黄沙坪多金属矿床流体地球化学研究进展
|
摘要
黄沙坪铅锌矿床是南岭钨锡钼铋铅锌多金属成矿带的一个典型矿床,是湘南地区最大的铅锌多金属矿床。通过对该矿床前人研究资料的收集和整理,对矿床流体地球化学研究中的重要进展进行归纳总结。矿床不同矿物中发育六类包裹体,分别为纯气相、纯液相、富气相气液两相、富液相气液两相、含CO_2三相、含子矿物三相包裹体。按照矽卡岩不同矿化类型成矿流体呈现矽卡岩阶段分异作用和硫化物阶段混合作用为主的演化特征;是典型的还原性矽卡岩型铜多金属矿床。
The Huangshaping lead-zinc deposit is a typical deposit of the Nanling W-Sn-Mo-Bi-Cu-Pb-Zn polymetallic metallogenic belt and the largest lead-zinc polymetallic deposit in southern Hunan. Based on the collection and collation summarized the important progress in the geochemical study of predecessors' research in Huangshaping deposit. Dividing six kinds of inclusions in different mineralshosted, which are pure gas phase, pure liquid phase, gas-rich gas-liquid two-phase, liquid-phase gas-liquid two-phase, CO_2 three-phase,and three-phase inclusions containing minerals. According to the different mineralization types of skarn, the ore-forming fluids are characterized by the differentiation of skarn stage and the mixing of sulfide phases. As a typical reduced skarn type copper polymetallic deposit.
