浅析地球化学综合异常的圈定及找矿效果

Analysis of delineation and prospecting effect of geochemical synthetic anomalies

本文采用了马氏距离识别地球化学离群点的圈定方法,对地球化学的综合异常进行圈定。使用该方法进行圈定,不但界线清楚,而且边界唯一,还避免了人为进行圈定异常可能产生的诸多不良影响;具有指标单一,而且异常强度十分突出的特点,非常有利于矿体的发现。

In this paper, the method of Mahalanobis distance identification of geochemical outlier is adopted to delineate the geochemical anomalies. Use this method to determine, not only clear boundaries, but the boundary only, but also to avoid the adverse impact the anomalies may arise; with single index, and abnormal strength very prominent features, is very conducive to the discovery of ore body.
