摘要
在1∶5万水系沉积物测量成果的基础上,对宁夏卫宁北山地区的地球化学参数进行计算和分析,并对元素分布特征、综合异常特征、相关性及异常元素组合特征进行研究,结果发现:区内Au、Ag、Cu的异常规模较大,与断裂构造套合性好,相对离散程度大,具有较大的成矿潜力。将优选出的综合异常进行评分排序,划分出金场子—对槽沟Au、Ag、Cu、Pb、Co找矿远景区、土窑Au、Ag、Cu、Co找矿远景区、大铜沟—照壁山Cu、Co、Ag找矿远景区及稍牛口子Au、Ag找矿远景区。
The study of the geochemical characteristics of Beishan area in Weining of Ningxia was based on the 1 ： 50 0130 stream sedi- ment survey. This paper highlighted elemental distribution characteristics, multi-elementary anomaly characteristics, element correla- tion 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 delin- eated. 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.
