| 2 | Rb-Sr isotopic dating of sphalerite from the giant Huize Zn-Pb ore field, Yunnan Province, Southwestern China显示文摘The giant Huize Zn-Pb ore field in Yunnan Province, southwestern China, comprises the Qilinchang and Kuangshanchang deposits. The deposits are large in scale (more than 5 Mt of Zn and Pb) and high in grade (average grade of total Zn and Pb is 30%). Reported in this paper are the results of Rb-Sr isotopic dating of sphalerite from this ore field. Two precise ages (223.5±3.9 Ma and 226±6.4 Ma) have been obtained from two isochrons. These two ages are close to the reported ages of native copper mineralizations related to the Emeishan flood basalts in this region, which are 226 Ma to 228 Ma. Previous studies showed that the magnitude of uplift resultant from the Emeishan flood basalts is greater than 1000 m, indicating that the Kuangshanchang and Qilinchang deposits were formed during the same geological event and originated by fluid migration during uplifting resultant from the Emeishan flood basalts. | LI Wenbo | 2009 | Chinese Journal Of Geochemistry2009，28，1： | 25 |

| 4 | A study on the mixing proportion in groundwater samples by using Piper diagram and Phreeqc model显示文摘Piper (1944) diagram has been the basis for several important interpretations of the hydrogeochemical data. As seen in this diagram, most natural waters contain relatively few dissolved constituents, with cations (metals or bases) and anions (acid radicles) in chemical equilibrium with one another. Apart from the facies representation, the composition of the mixed sample can be identified in terms of the composition of the parental solution. To bring out this advantage of the Piper diagram, a study was conducted in the Kalpakkam region of Tamilnadu, South India. By taking the geology and water table into consideration, two sample locations were selected as parent solution and third one as the mixture sample. All three samples were analyzed for calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), chloride (Cl), sulphate (SO4) and phosphate (PO4) by Ion Chromatograph (Metrohm IC 861). HCO3 was determined by volumetric titration. The Piper diagram shows that parent solutions clustered towards Na-Mg-Ca-HCO3-Cl and Na-HCO3 facies, and the mixing sample belongs to Na-Mg-HCO3 facies. Phreeqc interac-tive (Ver 2.8) along with the original composition of the mixture sample was used to correlate the mixing proportion identified by the Piper diagram. | Karmegam U. Chidambaram S.

| 5 | Age, Mechanism and Direction of East Qinling-Dabieshan Lithosphere Delamination Petrological Evidence and Stipulation显示文摘Through studies of P\|T\|t paths and decompressive retrograde metamorphic textures of metamorphic rocks in the East Qinling\|Dabieshan region, the authors determined the Mesozoic crust rapid uplifting age, and then inferred that in the East Qinling\|Dabieshan region lithosphere delamination occurred from T\-3 to J\-1. The Yanshanian granites produced by delamination are developed well in the East Qinling\|Dabieshan region. But due to the Gondwana plate effect, magmatism in the region caused by delamination lagged until J\-3 when the northern Tibet terrane and the Eurasian plate completely amalgamated. Additionally, due to western Pacific plate subducting underneath the Eurasian plate, in the East Qinling\|Dabieshan region the stress state was transformed from compression to extension. So in the region from J\-3 to K\-2 magmatism was most intensive, and liberalization was also relatively strong. Geophysical data reflect that in the East Qinling\|Dabieshan region the asthenosphere rose to the shallow level, the Moho is flat with no mountain root, and the crustal thickness is less than 40 km on average. These features agree with those of collisional orogenes in which delamination has occurred. Through contrasting differences in surface and interior depth between east and west Qinling we believe that delamination proceeded from east to west. | 李超 陈衍景 何顺东 | 2001 | Chinese Journal Of Geochemistry2001，20，1： | 19 |
