“…The fan system in the Rhenish Massif is characterized by transport dominantly to SW, whereas similar deposits in the Harz show an opposite transport direction. This observation, as reported by, for example Kuenen & Sanders (1956), Kulick (1960), Plessmann (1961), Sadler (1983) and Schrader (1999), resulted in a general model with two elongated turbidite fans with opposite orientation. This pattern suggests the existence of a major clastic source.…”

Investigation of the Rheno-Hercynian Turbidite Basin suggests an interrelation between orogenic wedge migration and changes of the basin architecture, facies types and progradation rates of turbidite systems. The orogenic wedge was built dominantly by the Mid-German Crystalline Rise and accreted older parts of the Rheno-Hercynian Turbidite Basin. Turbidite sequences seem to have developed in stepwise prograding sub-basins. They show systematic trends of widely correlative (tens of kilometres) large-scale cycles that show an upward transition from coarse-grained clastics to highly diluted mud turbidites with highstand shedding of carbonates. These observations suggest the existence of accommodation cycles on the assumed shelf along the Mid-German Crystalline Rise. Exposure of the shelf above sea level was associated with bypass and transport of coarse-grained clastics into the basin, whereas flooding is thought to have caused storage of clastic deposits on the shelf and the simultaneous deposition of mud turbidites in the basin. Accommodation cycles, estimated to reflect an average duration of 105 10 6 a, were probably related to cyclic changes of underthrusting in the internal parts of the orogenic wedge with concomitant uplift. The lifetime and onset of new sub-basins, of the order of a few million years, may show stages of imbricate fan formation. A pattern of major change in sedimentation rates, basin geometry and subsidence style of the Rheno-Hercynian Turbidite Basin and the Sub-Variscan Molasse Basin was interpreted to reflect the different change in crustal strength. This occurred because the hinge line between previously rifted and unrifted crust was overrun during wedge progradation. Numerical mass balance that compares exhumed and intra-basinal masses of the Rheno-Hercynian Turbidite Basin, including the proportional fill of the Sub-Variscan Molasse Basin and the Saar-Nahe Basin, indicates a significant lack of sediment mass (i.e. more than one-third of the exhumed masses). In this estimate, syn-to post-depositional truncation was included. As extension in the internal parts of the orogenic wedge has only a minor role, the above deficit is probably related to subduction of sediment during the early stages of convergence.

ABSTRACT. The Rhenish Kulm Basin is a deeper-water foreland basin developing in front of the Variscan Orogen in Germany. Three major facies interfinger and might overwhelm the adjacent one in time. These are (1) internal siliciclastic flysch facies, (2) central starved basin facies, and (3) calciturbidite facies. Calciturbidites are derived from the Northwest European shallow-water carbonate platform or not preserved intrabasinal sources. Besides, a deep intrabasinal swell facies is characterized by condensed successions. Diagnostic rock types within each facies enable the recognition of systems tracts of third-order depositional sequences. The interpretation of faunal developments and bioevents support these attributions. Hence, for the first time a sequence stratigraphic subdivision of the Rhenish Kulm Basin into 13 sequences is achieved, ranging from the latest Devonian to the early Namurian. The lower nine sequences are correlated with the Dinantian sequences earlier established on the Belgium shallow-water platform. Two Brigantian sequences 10 and 11 are identified and, despite the prograding Variscan Orogen, the two lower Namurian (Pendleian, Arnsbergian) sequences 12 and 13. The results demonstrate the successful application of sequence stratigraphy in a deeper-water basin, show that sea-level changes overrule the general, more gradual tectonic development of the basin, and prove the Palaeotethyan, if not global isochroneity of Mississippian sequences.
