Abstract

Abstract

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.
- stream sediment /
- geochemical anomaly /
