Özet:

 


                        The Kangal Phyllite-Slate Formation forms the basement rocks in Kangal-Çetinkaya-Alacahan-Divriği (Sivas). These late
Paleozoic phyllite-slate associations occupy a large area, possibly composed of Early Paleozoic sediments in its lower part. The lower
levels (Bakırtepe Metaquartzite Member; 0-500 m) and uppermost levels comprise the Düzce Recrystallized Limestone Member (0-25
m). The lower boundary is invisible and the upper boundary is unconformably overlain by the Kıratgediği Limestone (late Jurassic-
early Cretaceous). The studied brachiopod fauna, about 400 specimens, was collected from the 150-m-thick uppermost part of the
greenschist sequences in the Kulluk Hill area, Elkondu village, 25 km east of Kangal. Some bryozoans, corals, trilobites, and crinoids
were also retrieved. Five fossiliferous levels belonging to the lower, middle, and upper Devonian, and the lower Carboniferous stages
were assigned as follows: (1) Pragian-Emsian; (2) Eifelian-Givetian; (3) Fransian-Famennian-Etroeungtian (Strunian); the Devonian-
Carboniferus boundary; (4) lower Carboniferus: Tournaisian and Viséan stages, based on the brachiopods; and (5) upper Permian:
from Roadian to Capitanian stages, based on the foraminifera and algae in the Düzce recrystallized limestone. This level indicates a
sedimentary interruption. All of these fossils and fossiliferous beds were correlated with the type localities and related beds. The Kangal
brachiopods are similar to those of Şafaktepe, the Gümüşali Formations (middle and upper Devonian), and the Ziyarettepe Formation
(lower Carboniferous) of the eastern Taurides. The brachiopod community is closely affiliated with the Mediterranean, northwest
European Faunal Provinces, part of the Transcaucasian Region, and microfossils of the Düzce recrystallized limestone belonging to the
Tethyan Region. Brachiopod fauna and lithologic characteristics of the formation suggest that the upper (150 m) greenschist sequences
were deposited in an open shelf environment under warm sea conditions in the Late Paleozoic era.
