Abstract

Abstract

Related to alkaline granite, the 801 oversize rare REE deposit lies in Ba'erzhe anticline of NNE direction, Zhalute territory of Tongliao City, Inner Mongolia. Mainly composed of niobium (Nb), yttrium (Y), tantalum (Ta), the deposit also contains various rare REE such as beryllium (Be) and so on. The ore-bearing rock is mineralized alkaline granite formed during Yanshanian, and its ore body has generation relations with the 801 rare REE deposits. The author has comprehensively analyzed the alkaline granite from perspectives of petrological characteristics, ore potentiality, the variation law of ore-bearing elements, the relationship between rock chemical composition and rare elements, the enrichment patterns of mineralization elements and genesis of deposit, and concluded that 801 REE deposits belong to late magmatic differentiation metasomatic deposits of alkaline granite.
