Abstract: The Alagewula area in Inner Mongolia is located in the Yagan tectonic belt on the northern margin of the Alashan block. It belongs to the Heiyingshan-Xiaohulishan Fe-Au-Cu-Mo-Cr metallogenic subzone in the eastern section of the Jueluotage-Heiyingshan metallogenic belt, and has a good prospecting prospect. By carrying out 1∶10000 soil geochemical survey, the distribution and enrichment rules of 13 elements such as Mo, W, Sn, Bi and Cu in the study area are basically identified, and the symbiotic relationship between elements is determined. According to the metallogenic geological conditions and the distribution and combination characteristics of each element in the study area, 12 geochemical anomalies are preliminarily delineated, which provided geochemical basis for geological prospecting in this area. Among them, AP11 is listed as a key prospecting target area. Four molybdenum polymetallic ore bodies have been discovered and delineated by the trench project, reflecting the good prospecting potential in the study area.
