(A) Paleogeographic reconstitution of the European Variscan Belt at the end of the Variscan orogeny (ca. 290 Ma) modified from Franke et al. (2017). (B) Geological map of the Aiguilles-Rouges and the Mont-Blanc Massifs with location of the two metapelites samples analysed and the LA-ICP-MS U-Th-Pb monazite ages obtained. Various P–T paths proposed for the Aiguilles-Rouges massif: (C) Anticlockwise P–T paths of metapelites in the Prarion and Lac Cornu areas after Dobmeier (1996, 1998). (D) Clockwise P–T paths of metapelites from the Val Bérard and Lac Emosson areas after Schulz and von Raumer (1993, 2011), Joye (1989) and Genier et al. (2008). Black arrows represent sections of P–T paths constrained by thermobarometric results and grey arrows are interpreted sections.
