From the base to the top of the Mussel Mb, five subunits have been identified (Fig. 8). The first one, the Scie Besse Beds (Fig. 8a), is a 0–5 m thick green sandstone, which microfacies is characterized by a glauconite and quartz-rich bioclastic packstone (Fig. 8b). The glauconite-rich sandstone passes upwards to a tidal crinoidal limestone showing oblique stratification and flaser structures.
