Abstract
Mica samples from granitic pegmatites of Mokrusha and Ministerskaya mines, Murzinka pluton, Central Urals are polylithionite, sokolovaite, trilithionite, Li-bearing muscovite, and annite–phlogopite series. Chromium and magnesium, uncommon elements for light mica are detected in samples from both mines, indicates host-rock contamination of pegmatites. The low values K/Rb ratio and Ta/Nb ratio define a very high degree of pegmatite differentiation of both mines.
