A Paleogeographic Approach to the Devonian of Turkey
In Turkey Devonian rocks are exposed in the northwestern parts of the Pontides, in the Taurides and in the Border Folds. At the end of the Paleozoic the Pontides region was folded; the Taurides and Border Folds, however, remained undisturbed by orogenic events until Cretaceous time. In the Border Folds region Devonian sedimentation took place only in the northern part (Hazro region), whereas the southern part (Derik region) was probably not a sedimentation area.
In the Taurus Belt, in the area around Tufanbeyli and Silifke, Devonian rocks are present in subtidal, intertidal, supratidal and restricted basinal facies. In the area around Antalya and Konya, the sedimentation realm of the Devonian rocks must have been divided by an uplifted continental area (named herein the Hadim-Sultandag Uplift) creating two different basins. Devonian and Carboniferous sediments of the southern basin have a restricted and/or closed basinal character (the parent basin of the Pamphylian basin sensu Dumont et al.). Devonian rocks of the northern basin are developed on the shallow shelf of an open marine environment.
The many disconformities and unconformities observed in the Paleozoic and early Mesozoic sequences should be interpreted as results of epeirogenic movements, caused by blockfaulting during the drift of the plate.
