Is there a time lag between the metamorphism and emplacement of plutons in the Axial Zone of the Pyrenees

Detailed petrographic and geochemical studies conducted on zircons from the Lys-Caillaouas pluton reveal their igneous and metamorphic affinities. The igneous zircons constrain the emplacement of the pluton to 300±2 Ma. By contrast, the metamorphic zircons yield an older age of 307±3 Ma, which probably dates the thermal peak of the HT/LP Variscan metamorphism. Therefore, a short time lag of c . 7 Ma emerges between the metamorphic climax and emplacement of the pluton in the Axial Zone (Pyrenees).
