大冲金银矿床位于桂东南云开区五个金（银）矿集中区之一的石窝（石科）变质岩地区，产在叠加有早期基底剥离断层的燕山期脆性断层中，最终定位的成矿热液主要来自燕山期的花岗斑岩类岩浆。金银矿有用组分中，部分银以银黝铜矿形式赋存，金和另一部分银主要以碲化物形式赋存。文章还从岩石矿物学的角度出发，对该区的成矿地质条件参数进行估算。

The Dachong gold-silver deposit lyes in Shiwo metamophic rocks area, one of five important gold-silver ores collctive areas in Yun Kai province of Guangxi, occors in the brittle shear zones superposing on early denudational fault belt. The Yanshannian porphyritic magma provided most part of hydrothermal fluids for the formation of the deposit. In the deposit ,the Au occors mainly in Telluride while the Ag occors partially in Freibergite, and partially takes the shape of Telluride with the Au. Some geochemical parameters of the deposit also have been estimated according to the petrographic analysis.