| 6 | Late Proterozoic Colisional Orogen and Geosuture in Southeastern China:Petrological Evidence显示文摘The Jiangshan-Shaoxing fracture belt(JSFB)is a Late Proterozoic geosuture due to island arc-continent collision in South China,The Cathaysian Block(CT),lying on the southeast side of JSFB,is composed of green schist-amphibolite complexes in the form of a series of tectonic flakes. On the northwest side of JSFB,which is located in the border area of Zheijiang,Jiangxi and Ahhhi provinces(abbreviated as ZJP-JXP-AHP),are distrbuted and ophiolite suite and other rocks,constituting the Jiangnan ancient island arc(JN)on the southeast margin of the Yangtze Block(YZ).The collision between JN and CT at-0.9Ga ago led to the folding of JN.followed by the intrusion(-0.9-0.8Ga ago)of many dioritic and ultramafic stitching plutons along the fracture belt.As a result,the basic Precambrian tectonic framework of southeastern China was shaped. | 周新民 朱云鹤 | 1993 | Chinese Journal Of Geochemistry1993，12，3： | 18 |
| 7 | Petrological and Mineralogical Study of Enclaves in Plutons in the Typical Mining Districts of Tongling, Anhui and Its Bearing on the Process of Magmatism Metallogeny显示文摘Two types of enclaves occur in magmatic plutons in Tongling, Anhui. Enclaves of the first type are residuals of metamorphic rocks of high amphibolite facies, and those of the other type are magmatic rocks ranging from monzonitic to dioritic in composition. A combined petrological and mineralogical study has been carried out on the two types of enclaves in order to estimate their forming conditions and analyze their relations to their hosts, so as to have an insight into the material sources of magmatic rocks and associated mineral deposits and give a clue to better understanding the mechanism of magmatism metallogeny. This leads us to propose a new metallogenic model for strata bound skarn type ore deposits associated with a syntectic type of magmatic rocks. The new model can be simply summarized as partial melting of old metamorphic basement rocks at depth and accumulating, differentiating and positioning of magmas to form deep level and shallow level magma chambers, followed by mixing of different magmas associated with their crypto explosion, migration of gas bearing ore fluids and precipitation of metals in fluids within the magmas. | 杜杨松 | 1999 | Chinese Journal Of Geochemistry1999，18，3： | 18 |
| 8 | Pollution of organic compounds and heavy metals in a coal gangue dump of the Gequan Coal Mine, China显示文摘Samples around a coal gangue dump of the Gequan Coal Mine were collected in April 2009. GC (gas chromatography) and GC/MS (gas chromatography/mass spectrometry) were employed to analyze the composition of organic matter in the samples. ICP-MS (inductively coupled plasma mass spectrometry) was used to determine the concentrations of heavy metals. The contents of organic extracts are within the range of 140-750 mg/kg. Alkand aro-ratios are relatively high. Compared to those of the background sample (GQ13 ), the contents of saturated hydrocarbon compounds in all the samples are relatively high. The contents of polycyclic aromatic hydrocarbons (PAHs) are relatively high with the distance getting closer to the coal gangue dump. These indicate that organic matter in the samples is from coal particles of the coal gangue dump. The distributions of heavy metals are very similar: the contents decrease with distance from the dump, which indicates that the harmful heavy metals from the coal gangue dump have polluted as thick as at least 500 m. | FAN Jingsen SUN Yuzhuang LI Xinyu ZHAO Cunliang TIAN Duanxin SHAO Longyi WANG Jinxi | 2013 | Chinese Journal Of Geochemistry2013，32，3： | 18 |
| 9 | Isotopic compositional Characteristics of Terrigenous Natural Gases in China显示文摘The C and H isotopic compositions of the methane in more than 160 gas samples from 10 basins in China are presented in this paper.The natural gases are classified as four types: biogenic gas ,bio-thermocatalytic transitional gas, gas associated with condensate oil ,and coal-type gas. The isotopic compositions of these gases closely related to the depositional basins, the types of organic matter,the stages of thermal evolution and the genetic characteristics of different gas reservoirs.Studies of the C and H isotopic compositions of terrigenous natural gases will provide valua-ble information on the prospecting and development of natural gases of different genetic types. | 沈平 徐永昌 | 1993 | Chinese Journal Of Geochemistry1993，12，1： | 17 |
