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.
Abstract
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.
