Short summary
High-grade gneisses record two partial melting events: early Ordovician and early Variscan. Primary sedimentary layering is well preserved locally at the top of the sequence. First stage of the exhumation process occurred in ∼ 10 Ma. Strain was progressively localized along the boundaries of the migmatitic qz-fsp gneisses. Deformation reduced substantially the thickness of the gneissic rock sequence. "Internal" extrusion of the migmatites is documented.