| 10 | Characteristics of rare-earth elements (REE),strontium and neodymium isotopes in hydrothermal fluorites from the Bailashui tin deposit in the Furong ore field,southern Hunan Province,China显示文摘In this paper the authors present the REE concentrations and Sr and Nd isotopic compositions of fluorites from the Bailashui tin deposit of the Furong ore field,southern Hunan Province. The results showed that the total amount of REE in fluorites is usually low,ranging from 0.705 to 8.785 μg/g with the chondrite-normalized REE dis-tribution patterns similar to those of the Qitianling granites in the study area,characterized by LREE-enrichment patterns with pronounced negative Eu anomalies. The fluorites vary in Sr isotopic composition within the range of 0.7083-0.7091,the values are lower than those of the granites and higher than those of the host carbonate rocks in this area. The εNd(t) values of fluorites vary between -9.4 and +10.3,revealing that both the crust-and mantle-source materials were involved in the ore-forming hydrothermal fluids. Combined with previous studies on this ore deposit,the Bailashui tin deposit is temporally and spatially closely related with granitic magmatism in this area. The hydro-thermal fluorites are the product of fluid/rock interactions between granitic magmatic hydrothermal fluid and marine carbonate rocks. The REE and F in the ore-forming fluid were derived from the granites,whereas Sr in the ore-forming fluid came mainly from the granitic magmatic hydrothermal fluid and marine carbonate rocks,although variations in Sr isotopic composition cannot be explained by a simple mixture of these two end-members. Evidence demonstrated that the ore-forming fluids are of crustal-mantle mixing origin,but that the fluids were probably in-completely homogenized and this may be caused by inhomogeneous mixing of the fluids of different sources. | YUAN Shunda PENG Jiantang HU Ruizhong BI Xianwu QI Liang LI Zhaoli LI Xiaomin SHUANG Yan | 2008 | Chinese Journal Of Geochemistry2008，27，4： | 16 |
| 11 | Sulfur isotopic composition of the Tianqiao Pb-Zn ore deposit,Northwest Guizhou Province,China:Implications for the source of sulfur in the ore-forming fluids显示文摘The Tianqiao Pb-Zn ore deposit of Guizhou Province, China, is located in the mid-east of the Sichuan-Yunnan-Guizhou Pb-Zn-Ag multi-metallic mineralization area, which is representative of the Pb-Zn ore de-posits in this area. It consists of three main orebodies, whose Pb+Zn reserves are more than 0.2 million ton. This paper analyzes the sulfur isotopic composition of these orebodies. The data show that the ore minerals (galena, sphalerite, pyrite) in these orebodies are enriched in heavy sulfur, with δ34SV-CDT values varying between 8.35‰ and 14.44‰, i.e. the δ34SV-CDT values of pyrite are between 12.81‰ and 14.44‰, the mean value is 13.40‰; the δ34SV-CDT values of sphalerite are range from 10.87‰ to 14.00‰, the mean value is 12.53‰; the δ34SV-CDT values of galena are range from 8.35‰ to 9.83‰, the mean value is 8.84‰, and they have the feature of δ34Spyrite>δ34Ssphalerite>δ34Sgalena, which indicates the sulfur isotope in ore-forming fluids has attained equilibrium. The δ34S V-CDT values of the deposit are close to those of sulfates from carbonate strata of different ages in the ore-field (15‰), which suggests that the sulfur in the ore-forming fluids should be derived from the thermo-chemical sulfate reduction of sulfates from the sedimentary strata. | ZHOU Jiaxi HUANG Zhilong ZHOU Guofu LI Xiaobiao DING Wei BAO Guangping | 2010 | Chinese Journal Of Geochemistry2010，29，3： | 16 |
