摘　　要：陕西略阳杨家坝深埋铜矿受到地质背景条件影响,导致该区域内的找矿工作效率偏低。为优化略阳县杨家坝区域内的找矿工作,提出基于构造叠加晕找矿法的略阳县杨家坝深埋铜矿磁测及找矿靶区定位方法。根据略阳县杨家坝深埋铜矿地层条件、构造条件、变质作用等,对略阳县杨家坝深埋铜矿完成地磁测量,利用构造叠加晕找矿法,确定有利的成矿部位与预测靶位,定位略阳县杨家坝深埋铜矿的找矿靶区。Yangjiaba copper deposit in Luoyang county is affected by geological background conditions,which leads to low prospecting efficiency in this area.In order to optimize the prospecting work in Yangjiaba area of Luoyang county,a method of magnetic survey and prospecting target location of Yangjiaba copper deposit in Luoyang county was proposed in structural superimposed halo prospecting method.According to the stratigraphic conditions,structural conditions and metamorphism of the deeply-buried copper deposit in Yangjiaba of Luoyang county,the geomagnetic survey is completed.The favorable ore-forming position and prediction target are determined by using the method of tectonic superimposed halo prospecting.We have confirmed that the prospecting target area of the deep buried copper deposit in Yangjiaba of Luoyang county is well located.
