| 1 | Geochemical characteristics of upper Sinian Dengying dolomite at northern Yangtze platform: implication for Pb-Zn metallogenesis显示文摘1 Introduction and geological setting Several Pb-Zn ore deposits(i.e.,Mayuan Pb-Zn deposit)occurring inthe upper Sinian Dengying dolomitesin northern Yangtze platform have been discovered in recent years,interesting research | CHEN Baoyun LI Rongxi YU Jinjie LIU Shuaijie ZHANG Shaoni | 2017 | Acta Geologica Sinica(English Edition)2017，91，S1： | 0 |
| 2 | Genesis and mineralization of gold-bearing quartz veins in the Xiao Qinling area,central China显示文摘Gold-bearing quartz veins of the Taihua Group consisting of Archean metavolcanic rocks are a main gold deposit type in the Xiao Qinling area,one of the three biggest gold production areas in China.The quartz veins experienced strong alteration characterized by a typical mesothermal hydrothermal altered mineral assemblage.The grade of gold is affected by the contents of sulphides,e.g.galena,pyrite and chalcopyrite.Results of minor elements analysis for the of gold-bearing quartz veins indicate higher contents of Au and high contents of Ag,Pb,Cu,Cd,W,and Mo.Abundant fluid inclusions were found in the gold-bearing quartz veins.Three types of fluid inclusions were identified:(1) aqueous inclusions;(2) CO 2-bearing inclusions;and(3) daughter crystal-bearing fluid inclusions.Homogenization temperatures ranged from 110 to 670℃ with low and high peaks appearing at 160 180℃ and 280 300℃,respectively.The salinity of aqueous inclusions varies between 1.8 wt% and 38.2 wt% NaCl.The homogenization temperature and salinity show a positive correlation.The H and O isotopes of fluid inclusions in the gold-bearing quartz veins indicate that magmatic solution and metamorphic hydrothermal solution,together with meteoric water,were involved in the formation of gold-bearing fluid.Mesozoic magma activities related to granite intrusions should be the main source of CO 2 fluid with higher temperature and salinity. | LIANG Jiwei LI Rongxi ZHANG Shaoni CHEN Baoyun DUAN Lizhi Pierre Thibault | 2012 | Chinese Journal Of Geochemistry2012，31，4： | 0 |
