a Static overgrowth of biotite crystals in the thermal aureole of the VBQD on pre-existing biotite in the host paragneisses, close to the contact with stock A (Fig. 2). b Pinite + quartz aggregates after cordierite in the basement paragneisses (stock B, Fig. 2). c Statically growth of corundum (Crn) and sillimanite (Sil) within the contact aureole. d Figure (c) at crossed polars. The size of the corundum crystals allow to rule out a contamination during thin sections preparation and polishing
