论砂岩铜矿金属矿物分带及其在找矿中的应用

Discussion of the Zonation of Metallic Minerals in Sandstone Copper Deposits and Its Application to Prospecting

本文以后生成因观点,阐明砂岩铜矿金属矿物分带和特征及其与地下水面、下伏煤系地层、上覆泥岩盖层剥蚀残留程度的成因联系,进而将砂岩铜矿的金属矿物分带划分为开放型和封闭型两种基本类型,并阐述了其对找矿勘探的具体应用。

According to the point of view of the epigenetic origin, this paper clarifies the zonations and characteristics of the metallic minerals in sandstone copper deposits and the original relation among the zonations and characteristics, water table, underlying coal measures and the destraction and retention of overlying argillacous rocks. The zonations can been classfied into two basic types - openning and confining, the application of which to prospecting is discussed too.
