Rare-metal pegmatites of the north-eastern part of Kola pegmatite belt: geology and geochemistry (Kola Peninsula)
The article presents data on the geochemistry of pegmatites in the Soldier-Mylk region of the north- eastern part of the Kola pegmatite belt. Spodumene and feldspar pegmatites were shown to have features typical of rare-metal pegmatites: elevated Li, Be, Ta, Nb, Cs, Rb P, B, low Sr, Ba, Zr and REE, low ratios Zr/Hf, Ba/Rb, Sr/Rb. The data obtained indicate the promise of pegmatite in relation to rare metal mineralization.
