云南省东川矿区白沙包铜矿地质特征及找矿方向

白沙包铜矿赋存于震旦系陡山沱组地层中、下部,为陆源沉积建造型铜矿。文章从矿床地质特征、成矿地质背景、成矿物质来源、,成矿环境条件和成矿作用等进行了分析研究,提出该区存在二个局限沉积盆地赋存含矿地层陡山沱组,且分布面积大,具有较大找矿潜力,并指出了找矿方向。

Geological characteristics and ore prospecting direction of Baishabao copper deposit in Dongchuan mining area of Yunnan

Baishabao copper deposit is located in the medium and lower part of Doushantuo formation in Sinian system,and it is a copper deposit of terrigenous sedimentary formation.After analyzing this area in terms of metallogenic geological background,metallogenic material source,metallogenic environment and conditions and metallogenesis,this paper proposes that there are two restricted sedimentary basins which are located in Doushantuo formation of ore-bearing strata and both of the basins are widely distributed.The results of the study not only show that the potential of prospecting in the area is relatively outstanding,but also point out the prospecting direction.
