黑山县白厂门地区金矿物、化探特征及找矿方向探讨

摘要

Analysis of geophysical, geochemical and ore body features of gold deposits in Baichangmen area, shows that Baichangmen area gold ore bodies occurrence horizon are not only limited in Proterozoic Changcheng System Dahongyu Formation sandstone and Gaoyuzhuang Formation dolomite ductile shear contact zone, but also occurrence in nearly EW alteration quartz diorite mylonite zone of Indosinian biotite monzonitic granite rocks. Gold ore bodies and gold geochiemical anomaly zone are completely consistent, and gold abnormal belt where ore bodies occured with higher gold element anomaly value, which is not consistent with electrical method IP weak anomaly. When obtain the sites are not consistent with geophysical and geochemical anomaly, don't give up. Using surface trenching and deep drilling, it is expected to ifnd thinner thickness, higher grade gold ore bodies.%对白厂门地区金矿物化探特征和矿体特征的分析显示，白厂门地区金矿体赋存层位不仅局限于元古宙长城系大红峪组砂岩与高于庄组白云岩韧性剪切接触带上，而且赋存在印支期黑云母二长花岗岩中近东西向蚀变石英闪长岩质糜棱岩带中。金矿体与化探金异常带完全吻合，且矿体所在金异常带具有金元素异常值较高，但与物探电法激电中弱异常不吻合。得出对物、化探异常不吻合部位，也不要放弃，采用地表槽探和深部钻探工作也可望发现厚度较薄，品位较高的金矿体。
