Xenolitos peridotíticos y piroxeníticos del volcán El Palo (Campo Volcánico de Calatrava, España)

Abstract

El centro volcánico de El Palo contiene varios tipos de xenolitos ultramáficos (peridotitas y piroxenitas) que registran diversos procesos ocurridos en el manto litosférico. Estos enclaves están equilibrados a temperaturas altas (1072– 1127ºC) y presiones muy variadas (7.3–13.8 kbar), dependiendo del tipo de enclave muestreado. El conjunto de xenolitos equilibrados a mayor profundidad son peridotíticos. Consisten en dos grupos de lherzolitas y una werhlita, que, en este orden, muestran gradualmente más enriquecimiento en Fe-Ti y patrones más fraccionados de REE normalizados al condrito. Los enclaves clinopiroxeníticos representarían acumulados fraccionados de magmas basálticos alcalinos a distintos niveles del manto y equilibrados en el límite con la corteza. La websterita, con mayor contenido en Al2O3 y menor en Cr2O3, está equilibrada a mayor profundidad que las clinopiroxenitas y su origen podría estar relacionado con magmas más subalcalinos.
