| dc.description.abstract | The Porcia-Salave contact aureole surround the igneous complex consisting of gabbros and granodiorites emplaced in a chlorite-zone metasedimentary rocks. Andalucite-cordierite-biotite assemblages are the most common at intermediate grade. Adjacent to the intrusive contact assemblages involving combinations of cordierite, andalusite, sillimanite and K felspar; spinel and corundum appears in quartz-absent rocks. The pressure contact metamorphism estimated on minerals equilibria is 2.6-3 kbar. Application of garnet-biotite and spinel-cordierite exchange thermometry gave T > 800 °C which are consistent with equibria involving Spl+Qtz=Crd. | en_US |
