Abstract:

Geochemical exploration is one of the quickest prospecting methods to discover prospective area and reduce the target area. Based on the 1∶50,000 soil geochemical survey, this paper studies the geochemical characteristics of 18 elements in Weibo mountain area, summarizes the distribution law of 18 elements. It is found that the anomalies of Rb, Nb, W, Mo, Bi, Au, Cu in the area are significant. Ten comprehensive ano-malies are delineated and the metallogenic potential of the main comprehensive anomalies is evaluated. It can be found that AP5(B2)comprehensive anomaly has geological-geochemical conditions for gold polymetallic deposit, AP6(B1)comprehensive anomaly has potential for large-scale Rb-Nb-Ta mineralization and AP8(B2)comprehensive anomaly has W-Mo-REE mineralization. For the anomaly verification, the gold ore (mineralization) bodies were found in AP5, and rare and rare earth elements ore (mineralization) bodies have been found in AP6 and AP8, which have great metallogenic potential. Among them, the discovery of granite pegmatite Nb-Ta-Rb and high temperature hydrothermal Mo-REE mineralization types is the first case in Beishan metallogenic belt, Inner Mongolia. Meanwhile, it also provides the basis for the change of prospecting ideas in this area.

Key words: soil geochemical survey, element distribution law, rare and rare earth elements polymetallic ore(mineralization), metallogenic potential, Weibo mountain area, Ejina Banner, Inner Mongolia
