宁夏中卫卫宁北山地区水系沉积物测量地球化学特征及找矿方向

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。%ThestudyofthegeochemicalcharacteristicsofBeishanareainWeiningofNingxiawasbasedonthe1∶50000streamsedi-mentsurvey.Thispaperhighlightedelementaldistributioncharacteristics,multi-elementaryanomalycharacteristics,elementcorrela-tionandelementanomalyassemblages.TheresultsshowthatAu,AgandCupossesslargeanomalyarea,agoodparallelismwiththe faultandgreatrelativedispersionextent,suggestingahugemetallogenicpotentialinthestudyarea.Fourprospectiveareasweredelin-eated.Jinchangzi-Duicaogouarea,Tuyaoarea,Datonggou-ZhaobishanareaandShaoniukouziareaareexpectedtobepromisingareas forAu-Ag-Cu-Pb-Codeposits,Au-Ag-Cu-Codeposits,Ag-Cu-CodepositsandAu-Agdepositsrespectively.