| 12 | Study on Secondary Migration of Hydrocarbons in Tazhong Area of Tarim Basin in Terms of Carbazole Compounds显示文摘Fractionated carbazoles have been detected for the first time in crude oils from the Tazhong area of the Tarim Basin, and these nitrogen compounds were successfully utilized in the study of petroleum migration. Alkylcarbazoles are quite abundant in all the samples analyzed; small amounts of benzocarbazoles were detected only in some of the samples, and dibenzocarbazoles were not found in the oils. Based on the distributions of G1, G2 and G3 types of C\-2\|alkylcarbazoles, the ratio of C\-3\|/C\-2\|carbazoles and the relative concentrations of alkylcarbazole and alkylbenzocarbazole, oils in the Carboniferous C\-Ⅲ reservoir in the Tazhong uplift are thought to have laterally migrated to the high level of Tazhong structure No. 4 from both northwest and southeast. The study here also shows that oils in the area may have undergone long\|distance migration. | 刘洛夫 康永尚 等 | 1999 | Chinese Journal Of Geochemistry1999，18，2： | 15 |
| 13 | Environmental Geochemistry of Heavy Metal Contaminants in Soil and Stream Sediment in Panzhihua Mining and Smelting Area,Southwestern China显示文摘Mining and smelting activities are the main causes for the in creasing pollution of heavy metals in soil, water body and stream sediment. An e nvironmental geochemical investigation was carried out in and around the Panzhih ua mining and smelting area to determine the extent of chemical contamination in soil and sediment. The main objective of this study was to investigate the envi ronmental geochemistry of Ti, V, Cr, Mn, Cu, Pb, Zn and As in soil and sediment and to assess the degree of pollution in the study area. The data of heavy metal concentrations reveal that soils and sediments in the area have been slightly c ontaminated. Geochemical maps of I\-\{geo\} of each heavy metal show that the co ntaminated sites are located in V-Ti-magnetite sloping and smelting, gangues d am. The pollution sources of the selected elements come mainly from dusts result ant from mining activities and other three-waste-effluents. The area needs to be monitored regularly for trace metal, especially heavy metal enrichment. | 滕彦国 庹先国 倪师军 张成江 徐争启 | 2003 | Chinese Journal Of Geochemistry2003，22，3： | 15 |
| 14 | Research on thermal shock resistance of mullite-bauxite-silicon carbide castable refractory显示文摘Effects of different silicon carbide contents on thermal shock resistance properties of mullite-bauxite castable refractory were analyzed respectively by taking the mullite,bauxite as main raw materials and taking calcium aluminate cement as a binding system.After 24 h curing in mould and another 24 h curing at 110℃ after demoulding,the samples were heated at 1000,1300 and 1500℃for 3 h in air,respectively.The bulk density,thermal expansion coefficient and thermal shock resistance were examined.The results showed that there was a great effect of content of SiC on bulk density,thermal expansion coefficient and thermal shock resistance of mullite-bauxite castable.Under the experimental conditions,the castable performed the best thermal shock resistance when w(SiC)=5%-10%. | Nobuaki Chiyoda | 2012 | Chinese Journal Of Geochemistry2012，31，2： | 15 |
| 15 | Effect of Bacillus mucilaginosus on weathering of phosphorite and a preliminary analysis of bacterial proteins显示文摘The authors investigated the effect of Bacillus mucilaginosus on weathering of phosphorite. Analysis of different proteins was of significance in exploring the molecular biological mechanism in the bacterial weathering process. The concrete methods are described as follows: Mineral powder was put into liquid culture medium and B. mucilaginosus was incubated in the medium. The control (group) had no mineral powder in the medium. The treatments and controls were cultured simultaneously under the same condition. In a few days, the supernatant was filtrated, the main cations (Ca2+, Mg2+, Na+, Mn2+, Al3+, Fe3+, K+) were measured by ICP-OES, and the contents of water soluble phosphorus (Pws) and silicon (Siws) were determined by colorimetry. The residual solid was weighed on the filter paper, followed