摘　　要：豫西南二郎坪地块位于北秦岭构造带南缘,呈近东西向展布,主要由火神庙组、大庙组、刘山岩组等组成。本次综合地质找矿方法的选择主要以火神庙组地层为对象;该套岩性是由巨厚层状的海底基性火山岩构成的,区域上已多处发现金矿、铅锌矿、铁矿、银矿等。由于本区厚度大、地形复杂,致使深部的赋矿情况一直是未知的。本次地质物探综合找矿方法对深部硫化物矿的成功探测,将会使本区的地质找矿工作有一个新的发展。Henan southwest of Erlangping plot is located on the southern margin of the North Qinling tectonic belt,Was near east to west, Mainly composed by the Vulcan Temple Group, Temple group, Liu Shanyan group. and so on.The selection of this comprehensive geological prospecting method mainly focuses on the strata of Huoshenmiao Formation;The set of lithology is composed of thick layers of submarine-based volcanic rocks,The area has been found in many gold,lead-zinc mine, iron ore, silver and so on.Because of the large thickness and complex topography in this area,as a result,deep ore-bearing conditions have been unknown. This comprehensive geological and geophysical prospecting method has successfully explored deep sulfide deposits,it will make a new development in geological prospecting in this area.
