Limnische und fluviatile Sedimentation im südwestdeutschen Buntsandstein

The subsidence of the North German Basin, as it is known from the Zechstein period, retards during the Bunter. The basin is filled by clastic sediments. The filling up of the south German branch of the basin caused that the pelitic parts of the so termed asymmetric Sohlbank cycles were shifted towards the north during Lower and Middle Bunter. At the South German branch of the basin coarse grained deposits predominate. Under semiarid climate conditions the prevalent medium of transport was fluviatile. The erosional unconformity at the base of a new formation is described. Sediment units of minor thickness are yielded by climatic events, the cyclic process of sedimentation is fixed by dictyogenic movements (Bubnoff, like epirogenic). The described coarse grained layer of Palatinate, recognizable everywhere in the basin and caused by a dictyogenic event, initiates the transgression of the marine Upper Bunter (Röt).
