Article
Central-west Turkey is a transition zone both tectonically and climatically between the quite different central and western regions of Anatolia. Central Anatolia represents the seismically quiet part of the otherwise highly active Turkey. On the other hand, this region has some of the lowest precipitation and highest evaporation ratios of Turkey. C...

Sedimentary basins in Anatolia preserve a rich record of Neogene terrestrial environments at the crossroads between Asia and Europe. Deciphering the geological evolution of these basins is essential for understanding how this fine record came to be preserved. In a reciprocal fashion, the fossil record allows for correlating between basins and for r...

Paraceratherium is an extinct genus of gigantic hornless rhinoceroses grouped in the family Hyracodontidae. The representatives of this family dispersed in large areas from eastern Asia to the Balkans during Eocene and Oligocene times. The genus Paraceratherium includes the largest species of this family; adult males are estimated to have been tall...
Article
The locality of Bıçakçı (Çameli basin, Anatolia) has yielded a diverse fauna of micromammals. The arvicolines are the most diverse and abundant group. Their stage in evolution shows that the fauna is late Villanyian in age and can be placed in the lower part of the zone P of the Anatolian Neogene biozonation. Thus, it is on the brink of the importa...

The Late Cenozoic evolution of the eastern Aegean is dominated by widespread continental extension. The most prominent structures are E-W- and NE-SW-trending grabens and intervening horsts, while NW-SE- and N-S-trending faults form the other less important structures. This paper documents the results of recent geological mapping and structural and...
Article
There are several suggestions on the age of the North Anatolian Fault (NAF) from the Middle Miocene to latest Pliocene. Late/ latest Pliocene periods were inferred by the some authors of this paper in their previous studies. We present new geological and geomorphological evidence for the age and total offset of the NAF from the Gerede-Ilgaz section...
