分散流异常的二次指标远景评价

Secondary Index of Dispersion Train Anomaly for ore Potential Evaluation

本文介绍一种分散流数据处理方法,是以区域成矿地质背景分析为前提,以地质体为单元划分区段,在相应地质体中典型矿床地化异常模式建立的基础上,提取特征元素组合、头尾晕指示元紊和具特征指示意义的元素,确定实用型二次评价指标.并举例说明应用效果.

A method for dispersion train anomaly data processing is presented in this paper, on the premise of an analysis of regional geological-metallogenic background, by taking the geological body as a unit for dividing the region in sections, and on the basis of the geochemical anomaly pattern built for the typical ore-deposits in corresponding geological bodies. By using this method a combination of characteristic elements, front and rear indicator elements, and characteristic elements of indicative significance are extracted in order to determine the practical secondary evaluation index. A practical example is cited for illustration.
