Paleozoic conodonts of eastern Serbia, Yugoslavia (VIII. Allochthonous Silurian, Devonian and Lower Carboniferous Limestones in the Paleozoic Flysch of Eastern Serbia)

Paleozojski konodonti istočne Srbije, Jugoslavija (VIII. Alohtoni silurski, devonski i donjokarbonski krečnjaci u paleozojskom flišu istočne Srbije)

Abstract

Conodonts from allochthonous limestones in Lower Carboniferous flysch of eastern Serbia are considered in this paper. More than a hundred species. ail of stratigraphic importance, form 27 standard conodont zones of the Upper Silurian, Lower, Middle and Upper Devonian, and Lower Carboniferous, were found in eleven localities. Primary sedimentation area of the limestones varied from deep undathem trough slope to shallow shelf. Limestones were mainly deposited on a platform edge, where carbonate sand and terrigene component accumulated and wherefrom indurated limestone was transported by gravity flows (debris flow and slumps) into a genetically different environment - noncarbonate silt-clay mud, or into relatively deep-water sediments. Several shelf slopes have been reconstructed, in flysch basin of eastern Serbia, two of which are notable: eastern slope, from Tupižnica, to Tresibaba, Miranovac and Pajež, to Donja Nevlja and farther eastward; and western slope, from Baba near Paraćin, to Leskovik, Miljkovac, Niška Banja, SW Ruj Mt. slopes, to Duboki Dol at Muren, western Bulgaria.
