摘要
本文通过对沙拉勿束地区与金矿成矿有关的地层、构造和岩浆岩等方面的深入研究,分析本地区金矿矿床的产生成因和类型,同时明确找矿的标志。矿床成因类型为韧性剪切型矿床,矿体主要赋存于含金石英脉型中,其次赋存于含金破碎带和含金糜棱岩中,石英脉(硅化)、绢云母化、绿泥石化是寻找金矿的最直观标志。
Through in-depth study of the strata, structures and magmatic rocks related to the gold mineralization in the salad area, this paper analyzes the causes and types of the gold deposits in the region, and makes clear the marks for the prospecting. The genetic type of the deposit is a ductile shear type deposit. The ore body mainly occurs in the gold bearing quartz vein type, followed by gold bearing and gold mylonite. Quartz vein（silicification）, sericite and green mud petrifaction are the most visual signs for finding gold deposits.
