Anatexia inducida: Petrogénesis de los granitos hespéricos de tendencia alcalina. Parte I: Leucogranitos del área O de Zamora y Salamanca

Abstract

According to geochemical data now available it is showed that granites interpreted as results of mesocrustal anatexis are not produced in a simple manner. It seems that in their genesis have contributed fluids and associated chemical elements arising from calc-alkaline magmas. This interpretation explains P H, 0 variation during metamorphism, geochemical anomalies, and chemical convergence with the more evolutioned faciès of the calcalkaline series. Then, considered granites are originated by means of an induced anatexis.
