; ;METU Dept. Geol. Eng.Goncuoglu, M. C.The arkosic sandstones with olistostromes within the "Karakaya Complex" in NW Anatolia to the south of Geyve include a thin layer of green chert with radiolaria. Based on the composition of Albaillellids, the radiolarian assemblage corresponds to the Neoalbaillella ornithoformisassemblage, and its age is assigned to the Changxingian (Late Permian). This is the first finding of synsedimentary radiolarian cherts within the Karakaya units and the indication of latest Permian rifting of the Karakaya basin within the Midian carbonate platform and its pre-Permian basement in the Sakarya Composite Terrane.124 350 - PublicationOpen AccessEarly Paleozoic evolution of the NW Gondwanaland: data from southern Turkey and surrounding regions(2000)
; ; ;METU Dept. Geol. Eng. ;Goncuoglu, M. C.; METU, Dept. of Geological Engineering, Ankara, Turkey ;Huseyin, K.; TPAO, Exploration Dept., Ankara, Turkey; The Lower Paleozoic assemblages in the E. Meditterranean comprise a Southern (Tauride-Anatolide,SE Anatolia and Central Iranian terranes) and a Northern (Carpathian-Balkan, Istanbul, Zonguldak and the Main Range terranes) Zone. A detailed stratigrapic account is given for these terranes for the Early Paleozoic and their paleogeographical settings are discussed to evaluate the Early Paleozoic geodynamic interpretation of this critical area between Gondwana-Perigondwana and Laurussia..159 869
