Abstract | As a result of the geological exploration works and surveying on Pamir, there are exposed 11 pegmatite fields, which are potentially prospective in relation to the occurrence of the economic reserves of Ta, Nb, Be, Cs, Li, Sn. The most huge pegmatite fields are Shughan, South-Alichur and Namangut. Other pegmatite fields are much more smaller. Several types of rare-metal pegmatites are notable in the region. These types of pegmatites are: microdine with columbite and sorting beryl; albite with beryl and columbite-tartalite; albite-spodumene with beryl, columbite-tantalite and cassitenite. At the same time, the irregular researchings of pegmatites of various fields specify the disparities of their prognostic prospects. However, the wide of Pamir rare-metal pegmatite fields makes it possible, that on the assumption of their detail researching, there could be identified the industrial complex deposits of rare metals Li, Be, Cs, Ta, Nb, Sn. |
