dc.description.abstractThe Manzalvos-Castromil massif (NW Iberian Hercynian Belt) is mainly composed of granitoids that define an alumino-potassic association. Magmatic microgranular enclaves and scattered amphibole-biotite intermediate rocks are present in the massif. These rocks are later intruded by some two micas granites and leucogranites that result in hybrid contact zones. Field relationships point out to a quasi-simultaneous intrusion of both basic magmas and granitoids. The hybrid nature of the calcoalkaline basic magma is deduced from its petrological, mineralogical and geochemical characteristics. They are derived from a basic magma evolving by assimilation and contamination with crustal components in the middle continental crusten_US
