Omphacite, glaucophane and phengite inclusions in rutile from the Buldym ultramafic massif (South Ural)

Mineralogy of the Buldymskiy serpentinized dunite massif (South Ural) was studied. A wide variety of minerals including: olivine, enstatite, serpentine, Cr-spineles, pyrite, rutile, tschermakite - hornblende, corundum,dolomite, plagioclase, barite and garnet was identified. The omphacite, glaucophane, phengite and titanite inclusions were determined in rutile for the first time. The equilibrium Omp + Gln + Ph + Ttn assemblage is caused by T from 500 to 600 °C and P ³ 15 kbar, that probably marks an intermediate evolution stage of alkaline-ultramafic rock association.
