Resumen de Estudio experimental de las relaciones de fases y composición de los fundidos en sistemas anfibolíticos
Susana López Aparicio, Antonio Castro Dorado
MORB-derived amphibolites have been studied esperimentaUy in order to constrain the phase relationships and P-T conditions for beginning of melting. Experiments have been carried out in the range from 4-14 kbar and at temperatures of 850, 900 and 950 °C. The results indicate that the solidus is conditioned by the residual assemblage and this is turn by pressure. Melt compositions are coincident with tonalites for all P-T conditions.
