Geology comments: The Serre de Bleyton section comprises mainly turbiditic sediments (Arnaud 2005), including bioclastic grainstones rich in meso-scale fossils. The assemblages include both autochthonous and reworked components deposited in basin-floor fans (Adatte et al. 2005; Arnaud 2005). The latter deriving from the Provence Platform and hemipelagic areas to the north-west of the Vocontian Trough.
