青海黑刺沟金矿床原生晕深部找矿预测

Prediction of Deep Halo Prospecting of Black Ditch Gold Deposit in Qinghai

基于青海黑刺沟HS25号异常区前期勘查成果资料,以原生晕分带指数法、数理统计法及构造叠加晕找盲矿法,分析了8勘探线AP1土壤异常中金矿体原生晕分带特征及其深部找矿前景,并对其它土壤异常深部找矿前景进行了浅析。表明矿体主要元素垂向由下向上为Pb→Au→Sb→As→Ag→Mo分带序列,Mo是前晕,Sb、As、Ag为近矿晕,Pb是尾晕;该金矿体深部原生晕特点显示无金盲矿,相应有铜盲矿的依据。土壤综合异常北带的剥蚀程度相对中段大两侧小,南带由北西向东南由大到小;剥蚀程度和水平分带特点显示南带中东段土壤异常区有良好的深部找金前景。

Based on the results data of Qinghai black thorn ditch HS25 anomaly preliminary exploration, we, with primary halo zoning index method, including mathematical statistics method and the method of structural superimposed halos for blind ore, have analyzed No. 8 prospecting line in AP1 soil anomaly cicc of orebody primary halo zoning characteristics. A deep prospecting prospect and other deep soil anomaly prospecting prospect were in a serious analysis. It is shown that the main elements of the orebody are vertical Pb→Au→Sb→As→Ag→Mo zone. Mo is dronted. Sb, As, Ag is near halo. Pb is tail halo. Deep native halo characteristics will show no sign of goldblind mine under current condition of the corresponding basis of copper blind ore. The denudation degree and the horizontal zonation characteristics show that the soil anomalies in the middle and eastern section of the south zone have a good prospect of prospecting.
