摘　　要：西坞口锰及铜锡多金属矿区地形切割剧烈,传统的电法勘探难以取得找矿效果,因此,寻找有效的找矿手段是该区域找矿工作取得突破的关键。结合区内磁异常和地球化学特征,分析区内成矿有利构造,进而达到找矿的目的。区内只有花岗闪长岩具有磁性,根据高精度磁测结果显示,磁异常分布基本反映了区内花岗岩体及含矿构造的走向分布。根据地球化学Hs1号综合异常带各元素分布特征,各元素异常具有明显的定向排列特性,其定向排列性与区内主要断层F2的方向基本一致。通过高精度磁测结合地球化学元素分析结果显示,在区内寻找铜锡矿具有显著效果。The topography of Xiwukou manganese and copper-tin polymetallic mining area is severely cut,and the traditional electrical prospecting method is difficult to obtain prospecting results.Therefore,finding effective prospecting means is the key to make a breakthrough in this area.Combined with the mag⁃netic anomaly and geochemical characteristics of the area,the favorable ore-forming structures in the area are analyzed to achieve the purpose of prospecting.Only granodiorite has magnetic properties in the area.Ac⁃cording to the high-precision magnetic survey results,the distribution of magnetic anomalies basically re⁃flects the strike distribution of granite mass and ore-bearing structures in the area.According to the distribu⁃tion characteristics of elements in the comprehensive anomaly zone of geochemical Hs1,each element anom⁃aly has obvious directional arrangement characteristics,and its directional arrangement is basically consis⁃tent with the direction of the main fault F2 in the area.The results of high-precision magnetic survey com⁃bine with geochemical element analysis show that it is of remarkable effect to search for copper tin deposits in the area.
