区域地球化学异常信息提取方法研讨

在一些以成矿区带或省区为单位的区域性地球化学异常信息提取工作中,所圈定的异常经常会出现"有矿没异常或有异常没矿"的信息错位现象,给地球化学评价工作造成一定的困难。本文借助实际资料,分析了造成这种现象的主要原因,并通过对几种解决这些问题的方法技术介绍对比,提出滑动平均标准化数值法,详细介绍了滑动平均标准化数值法的方法基础、优点、具体做法以及应用效果。

Study on the method of geochemical anomalies analysis

In some course of studying the regional geochemica1 anomalies within the area of metallogenetic zones or a province, incorrect messages are often being found that there are some anomalies without mineral deposit or some mineral deposits without geochemica1 anomaly. This situation makes it difficult to evaluate geochemical anomalies. Using the information coming from practice, this paper analyses the causes of making this matter and introduces several means used to solve this problem by comparing, meanwhile, recommend another method named "gliding average standardization data method". And full details of theoretical base, its superiority and the using result of the method are given.
