Formation of elliptical garnet in a metapelitic enclave by melt‐assisted dissolution and reprecipitation

Journal of Metamorphic Geology, 2005
AbstractMetapelitic residual enclaves in the Neogene Volcanic Province of SE Spain are residues left after melt extraction. Glass (quenched melt) of granitic composition occurs as inclusions in most minerals and as intergranular pockets. The most common enclave types show one stage of garnet growth that is interpreted to have occurred at the same time ...

Metapelitic Garnet-Muscovite-Al2SiO5-Quartz (GMAQ) Geothermobarometry

Journal of Earth Science, 2018
The garnet-muscovite geothermometer and garnet-muscovite-Al2SiO5-quartz (GMAQ) geobarometer have been empirically calibrated under P-T conditions of 1–12 kbar and 460–760 oC using natural metapelitic rocks. The chemical compositions of the calibrant muscovite are in the ranges of Fe=0.03–0.21 atoms, Mg=0.02–0.32 atoms and AlVI=1.62–1.96 atoms ...
