摘要
赤峰西部索虎沟金矿床是近年来新发现的一种蚀变岩型金矿床 ,矿体产于燕山期铭山花岗岩与上侏罗统安山质火山岩地层的断层接触带内。本次研究在野外踏勘基础上 ,通过对采集的样品进行系统的光薄片观测和显微照相 ,初步确定了矿石的矿物共生组合和金银矿物的赋存状态、粒度等特征 ;用扫描电镜、电子探针测定了金银矿物的成分 ,从而对矿体特征有了新的认识。该研究成果将对进一步认识该矿床的成因和规律具有一定的指导意义。
Suohugou gold deposit is an tectonic altered rock type deposit discovered in recent years in west Chifeng. The deposit occurs in cataclastic zone between Yanshan phase Mingshan granite and the andesite volcanic rock stratum belongs to Jurassic. On the basis of field reconnaissance, the light slices was studied and micrography was conducted, the combination of paragentic minerals are confirmed as well as the occurrence state and granularity of gold and silver in the ores. The ingredients of gold and silver are identified with EPMA and SEM EDS, showing us some new features of the orebody. This research achievement will be useful for further understanding of geological features of Suohugou gold deposit.
