摘要:
应用均一法、激光拉曼显微探针法研究驼路沟钴矿床的流体包裹体,发现其包裹体类型多样,以气液两相 包裹体和富二氧化碳包裹体为主,测得均一温度为220℃～300℃,众值为275℃,成矿流体形成于中低温环 境。通过对其他热力学参数计算,确定出驼路沟钴矿床成矿流体具有中低盐度、低密度、弱还原-还原性的特 点。包裹体气、液相成分分析表明其与现代海底热液沉积物的流体成分类似,进一步佐证了驼路沟钴矿床为热 水喷流沉积成因。
Abstract:
The fluid inclusions of Tuolugou cobalt deposit are studied by Homogenization Method and Laser Raman Method. The systematical study shows that the type of fluid inclusions is multiplicity, mainly including two types: two phase liquid-vapor inclusions and abundant CO2inclusions. The homogenization temperatures of fluid inclusions ranges from 220℃ to 300℃(frequent 275℃), which indicates that the ore-forming fluids were formed under low-middle temperature condition. According to calculating other thermodynamic parameters, the ore-forming fluids in ores are characteristic of low-middle salinity, low density and weak deoxidize-deoxidize. Finally, based on the analysis of liquid-vapor phase compositions of inclusions, the compositions are similar to submarine hydrothermal, and it puts forward the new proof about the metallogeny of submarine sedimentary exhalation of ore deposit.
