| 摘 要： | 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,对矿床地质特征进行了研究。矿体形态、产状受岩性、构造控制较为明显,分布范围、产状与钙硅酸角岩、矽卡岩的分布范围、产状相一致,受箱状背斜控制;通过成矿阶段划分、成矿温度测定以及同位素特征的分析,说明三道庄钼钨矿床无论在空间上、时间上、成因上均与深部同熔型花岗岩浆有关,成矿物质来源除主要来自深部同熔型岩浆外,在矿液运移过程中可能有少部分地壳物质的加入。同时指出了找矿标志,对以后的找矿工作有一定的指导意义。

| Abstract: | Luanchang Sandaozhang super large molybdenum-tungsten ore deposit locates in eastern section of junction between the North China platform south rim and the Qinling fold system.Its geological feature is studied based on the geological background.The occurrence of orebody is obviously limited by lithology and structure,and consistent with the lime hornfels and skarn,as a van fold.Through dividing stage and temperature of ore-forming and analyzing the isotope feature,indicate the space,time and genesis of the ... |
