摘要
In Tianzhu- Jinping area,the ore- bearing formation,metallogenic material source and metallogenesis of gold deposit in shallow metamorphic rock series are studied. It’s thought the ore- bearing formation mainly is terrigenous clastic,has abundant basaltic volcanic clastic and formed in oxidizing environment.By compare pure quartz vein,gold- bearing quartz vein and arsenopyrite- bearing quartz vein,it’s known the main metallogenic elements has concentrated before wall rock extraction,the source may be deep. The gold- bearing quartz vein elements shows two metallogenic sources: deep material and wall rock. The Kk and lognormal distribution curve of hydrothermal mineralization element shows ore concentration happened in every mine area. According to mineral deposit geochemistry and field information,it inferred the alter mineralization has 3 types: gold mineralization,arsenopyrite mineralization and lead- zinc mineralization,the relations is accompanying,stacking or independent.
