经验分析法是异常筛选初期常用的一种方法;综合异常评序是指评价各异常的成矿性大小,以地球化学信息为主导,以区域成矿地质背景为基础,进行评价排序。排序靠前的异常,是异常筛选考虑的重要因素。根据《湖北省马鞍山幅区域矿产调查》水系沉积物综合异常举例来说明提取地球化学异常评序参数及筛选异常,进一步指导找矿。
Empirical analysis is a commonly used method in the early stage of anomaly screening. Comprehensive anomaly sequencing refers to the evaluation of each anomaly mineralization size, which is dominated by geochemical information and is based on the regional metallogenetic geological background. The top ranked anomalies are an important factor to consider for anomalous screening. According to the comprehensive survey of sediments in the river basin in Ma’anshan, Hubei Province, we will illustrate the extraction of geochemical anomaly parameters and screening anomalies to further guide prospecting.
