Rodríguez Vieítez, N.Suárez Hernando, Oier2015-02-032015-02-032000http://hdl.handle.net/10272/9793The 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.spaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Contact aureoleThermometryQuartz-absent rocksSpinelCorundunjournal articleopen access
