GEOCHEMICAL CHARACTERISTICS OF 1∶50 000 STREAM SEDIMENT SURVEY AND PROSPECTING PREDICTION IN MENGHAI AREA,YUNNAN PROVINCE
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∶50 000 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.
