Trachyandesite dome-flow, with numerous mafic enclaves, coming from Mont Redon. Good outcrops on the road to Chastreix-Sancy ski station, just below the Roc de Courlande.
Note on the mineral list: Titanite was erroneously reported following the beginning of this discussion: https://www.mindat.org/mesg-601214.html. Actually, the crystals photographed by Alex are titanite, but they couldn't have come from Roc de Courlande where titanite was never reported by dozens of micro-mineralogists who have collected here (Jean-Marc Johannet).

"Erroneously reported as titanite was never found at Roc de Courlande. The sample illustrated by Alex should come from another place in Massif du Sancy like
