水系沉积物地球化学测量在内蒙古凉城地区找矿应用

凉城地区1∶5万水系沉积物地球化学测量中,发现并圈定了43个以Au、Ag、Pb、Cu、Zn等为特征组合元素的综合异常,优选5处找矿远景区,经过异常查证和地质评价,优选找矿靶区,发现多处银、金、铅多金属矿（化）点及有进一步工作价值的矿产地,其中有3处被列为内蒙古地质勘查基金项目,获得了较好的找矿效果。

Application of Stream Sediment Geochemical Survey in Liangcheng Area of Inner Mongolia

On the basis of the result of 1∶50000 stream sediment（soil）geochemical survey,43 comprehensive geochemical anomalies of combined elements which were characterized by Au,Ag,Pb,Cu,Zn were discov- ered and delineated,5 blocks of preferred prospecting target area were delineated,and multiple Ag,Au,Pb polymetallic mineralization points and mineral land which worth further working value were discovered.A- mong them,3 blocks were listed in Inner Mongolia Geological Exploration Fund Project and good results have been achieved.
