T1 A new interpretation of the relationships between hercynian granitoid emplacement and metamorphism in the Eastern Pyrenees
A1 Enrique Gisbert, Pere
AB The Hercynian outcrops of the Cap de Creus (Eastern Pyrenees) allow to relate the intrusion of calcalkaline m agm as to low-pressure and high-temperature regional metamorphism. The coexistence o f basic and intermediate magmas with anatectic migmatites, and a well-developed field of pegmatitic bodies inside the sillimanite zone, suggest that hot mantle or deep crustal-derived magmas ascending to the upper levels of the crust were the heat source for such high-thermal gradient regional metamorphism. Shallow-level emplaced batholiths and andesitic volcanism in the Hercynian Pyrenees might have been fed by this magmas, mixed in several degrees with the anatectic melts
