Micas from granitic pegmatites of the Mokrusha and Ministerskaya mines within the Murzinka Pluton in the Central Urals are polylithionite, sokolovaite, trilithionite, Li-bearing muscovite, and annite–phlogopite in solid solution. Chromium and magnesium, which are uncommon elements for light mica that were detected in micas from both mines indicate pegmatite contamination by the material of the host rocks. The low K/Rb and Ta/Nb ratios testify to a very high degree of pegmatite differentiation of both mines. [ABSTRACT FROM AUTHOR] |
