhao Pengda Li Jianwei The Open Laboratory of Quantitative Prediction and Exploration Assessment of Mineral Resources, Ministry of Land and Resources, Wuhan 430074 | 2000 | Journal of Earth Science2000，19，2： | 2 |
| 18 | Minerogenetic mechanism of Rushan gold deposit, Shandong Province——Evidence of ore-forming fluid and H, O, Sr isotopes显示文摘THE Rushan gold deposit, being of quartz-vein type, is located in biotite monzonitic granite of Kunyushan complex pluton in eastern Shandong, China, and the orebody No. 2 is the largest mono-vein deposits found in China. The gold mineralization can be divided into three stages according to crisscross relations of the various microlodes in the deposit: Ⅰ. pre-ore stage of comb-structured milky-white quartz veins; Ⅱ. main mineralization stage of multi-metal sulphides and siderite-quartz veins; Ⅲ. post-ore stage of mottled cryptocrystalline quartz veins. | Zhai, JP Hu, K Lu, JJ | 1997 | Chinese Science Bulletin1997，42，3： | 1 |
| 19 | Interfacial tension studies between Fe-Cu-Ni sulfide and halo-norilsk basalt slag system显示文摘The interfacial tension of the matte/halo-Norilsk basalt slag systems of FeS-Cu2S-Ni3S2 and FeO-FeS were investigated using the sessile drop technique. The results indicate that interfacial tension decreases with increasing copper and nickel contents in the matte of FeS-Cu2S-Ni3S2 system while it increases with increasing oxygen content in the matte of FeO-FeS system. It is inferred from these results that two conditions are critical for the formation of giant Cu-Ni sulfide deposits. One is that ma-fic-ultramafic parent magma of sulfide deposits should be rich in copper and nickel where due to the low interfacial tension, it is difficult to form sulfide droplet in the early stage of magma evolution. In other words, sulfide liquid conglomeration occurs more difficultly. The other condition is that the magma emplacement should be shallow; and a lot of faults occur in the magma emplacement field. Since oxygen content is high in the environment, interfacial tension is high, which helps sulfide liquid conglomeration and consequently Cu-Ni sulfide deposits form. | Jim Mungall | 2005 | Science China Earth Sciences2005，48，6： | 1 |