by digestion with concentrated HNO3. The concentrations of the main cations and Pws, Siws in the digest liquid were measured by using the method mentioned above. After the supernatant was centrifuged, the precipitation was used to analyze the protein differences between the treatment groups and the control groups by 2-dimentional gel electrophoresis (2-DE). The experimental results showed that apatite and quartz were partially weathered, but kaolinite was dissolved completely. The population of bacteria increased when mineral powder was added in the liquid medium. Software analysis and comparison of the 2-DE pictures of bacterial proteins revealed 1134 visible protein spots in the treatment group, and 729 visible protein spots in the control group. To compare the bacterial protein expression contents of the treatment group with those of the control group, there were 496 different protein spots, including 214 protein spots which indicated that the protein contents increased, 75 protein spots were indicative of a decrease, and 207 proteins were newly synthesized. It is proposed that the increased bacterial contents may be related to some protein expression and activation after the input of mineral powder. Newly synthesized proteins, the increase of expression contents and the reduction of proteins may be connected with bacterial metabolic regulations, cell activation and signal transmission. | CHEN Shu LIAN Bin LIU Congqiang | 2008 | Chinese Journal Of Geochemistry2008，27，2： | 14 |
| 16 | The distribution characteristics of heavy metals in Guiyang urban soils显示文摘Guiyang is located in southwestern China,which is a famous tourism city,and is awarded the title of'the Summer Capital of China'.A study on heavy metals in Guiyang urban soils was conducted.The results showed that the concentrations of Cd,Cu,Ni,Pb and Zn in Guiyang urban soils are significantly higher than their background values and Cu,Zn and Pb in Guiyang soils are accumulated seriously.The distribution characteristics of heavy metals in 3 districts are described as follows:the level of heavy metals in soils follows the order of Nanming District> Yunyan District>Xiaohe District.The spatial distribution of metals in urban soils of Guiyang shows that the level of metals in the central and eastern parts of Guiyang is relatively high,and its characteristics are attributed to the influence of commercial activities,heavy traffic and industrial emission.Compared with some other cities in China,Guiyang is characterized by relatively high accumulation level of Cd,Cu,and Zn in its soils. | LI Xiaoyan CAO Yijin QI Le SHU Fu | 2012 | Chinese Journal Of Geochemistry2012，31，2： | 14 |
| 17 | Calcified roasting-acid leaching process of vanadium from low-grade vanadium-containing stone coal显示文摘The low-grade vanadium-containing stone coal used in this experiment was collected from Wuxi Country, Chongqing City, China. The experiment focused on the vanadium recovery from roasted residue through optimizing the process conditions of an effective and environmentally-friendly technology, named calcified roasting-sulfuric acid leaching technology. By single-factor experiments and orthogonal experiments, the effects of roasting temperature, roasting time, sulfuric acid concentration and leaching time on the leaching ratio of vanadium were analyzed. The results showed that the leaching ratio of vanadium reached 85.5% under the proper technological conditions of roasting temperature=950℃, roasting time=4 h, 40% concentration of sulfuric acid and leaching time=6 h. | WANG Taiying XU Longjun LIU Chenlun ZHANG Zhaodi | 2014 | Chinese Journal Of Geochemistry2014，33，2： | 14 |
