摘　　要：C·M·处理系统,即综合多变量处理系统,为一种新建立的区域化探异常成图及评价方法。该系统是将区域化探数据预处理后,将多个指示元素异常数据合成一种多信息数据组,经趋势面分析,由计算机输出综合多变量异常图。通过判别、聚类分析等,获得与地质—地球化学特征一致性较好的综合异常类。结合地质、物探、重砂等多方面的综合因素,进行多变量统计得分计算评价,筛选出最优异常,确定找矿靶区。C. M. processing system, namely, synthetic multi-variables processing system is a newly-found mapping and evaluatiny method used in regional geochemical exploration anomales. After the data of regional geochemical exploration have been preprocessed. Many data of anomalies of indicator elements are combined into a group of data with multi-messages. By trend surface analysis, synthetic multi-variables anomaly maps are output by computer. Through diffentiation cluster analysis, good synthetic anomaly category which are accord with geology and geochemical characteristics be obtained. In combination with geology geophysical exploration and heavy minerals, the authors have taken multi-variables into statistical calculation and evaluation, and found the best anomalies and ore propecting region.
