摘要
勐海地区处于临沧-勐海(岩浆弧)Fe-Pb-Zn-Au-Ag-Sn-Sb-Ge-REE矿带,具有较好的找矿前景.在勐海地区1∶5万水系沉积物测量基础上,对区内29种元素分布特征、元素相关性、地球化学参数特征研究,圈定了5个组合异常和13个综合异常.其中,Ce-La-Y-Zr综合异常具有较好找矿前景;Au、As、Sb、Hg、W、P等元素离散程度较高,元素局部较富集,具有成矿的可能性.结合水系沉积物测量成果,圈定找矿远景区2处,为下一步找矿工作提供了地球化学依据.
Menghai area is located in Lincang-Menghai(magmatic arc)Fe-Pb-Zn-Au-Ag-Sn-Sb-Ge-REE metallogenic belt,with a good prospecting potential.Based on the regional 1∶50000 stream sediment survey,the distribution characteristics,element correlation and geochemical parameter characteristics of 29 elements are studied,and 5 composite anomalies and 13 comprehensive anomalies are delineated in the area.Among them,the Ce-La-Y-Zr comprehensive anomaly has a good prospecting potential.The elements of Au,As,Sb,Hg,W and P are highly dispersed and locally enriched,with possibility of mineralization.Combined with the stream sediment survey results,2 prospecting potential areas are delineated,which may provide geochemical basis for the next prospecting work.
