Summary:During the Early and Middle Devonian, the general palaeogeographic development of the central Rhenohercynian belt was controlled in the north by the Caledonian uplands of the Old Red continent and in the south by the variable configuration of the Mid-German crystalline rise. In the deposition area between, clastic shallow marine sediments accumulated = or <4000 m in thickness by a large delta complex prograding from the north. Lithological and sedimentological continuity and extreme thicknesses of the clastic wedges support the concept that the high clastic supply and sedimentation rates were balanced by rapid subsidence of the sedimentary troughs for long periods. Isopach maps and the distribution of litho- and biofacies reflect the continuous and unilateral input of siliciclastic material from a northern source. During the late Early Devonian and Middle Devonian, a retreat of the shoreline and an overall northward migration of the accumulation centres coincided with the gradual denudation of the source area in the north. The Siegen trough apparently developed as a graben-like structure at the time when nearshore and shallow marine clastic deposits dominated throughout the central Rheinisches Schiefergebirge. Since the late Emsian a shelf/basin contrast evolved and became accentuated by reef build-ups along the SW-NE-trending shelf edge in the late Eifelian and Givetian. In this area smaller depocentres formed as half-grabens. Facies samples are presented to show the rather low topographic gradient and the extensive continuity of extreme shallow marine facies of the Early Devonian shelf, in contrast to the more differentiated facies pattern of the Middle Devonian.
