Mapping the distribution of melt during anatexis at the source area of crustal granites by synchrotron micro-XRF

Ferri, Fabio; Acosta Vigil, Antonio; Perez, Carlos Alberto; Hayek, Nicolás

Description

The garnet-biotite-sillimanite enclaves from El Hoyazo are quenched anatectic metapelites found within peraluminous dacites (Betic Cordillera, SE Spain), representing a residual lower crust in the area after 40-60 % of melt extraction. Anatexis occurred concomitantly with deformation in a regional metamorphic setting during the Upper Miocene at the base of the continental crust. Previous studies have provided detailed information on the pressure-temperature evolution, sequence of melting...[Show more]
