From the top to the base of the sequence, the Triassic is characterized by lagoonal environments (Keuper), marine-to-lagoonal environments (Muschelkalk) and fluvial (lower Buntsandstein) to fluvio-deltaic environments in the upper part of the Buntsandstein (Grès à Voltzia).

We describe a new facies consisting of 'flood couplets' that include a lower, fine-grained fluvial component and an upper, coarser, unit that reflects subaerial reworking at the land surface between flood events.
