摘　　要：豫西南二郎坪地块位于北秦岭构造带南缘,介于瓦穴子—乔端与朱夏两断裂之间,呈近东西向展布,主要由火神庙组、大庙组、刘山岩组等组成。铜钴镍硫化物矿赋存在火神庙组地层中,岩性主要由巨厚层状的海底基性火山岩构成。区域上已多处发现金矿、铅锌矿、铁矿、银矿等,而铜钴镍组合的矿床还没有发现过,所以在找矿方面具有一定的地质意义。Erlangping Block is located in the south margin of Northern Qinling geotectonic belt,northwestern of Henan province.The block is between the waxuezi-qiaoduan fault and zhuxia fault,extends nearly east-west,and mainly contains Huoshenmiao Group,Damiao Group and Liushanyan Group.Copper-cobalt-nickel sulfides are hosted in Huoshenmiao Group,which mainly consist of huge bedding-thickness marine basic volcanic rocks.In the region many gold deposits,lead-zinc deposits,iron deposits and silver deposits have been found,but copper-cobalt-nickel paragentic deposits had never been found before.So the discovery of copper-cobalt-nickel sulfides is of great significance for prospecting.
