栾川三道庄特大型钼钨矿床位于华北地台南缘与秦岭褶皱系接合部位的东段.在讨论成矿地质背景基础上,对矿石物质成分进行了研究.在不同矿石类型中,矿物种属和含量变化较大.按各种矿石类型的矿物成分和形成阶段的不同进行了划分,对比分析认为矿石中主要有益组分为Mo、W,S、Re可综合利用、回收,并对各种元素的赋存状态也进行了分析.根据矿化特征、矿物共生组合及生成先后,成矿作用可分为四个阶段.今后的找矿工作中,对于相类似的矿床有一定的借鉴和指导意义.

The Sandaozhuang superlarge Mo-W ore deposit of Luanchuan is located in the eastern part of the conjunction between the southern margin of the North China Platform and the Qinling folded system. Based on a discussion on the metallogenic geological setting, the authors studied the ore material composition. Mineral species and content vary remarkably in different types of ores. Division and comparison were made for mineral constituents of various ore types according to their components and formation stages. The major useful components seem to be Mo and W. In addition, S and Re can be retrieved for comprehensive utilization. The modes of occurrence of various elements were also analyzed. According to mineralization characteristics, mineral association and formation sequence, the ore-forming process can be divided into three phases composed of six stages. The results obtained are of reference and guiding significance in search for similar ore deposits.
