摘要
The study of the geochemical characteristics of Beishan area in Weining of Ningxia was based on the 1∶ 50 000 stream sediment survey.This paper highlighted elemental distribution characteristics,multi-elementary anomaly characteristics,element correlation and element anomaly assemblages.The results show that Au,Ag and Cu possess large anomaly area,a good parallelism with the fault and great relative dispersion extent,suggesting a huge metallogenic potential in the study area.Four prospective areas were delineated.Jinchangzi-Duicaogou area,Tuyao area,Datonggou-Zhaobishan area and Shaoniukouzi area are expected to be promising areas for Au-Ag-Cu-Pb-Co deposits,Au-Ag-Cu-Co deposits,Ag-Cu-Co deposits and Au-Ag deposits respectively.
