Neritic Sedimentation of the Lower and Middle Devonian in the Rheinische Schiefergebirge East of theedonian uplands of the Old Fed Continent and in the south by the variable configuration of the Mid?German Crystalline Pise. In the deposition area between, clastic shallow marine sediments accumulated up to 4000 m in thickness by a large delta complex prograding from the north. Relative lithological

“Pelagic” Carbonates in the Variscan Belt — Their Sedimentary and Tectonic Environmentsofacies studies fail to provide unequivocal evidence, the interpretation has to rely mainly on the faunas and on the character of the adjacent facies units. The local abundance of benthonic organisms (including algae) indicates that some pelagic limestones were deposited at shallow depths. Transitio

Devonian and Carboniferous Limestone-Turbidites of the Rheinisches Schiefergebirge and Their Tectoniion of allochthonous, shallow water, carbonate debris by turbidity currents, which aids in the interpretation of the history of the source regions and of the topography within the basin. The key is always to determine the flow patterns of the turbidity currents. This is rarely possible by reference

Depositional Models for the Carboniferous Flysch of the Eastern Rheinisches Schiefergebirgerapidly evolving, tectonically active troughs during the terminal phase of the development of the orogenic basin. They are derived from and then incorporated into newly influential source terrains. They were deformed at shallow or superficial crustal levels and are primary record of the orogeny.

Flysch, Olistostromes and Nappes in the Harz Mountains Nappe. In the course of the orogeny this nappe has been tectonically subdivided into several units. Whereas the majority of these units suffered relatively strong deformation, the southeastern unit (South Harz/Selke-Unit) was less deformed due to its gravitational emplacement in a relatively late p

The Mineral Composition of Rhenohercynian Flysch Sediments and Its Tectonic Significance migration of the Devonian through Upper Carboniferous flysch trough. In the Upper Namurian, the flysch grades into coal-bearing molasse. We have analyzed, by infrared-spectroscopy, the composition of the flysch- and the basal molasse rocks, and tried to fit these data into a general tectonic concep

The Sedimentary Development of the Western Rheinisches Schiefergebirge and the Ardennes (Germany/Bel is a distinct interruption of sedimentation between the Caradocian and the Gedinnian..The typical clastic facies of the Rhenish shelf with red sediments from the Old-Red-Continent was succeeded in the Middle Devonian and lower Upper Devonian by carbonates of a wide shelf lagoon. The reefbuilders di

The Chemical Composition of Sedimentary Deposits in the Rhenohercynian Belt of Central Europeajor and for 15 minor elements. Excepting the abundance of carbonate rocks and metavolcanic materials (spilites, keratophyres, quartz keratophyres) the average composition of the units is remarkably homogeneous throughout the Devonian and Carboniferous. Only the Lower Carboniferous of the SE region

Chemical Composition and Genetic Relations of Meta-Volcanic Rocks from the Rhenohercynian Belt of Nosent. The climax of volcanism occurred during the Middle Devonian, but activity continued until the Lower Carboniferous (mainly in the Lahn-Dill area)..65 spilites (including picritic and high potassium species) and 16 quartz keratophyres from the Rhenohercynian Belt have been analyzed for the major

Ey their clay mineral/(quartz + feldspar)− ratios and their carbonate contents pelitic rocks were classified into three main types: common shales (215 samples),
