Abstract：Rare metal is important strategic mineral resource in China, and it has a wide application space in the fields of national economic construction, national defense science and technology. In recent years, three large-scale Rb-Nb-Ta rare metal mineralization belts have been newly discovered in Beishan Weiboshan rare metal mineralization belt zone in Beishan area of Inner Mongolia through geological survey, high-precision ground magnetic survey and soil geochemical survey methods. On the basis of preliminary investigation on geological characteristics and genesis of Weiboshan tantalum niobium rubidium mineralization belt, the researchers in this paper identified that the mineralization belts were in the albite and muscovite granite pegmatite vein group, with a length of 800~3 200 m, a width of 5~30 m and NWW strike. The grade of Ta2O5 is 0.003 6%~0.021 0%, and the grade of Nb2O5 is 0.009 4%~0.011 0%. Besides, the Rb2O grade is 0.046%~0.210%, indicating a medium-large metallogenic prospect. Weiboshan rare metal mineralization belt is the first discovered rare metal mineralization belt of granite pegmatite type in Beishan area of Inner Mongolia, and the prospecting work shows that Beishan mineralization belt has good rare metal resource potential, which has guiding significance for regional prospecting. And the systematic exploration and further research should be strengthened.
