In the French sedimentary basins, widespread alluvial deposits sealing narrow Permian troughs are referred to as ‘Buntsandstein’. An Early Triassic age is generally put forward despite a lack of any Scythian biochronological elements. In Provence (Southeast Basin) some doubts remain about the age of the latest Permian deposits, and the oldest Triassic fossils (Anisian palynomorphs) appear in the upper ‘Buntsandstein’. Three types of contact occur: disconformity overlain by a quartz-Conglomérate, apparent transition, and angular unconformity, according to an increasing basal incompleteness of the ‘Buntsandstein’. Whereas the Conglomérate was deposited under arid conditions, the overlying fluvial deposits indicate a marked...