| 18 | Geochemical Enrichment and Mineralization of Indium显示文摘Indium occurs in a very dispersed manner in nature with enrichment of economic Interest rarely known. The highly dispersed nature of indium, among several other elements, hasfor a long time retarded our understanding of the regularities that control their mineralization,which in turn has hindered exploitation and application of these elements. Recent studies ofours show that no significant enrichment of indiurn can be recognized in various types of Pb-Znsulphide deposits as well as in deposits of copper, iron and manganese. Indium concentrationsin ores of these deposits are generally below 10×10-6. In contrast, however, indium is foundto be enriched to a significant extent in cassiterite-sulphide deposits and some tin-rich Pb-Znpolymetallic deposits. The average content of indium in these deposits can be over 100×10-6,and more than 90% of it is concentrated in sphalerite. Generally, these deposits may be considered as large paragenic deceits for indium and, therefore, there must be some regularitiesthat govern the geochemical enrichment of the so-called 'dispersed element' indium. | 张乾 战新志 潘家永 邵树勋 | 1998 | Chinese Journal Of Geochemistry1998，17，3： | 14 |
| 19 | Application of Pb isotopic tracing technique to constraining the source of Pb in the West Lake Longjing tea显示文摘This paper dealt with the Pb contents and Pb isotopic composition of the West Lake Longjing tea. The results showed that in the tea leaves, from young leaf →old leaf →tea limb, the Pb contents tend to increase gradu-ally from 1.63 →4.84 →6.07×10-6, wich revealed that the Pb was accumulated gradually in the tea. After cleaned, the Pb contents of tea leaves were significantly reduced. This indicated that the deposits on the surface of tea leaves made a great contributuion to Pb contents. The survey results for soils in the relevant tea gardens showed that soil from the Longjing tea garden has higher Pb contents, with an average level of 49.6×10-6, two times those of common soils (24×10-6) in China. Results of the systematic analysis for tea, tea garden soil and the samples with the relevant background of the Pb isotopic composition displayed that the Pb isotopic ratio of tea is 206Pb/207Pb=1.164±0.005 (2σ). The ratio of 206Pb/207Pb for the soil gradually decreased from residue phase, soil dilute acid extract phase, and then to urban topsoil, i.e., 1.175 →1.171 →1.170. The 208Pb/(206Pb+207Pb) ratios also show a similar variation trend. 206Pb/207Pb ratios in the samples with the relevant background were: vehicle exhaust, 1.124; coal-combustion, 1.156; atmosphere, 1.168; and water, 1.166. Comparative studies have shown that Pb pollution is popular in the environ-mental media (soil, atmosphere, water) in Hangzhou. With the aggravation of Pb pollution, the Pb isotopic composi-tion gradually changed from the natural background (soil residues) to the direction of automobile exhaust. This phe-nomenon could illustrate that the pollution source was the vehicle exhaust, while the coal-combustion contributed little to environmental pollution in Hangzhou. The Pb of the Longjing tea came mostly from soluble phase Pb in the polluted soil. Moreover, secondary pollution was caused by vehicle exhaust. | LU Yuanfa YANG Hongmei MA Liyan CHEN Xiqing WANG Qunying | 2011 | Chinese Journal Of Geochemistry2011，30，4： | 13 |
| 20 | Geochronology of a surface core in the northern basin of Lake Qinghai: Evidence from ^(210)Pb and ^(137)Cs radionuclides显示文摘The radioactivities of 210Pb and 137Cs have been measured to estimate the dates of the sediments of a surface core (QH0407-C-2) in the northern basin of Lake Qinghai. The sedimentation rate derived from 210Pb radioactivity correlates well with that inferred from (137)Cs radioactivity. The dates calculated from depth sedimentation rate (cm/a) are similar to those derived from mass accumulation rate (g·cm-2·a-1) between 0-5 cm, but are significantly different below 5 cm, which has been ascribed to the compaction of surface sediments during early diagenesis. The dates derived from mass accumulation rate are consistent with those calculated from the AMS 14C dating model. The precipitation-controlled indices based on the chronology data derived from mass accumulation rate are similar in trends to the precipitation reconstructed from tree rings in adjacent region, which further verifies the reliability of the geochronology data. | 徐海 艾莉 谭亮成 安芷生 | 2006 | Chinese Journal Of Geochemistry2006，25，4： | 12 |
