| 英文摘要 | In recent years, the Himalayan leucogranite belt is considered as a favorable area for rare-metal mineralization, and many rare metal minerals have been found in this area. The Cuonadong deposit is the first newly discovered giant W-Sn-Be deposit in this belt. The beryllium mineralization includes pegmatite-type and skarn-type, but the occurrence state of beryllium element in this deposit is still unclear. Pegmatite-type mineralization is represented by beryl with better crystals, while skarn-type Be mineralization has various manifestations. The Be element not only occurs in beryllium-containing minerals such as beryl, phenacite and bertrandite, but also can be widely distributed in some skarn minerals. Among them, the contents of Be in vesuvianite and scapolite vary within 43 x 10(-6) similar to 887 X10(-6) and 1333 x 10(-6) similar to 4643 x 10(-6), respectively. The genesis of skarn mineralization is related to the emplacement of leucogranites. The high degree of magma differentiation gradually enriches Be, Sn, W and volatiles in the melt, and saturates the beryl in the pegmatite; then the Be element is complexed by F within the fluid released from the magma and enters the carbonate. The fluid interacts with the carbonate, and the precipitation of fluorite causes the instability of the Be-F complex, leading to the precipitation of the Be element. The study on the occurrence state and mineralization mechanism of Be element in Cuonadong deposit is helpful to guide the exploration of the similar type of deposits in the Himalayas. |
