摘要
本文介绍如何利用地球化学异常所反映的矿体剥蚀程度来评价异常深部的含矿性问题。根据热液矿床原生晕分布和元素在岩石中扩散其含量呈指数衰减的原理,本文提出了三维地球化学延拓方法并应用于金异常的评价。该方法表明了原生晕的深度变化特征,具有一定的实用意义。
This paper introduces the deep potential is evaluated by distingushing the erosiveness of surface orebo- dies indicated by geochemical anomalies. According to the principle of the primary halo distribution in hydrothermal deposits and that the element content decaies as index when it diffuses in rocks, three-dimensional continuation is presented and applied to the evaluation of gold anomaly. This method indicate the charactris- tics of primary halos as the deepth changes ,and has some practical significance.
