Geochemical Characteristics and Ore−prospecting of Dashagou Area in East Kunlun, Xinjiang: Based on Stream Sediment Survey

Based on the 1∶50000 stream sediment survey, the distribution characteristics of ore-forming elements in Dashagou area, East Kunlun, and plentiful regional geochemical survey data was obtained. The author analyzed the characteristic of element distribution, geochemical features of stream sediment as well as the relationships between of elements, and found that the enrichment and depletion of elements relate to the formation, struture and magmatic rock, Cu, Zn, Au, Ag, Sb, Hg are more likely to be rich in integrated ore, which can be used as the main ore–forming element and indicator element in the area. A total of 37 composite anomalies and 6 potential ore–prospecting areas and 5 target area were delineated in this work, the results points out the direction for the prospecting work in the next stage.
