摘　　要：豫西柳林地区地表存在大面积矿化和明显的区域化探金异常。为确定深部金资源远景,在蚀变矿化带上进行了放射性γ测量和电测深物探研究。测量分析显示,金矿化带具有低电阻率、高极化率、高放射性γ组合异常特征,这一组合异常特征为该区良好的金矿找矿标志。通过地表放射性γ测量及采样分析,圈出地表金矿化异常带,再利用高密度测量推断其深部矿化,共圈定了5条矿化体,估算金资源量6458kg,预测其深部具有良好的找矿前景。Big-scale mineralization and obvious regional gold geochemical anomalies have been recognized on the surface in Liulin area,west of Henan province.In order to evaluate the prospect resources of gold in this area, radiometric survey and electrical sounding have been conducted on the mineralization alteration zone.The analysis of survey shows that the gold mineralization zone is featured by an assemblage anomaly which consists of low-resistivity,high-intensive polarization and radioactivity γ.This assemblage anomaly has become the effective prospecting criterion for gold deposits.After γ radiometric survey and sampling analyses,anomalies of gold mineralization on the surface have been delineated.Furthermore,high-density survey has been completed to infer the mineralization in the deep and five mineralization bodies,which estimated resources of gold is about 6 458 kg,have been blocked-out.The deep part in this area prospects well.
