The east Anatolian plateau and the Lesser Caucasus are characterised and shaped by three major structures: (1) NW-and NE-trending dextral to sinistral active strike-slip faults, (2) N-S to NNW-trending fissures and /or Plio-Quaternary volcanoes, and (3) a 5-km thick, undeformed Plio-Quaternary continental volcanosedimentary sequence accumulated in Various strike-slip basins. In contrast to the situation in the east Anatolian plateau and the Lesser Caucasus, the Transcaucasus and the Great Caucasus are characterised by WNW-trending active thrust to reverse faults, folds, and 6-km thick, undeformed (except for the fault-bounded basin margins) continuous Oligocene-Quaternary molassic sequence accumulated in actively developing ramp basins. Hence, the neotectonic regime in the Great Caucasus and the Transcaucasus is compressional-contractional, and Oligocene-Quaternary in age; whereas it is compressional-extensional, and Plio-Quaternary in age in the east Anatolian plateau and the Lesser Caucasus.

Tectonic history of basins sited along the western section of the North Anatolian Fault System, Turkey
SARP, Gülcan; Gurboga, Sule; Toprak, Vedat; Duzgun, Sebnem (2014-01-01)
Geological and geomorphological features of basins along the western half of the North Anatolian Fault System (NAFS) are used to constrain the formation of these basins by localization of deformation and the total displacement, and to determine the timing of basin development. In this study, tectonic influence direction of the NAFS on tectonic and hydrologic basins Bolu, Yenicaga, Dortdivan, Cerkes, Ilgaz and Tosya has been investigated to deduce information about the formation stages and interaction betwee...

New geochemical, Sr/Nd isotope and zircon U-Pb LA-ICP-MS data from the Derik Volcanics in the Southeast Anatolian Autochthone Belt of Turkey are consistent with an Andean-type Cadomian arc that developed along the northern edge of the Arabian Plate during the Late Neoproterozoic. The Derik Volcanics represent a volcanic complex including andesites, rhyolites and basalts, with volcanoclastic and fluvial sediments. They are unconformably overlain by playa sediments with Early Cambrian ichno-fossils, followed ...
Palaeoenvironmental and chronological constraints on the Tuglu Formation (Cankiri Basin, Central Anatolia, Turkey)

The Cankiri Basin, located in the northern part of the Central Anatolian Plateau, is a large Tertiary basin where thick Miocene to Quaternary continental sediments overlay the Cretaceous-Tertiary units. This investigation focuses on the Tuglu Formation, an Upper Miocene succession mainly composed of dark grey silty and organic rich clays. The type section of Tuglu has been sampled for an array of multidisciplinary analyses. The palaeontological proxies included ostracod, foraminifer, nannoplankton, pollen, ...
Neotectonics of the southeast Marmara region, NW Anatolia, Turkey
Gürer, Ömer Feyzi; Kaymakcı, Nuretdin; Çakır, Şerafeddin; Kaymakcı, Nuretdin (Elsevier BV, 2003-7)
The North Anatolian Fault Zone (NAFZ) bifurcates into three branches in the Marmara Region, which is a transition zone between the strike-slip tectonics manifested by the NAFZ and the N-S directed extensional regime of western Anatolia. The southern Marmara region is characterized by the middle and the southern branches while the northern branch controls the north Marmara region. The south Marmara region is characterized by approximately E-W trending rhomb-like horst and graben complexes bounded by strike s...
