摘要
In this research,software "GeoExpl"is used to process and analyze the data coming from the scale 1:50 000 stream sediment of geochemical of Jiangxi Yuhuashan.With the method of multivariate geo-statistic analysis,R-cluster analysis and initial factor matrix can be figured out from geochemical data.And the results of analysis can be used to produce single-element and integrated anomaly map to fix the elements of abnormal distribution,symbiotic relationship and genetic mechanism.In order to instruct the prediction of metallogenic,with the tool of GIS,and taken the different elements of geological background,the structure characteristics,the surface mineralization and rock mass characteristics into consideration,this research is conducted to make a tomprehensive assessment of the anomaly information of Jiangxi Yuhuashan.
