摘要
云南永胜县宝坪铜矿矿体呈层状、似层状、透镜状赋存于上二叠统黑泥哨组(P3h)基性火山岩及火山碎屑沉积岩中,而且在火山碎屑沉积岩中出现的的铜矿体规模较大。该铜矿床的形成与晚二叠世火山喷发关系密切,火山成矿物质是铜矿的主要来源。黑泥哨组(P3h)及地表孔雀石矿化均是重要的找矿标志。
The orebody of Baoping Cu deposit in Yongsheng,Yunnan is bedded,stratoid,lenticular in Upper Permian Heinishao Formation(P3h)basic volcanic rock and volcanic clastic sedimentary rock,and the Cu orebody in the volcanic clastic sedimentary rock is larger than the others.The formation of this Cu deposit is in close relation to the volcanic eruption in Late Permian.The main source of Cu deposit is the volcanic metallogenesis material.Heinishao Formation(P3h)and malachite are the important prospecting criteria.
