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, ...
Late Campanian Maastrichtian evolution of orbitoidal foraminifera in Haymana Basin succession Ankara Central Turkey
Özcan, Ercan; Altıner, Sevinç (1997-01-01)
In Central Anatolia, a thick sedimentary succession composed of deep-water turbiditic units represented by marl-shale, sandstone, olistostromal horizons and carbonates crops out. This succession constitutes the lower part of so-called Haymana Basin spanning the Santonian (?)/Campanian-Eocene time interval. Evolution of Lepidorbitoides and Orbitoides concerning embryonic features and the initial chamber arrangement has been investigated in the Late Cretaceous part of this succession. Previously unrecognized ...
Miocene tectonic history of the Central Tauride intramontane basins, and the paleogeographic evolution of the Central Anatolian Plateau
Koç, Ayten; Kaymakcı, Nuretdin; Van Hinsbergen, Douwe J. J.; Kuiper, Klaudia F. (2017-11-01)
Marine Lower-Upper Miocene deposits uplifted to > 2 km elevation in the Tauride mountains of southern Turkey are taken as evidence for the rise of a nascent plateau. The dynamic causes of this uplift are debated, but generally thought to be a regional dynamic topographic effect of slab motions or slab break-off. Immediately adjacent to the high Tauride mountains lie the Central Tauride Intramontane Basins, which consist of Miocene and younger fluvio-lacustrine basins, at much lower elevations than the highl...
