摘　　要：不同矿床热液来源及元素地球化学特征的差异,导致每一种矿床都有一套自己特有的原生晕指示元素组合。研究不同元素的地球化学分带特征,对预测深部盲矿体的存在具有非常重要的作用。本文对天子坪金矿区钻孔内的原生晕分带特征做了分析,建立了该区不同元素的地球化学垂向分带模式,分析了矿区剥蚀程度,确定了AP-4综合异常为深部找矿优选异常。Due to the differences in hydrothermal sources and geochemical characteristics of different deposits,each deposit has its own set of original halo indicator elements.The study of geochemical zonation characteristics of different elements plays an important role in predicting the existence of deep blind ore bodies.This paper analyzes the characteristics of primary halo zoning in the borehole of tianziping gold mining area,establishes the geochemical vertical zoning model of different elements in the area,analyzes the degree of denudation in the mining area,and determines that AP-4 comprehensive anomaly is the optimal anomaly for deep prospecting.
