| 摘 要： | 东山岔金钼矿床位于王小堡-线金厂-井家沟金成矿带上.目前已发现多处小型金矿床及矿点.金矿体主要赋存于云英岩化紫苏花岗质片麻岩及云英岩中,受断裂构造控制明显.矿化类型有金-钼矿化和金矿化.矿床找矿标志主要包括矿体的原生露头、近矿围岩蚀变、矿物地球化学及地球物理特征方面.通过对区内已知矿床的矿体形态、矿石组成、结构构造、围岩蚀变等进行对比和分析,认为该区成矿物质主要来源于含矿岩体和地层,矿床成因应属与中酸性侵入岩密切相关的中低温热液型金钼矿床.

| Abstract: | The Dongshancha gold-molybdenum deposit is located in the Wangxiaopu-Xianjinchang-Jingjiagou gold metallogenic belt,where quite a few small-sized gold deposits and occurrences have been found.The orebodies occur mainly in greisen altered charnockitic gneiss and greisen,obviously controlled by faults.The prospecting indicators involve primary outcrop of orebody,wallrock alteration,mineral geochemistry and geophysical features.Based on comparative analysis on the ore bodies,ore composition,structure and wallrock alteration of known deposits in the area,it is believed that the ore-forming matters are derived mainly from ore-bearing intrusive rocks and strata.Genetically,the deposit belongs to meso-epithermal type closely related to acid-intermediate intrusive rocks. |
