A tectonic escape structure: Erciyes pull-apart basin, Kayseri, central Anatolia, Turkey

Kocyigit, A
Erol, O
A large sinistral intracontinental transcurrent structure, the Central Anatolian Fault Zone (CAFZ), is located between Erzincan in the northeast and offshore of Anamur county in the southwest of Turkey. Northeastern and southwestern segments of the fault zone are linked to each other by an intervening and approximately NS-trending transtensional structure, the Erciyes pull-apart basin (EPB). The Kizilirmak-Erkilet and Dokmetas segments of the CAFZ bend southwards at about 45 degrees -50 degrees near Kayseri and result in a releasing double bend, which has nucleated both the EPB and its main feature, the Erciyes stratovolcano complex (ESVC) since Middle Pliocene time. The EPB is a similar to 35-km-wide, 120-km-long, 1.2-km-deep, lazy S-shaped and actively-growing depression with the ESVC forming a high-standing central barrier between the northern and southern parts of the basin. Hence, the EPB appears as two separate basins, namely the 'Sultansazligi and Kayseri-Sarimsakli depressions'. However this is not correct, because development of the EPB and ESVC has been coeval with the volcanic activity producing the ESVC continuing into prehistoric times. Development of the EPB is continuing as indicated by faulted, uplifted and terraced Pleistocene-Early Holocene palaeolake beach deposits, and historical to recent earthquakes. Accumulative throws on the eastern and western margin-bounding faults of the EPB are 1225 m and 720 m respectively and show that basin development has been asymmetrical.

Neotectonic evolution of the northwestward arched segment of the Central Anatolian Fault Zone, Central Anatolia, Turkey
Dirik, K (2001-01-01)
Central Anatolia has undergone complex Neotectonic deformation since Late Miocene-Pliocene times. Many faults and intracontinental basins in this legion were either formed, or have been reactivated, during this period. The eastern part of central Anatolia is dominated by a NE-SW-trending, left lateral transcurrent structure named the Central Anatolian fault zone located between Sivas in the northeast and west of Mersin in the southwest. Around the central part, it is characterized by transtensional depressi...
Modeling of a historical earthquake in Erzincan, Turkey (Ms similar to 7.8, in 1939) using regional seismological information obtained from a recent event
Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül (2018-06-01)
Located within a basin structure, at the conjunction of North East Anatolian, North Anatolian and Ovacik Faults, Erzincan city center (Turkey) is one of the most hazardous regions in the world. Combination of the seismotectonic and geological settings of the region has resulted in series of significant seismic activities including the 1939 (Ms similar to 7.8) as well as the 1992 (Mw = 6.6) earthquakes. The devastative 1939 earthquake occurred in the pre-instrumental era in the region with no available local...
An Active Composite Pull-apart Basin Within the Central Part of the North Anatolian Fault System: the Merzifon-Suluova Basin, Turkey
Rojay, Fuat Bora (2012-07-01)
The North Anatolian Fault System (NAPS) that separates the Eurasian plate in the north from the Anatolian microplate in the south is an intracontinental transform plate boundary. Its course makes a northward convex arch-shaped pattern by flexure in its central part between Ladik in the east and Kargi in the west. A number of strike-slip basins of dissimilar type and age occur within the NAFS. One of the spatially large basins is the E-W-trending Merzifon-Suluoya basin (MS basin), about 53 km long and 22 km ...
Tectono-stratigraphic evolution of the continental miocene basins in Southwest Anatolia
Koç, Ayten; Kaymakcı, Nuretdin; Van Hinsbergen, Douwe J. J.; Department of Geological Engineering (2013)
The Tauride range in southern Turkey is flanked and overlain by Neogene sedimentary basins. To the south and on top of the high range, these basins are mainly marine, whereas poorly studied intra-montane basins dominated by continental deposits are exposed to the north. In this study, the stratigraphy and structure of these continental basins which includes Altınapa, Yalvaç and Ilgın Basins are studied. Their stratigraphy of these basins displays poorly expressed fining upwards sequences of fluvio-lacustrin...
Modeling permian petroleum system of Netherlands: hydrocarbon generation and migration
Mert-Gauthier, Esra; Kaymakcı, Nuretdin; Özacar, Atilla Arda; Department of Geological Engineering (2010)
Groningen Gas Field is located within the southern part of the South Permian Basin in the northeast Netherlands. Since several wells have been producing from the Carboniferous-Permian Petroleum System, the field is considered as mature for hydrocarbon exploration. More detailed work is necessary to evaluate further exploration and development opportunities. Thus, evaluation of the subsurface has been carried out as part of the petroleum system concept by using the basin modeling. In this study, seismic inte...
