The Miocene molasse

The molasse is a rock: a sandstone limestone biodetitic (which contains grains of sand and also a lot of various fossil debris). This yellowish sedimentary rock settled in the sea, around the Luberon which formed then an island or a shoal. It keeps track of the deposition conditions in agitated environment, in the form of channels and oblique stratifications. Resistant to erosion, it forms vast plateaus like that of Claparèdes!
