摘　　要：化探的数据处理和评价(尤其是多种方法数据处理及组合异常圈定等)目前尚无明确的技术规范,实际应用中多采用2种处理方法:①所选元素为成矿的指示元素,将分析的元素全部叠加来圈定全元素组合异常;②强调指示元素的相关性,按元素相关性圈定相关元素组合异常。文章以吉林延吉纺织厂金矿化探勘查为例,对比2种方法产生的不同异常特征,认为重视元素间的相关分析、运用相关元素组合异常更加符合地球化学找矿原理,所圈定的组合异常找矿意义更明显。At present there is no clear and definite specification for procession amd assessment of geo- chemical data, especially for multi-way procession and delineation of combined anomly and in fact 2 meth ods are generally applied to the procession and delineation. In the first method some elements are choosed as indicators and chemical analsis of each elements are overprinted then the combination anomly is delinea- ted; in the second method element correlation is emphasized and the combined elements anomly is delinea-ted according to the correlation. This paper presents result of application of the 2 methods to Yanji Fang zhichang gold deposit showing that combination anomly delineated by element correlation is more suitable for geochemical prospecting with more clear significance to ore prospecting.
