Telescoping of three distinct magmatic suites in an orogenic setting: Generation of Hercynian igneous rocks of the Albera Massif (Eastern Pyrenees)

Although the magmatic rocks were emplaced contemporaneously (at about 280 My based on Rb-Sr whole-rock data), they reflect the occurrence of three genetically distinct igneous suites: one granodioritic, one leucogranitic and one mafic. The metamorphic and igneous evolution documented in the Albera Massif bears strong similarities with those described in the neighbouring Hercynian domains from the Pyrenees. The Hercynian regional HT-LP metamorphism and magmatism in the Pyrenees are two processes linked to the same deep-seated thermal anomaly that was generated in a transpressive context.
