摘要: From new field and single zircon geochronological data, we reinterpret the structure of Canigou orthogneisses (Eastern Pyrenees) as an Early Ordovician rapakivi granite laccolith. This laccolith is surrounded by a contact metamorphic aureole predating Hercynian tectono-metamorphic events. consists migmatites at with unmelted orthogneisses, skarns in carbonate beds retrogressed Al-rich porphyroblasts over some hundred metres beyond contact. The metallogenic activity (Fe, F) observed around massif might be related to emplacement.
