High-Ti muscovite as a prograde relict in high pressure granulites with metamorphic Devonian zircon ages (Běstvina granulite body, Bohemian Massif): Consequences for the relamination model of subducted crust

Original language description

High-pressure kyanite-K-feldspar granulites in the Běstvina granulite body, which belongs to the Variscan orogenic root in the Bohemian Massif, preserve muscovite, rutile and kyanite inclusions in garnet. High-Ti muscovite included in garnet is associated with quartz and is in crystallographic continuity with biotite, interpreted in terms of exsolution from an original less-dioctahedral higher-Ti muscovite. The assemblage garnet-kyanite-antiperthite-perthite-quartz-rutile and the mineral compositions indicate a peak of metamorphism at about 900 C and 17-21 kbar. The matrix assemblage garnet-kyanite-plagioclase-K-feldspar-quartz-rutile-ilmenite and garnet rim compositions at contact with feldspars and quartz indicate the end of overall equilibration inthe presence of melt at 12-14 kbar and 820-840 C. Embayments of biotite and plagioclase locally replacing garnet, and connected with modification of garnet composition, may indicate sites of last isolated melt or diffusion of H2O from tha
