新疆东天山东戈壁钼矿矿床地质和地球化学特征被引量：1: 2013年; 新疆东天山东戈壁钼矿床是迄今为止在我国东天山找到的最大规模的钼矿床，钼矿资源量超过5×105t。该矿床赋存于花岗斑岩外接触带中，矿石矿物以辉钼矿、黄铁矿为主，围岩蚀变以硅化、钾化、黄铁矿化、电气石化、碳酸盐化和萤石化为特征。其成矿作用可以划分为成矿期和成矿期后两个阶段，成矿温度为140℃～380℃，盐度为0．88—21．33wt％NaCl，成矿深度为1．76～2．87km，指示东戈壁钼矿为中低温、中低盐度的浅成矿床。对主要钼矿体8件辉钼矿样品进行Re—Os同位素分析获得的等时线年龄为234．3±1．6Ma，表明该矿床的成矿时代为印支期。东戈壁钼矿床形成时代的厘定对于提高该矿床的理论研究水平和指导该区隐伏金属矿床的找矿勘查工作均具有重要意义。; 杨晓梅王忠梅丁嘉鑫韩春明; 关键词：RE-OS同位素年龄辉钼矿
