Abstract:

The Wuheshalu area is located in the west margin of Tarim basin, Wuqia County, Xinjiang. More than 20 metal deposits (mineralized spots) have been found in Wuheshalu and the surrounding area, which have a good prospecting direction for copper, lead and zinc. Through 1∶50,000 geochemical survey of stream sediments in the Wuheshalu area, we have analyzed the geochemical characteristics of 15 elements such as Cu, Pb, Zn, Ag. Based on the differentiation, enrichment and superposition degree, we conclude that there is good potential for the concentration and mineralization of elements of Cu, Pb, Zn, Ag, Sb, Sn, Sr, and W,and these elements are the main ore-forming elements in the study area. According to the anomaly characteristics and metallogenic geological conditions, fifteen geochemical complex anomalies, in addition to three prospective areas are delineated, namely the Wuheshalu Cu-Sr-Pb-Ag polymetallic ore prospective area, the Xiaoerbulake-tao Cu polymetallic ore prospective area and the Aketao Cu-Sr polymetallic ore prospective area,respectively.This paper points out the direction for the prospecting work in the next stage.

Key words: stream sediment survey, geochemical characteristics, sandstone type copper mine, metallogenic prospective area, Wuheshalu area, Xinjiang
