  • The Baerzhe deposit is not only a REE-Zr-Nb-Ta-Be super-large polymetallic deposit, but also a large U-Th deposit. Uranium and thorium mainly exist in the form of isomorphism. The minerals of beryllium and rare earth elements are mainly yttroceber-ysite and monazite. Niobium, tantalum and zirconium are mainly hosted in niobite, pyrochlore and zircon. Besides, in this paper, the ore-controlling factors of Baerzhe super-large deposit are analyzed from three aspects of structure, lithology and alteration. The results show that uranium-thorium mineralization is closely related to REE and rare elements mineralization in the Baerzhe deposit, and all of them occur in strongly altered riebeckite granite. Alteration is mainly albitization and silicification. The deposit is controlled by tectonics and alkaline granite body, and it is a product of structure and alkaline granitic magma evolution.
