Integrated bio- and chemostratigraphy of the Upper Ordovician and lower Silurian of the Central and Eastern Taurides, Türkiye

To establish the stratigraphical position and the exact age of the Silurian “hot shales” in the Taurides and SE Anatolia, a number of sections were measured and sampled in detail. Graptolite data obtained from this study suggests that Lower Silurian is almost complete in the Taurides and includes more than one black shale interval. In the Eastern Taurides the measured sections are in Tufanbeyli-Pekmezkoy and Sariz-Degirmentas; additional spot samples were taken from Sariz-Mirzaaga, Tufanbeyli- Armutalan and Saimbeyli-Gurleflen sections. In the Central Taurides, Silifke-Ovacik and Bozyazi-Tekmen sections were measured and spot samples were taken from Silifke-Somakli section. In the Western Taurides the Antalya-Kemer section was investigated and dated by conodonts from the limestone interlayers. In SE Anatolia, representing the northern margin of the Arabian Platform, Cermik-Southern Korudag section was measured and the Gerger Cat section was investigated by a number of spot samples. In most of the studies sections in the Taurides, Hirnantian glacio-marine siltstones with channel-type sandstone bands and lenses make up the substratum of the measured sections.
