摘要

地球化学异常评价的主要任务是区分矿致异常和非矿致异常以及就此提出远景预测区,但如何进行异常评价,往往缺少定量分析及数据的佐证,且对成矿地质条件的分析,就利用目前矿区勘查的传统手段,很难理清矿区的成矿地质特征,影响了矿区的找矿预测。故对矿区土壤地球化学异常元素组合、规模及异常的分带性分析,结合已知地质背景,利用数理统计的方法对地球化学异常成果进行评价,就如何圈定及利用地球化学综合异常成果进行找矿预测进行分析探讨,旨在对矿区找矿靶区进行优选及效果评述,以取得更理想的地质找矿效果。
        The main task of geochemistryanomaly assessment is to distinguish between mineral anomalies and non-mineral anomalies and propose a long-range prediction area. However,how to carry out anomaly assessment is often lack of quantitative analysis and data support,and the analysis of mineralization geological conditions is based on the traditional method of the current mineral survey,which is difficult to understand the ore-forming geological features in the mining area and affects the prospecting prediction in the mining area. Therefore,the elemental composition,scale and anomaly zonation of soil geochemistryanomalies in the mining area were analyzed. Combining known geological backgrounds,using mathematical statistics methods to evaluate the results of geochemistry anomalies,and carrying out analysis and exploration on how to delineate and use geochemistrycomprehensive anomaly results to carry out prospecting predictions,its final aim is to optimize and prospect target areas in mining areas and achieve better geological prospecting results.
