Neotectonics of Altıntaş (Araban, Gaziantep) basin, SE Turkey

Çiçek, Aydın
Altıntaş basin is an approximately 6-9 km wide, 50 km long and E-Wtrending depression located in the northwestern margin of the Arabian Plate. The Study area is bounded by the Kırkpınar fault zone to the west, by the Güllüce Fault Zone to the north, by the Bağlıca, Akdurak, Erenbağ and Fıstıklıdağ Fault Sets to the northeast, by the Kemerli Fault set to the east and Karasu Fold Set to the south. Altıntaş Basin comprises two distinct basin fills separated by a clear angular unconformity. (1) Middle Eocene-Pliocene deformed fill and (2) Early Quaternary to recent nearly flat lying fill. Field observations reveal that Middle Eocene to Pliocene units developed inside a foreland system under the control of dominantly NNW-trending mainly contractional deformation. This phase is named as “phase-1”. In addition to this, the pre-modern Altıntaş ramp-basin formed due to separation of the Araban Block from the northwestern margin of the Arabian vi Plate at the end of Phase-1. Later, NNW-trending maximum principal stress axis was modified into NW to E-W-trends with strike-slip tectonic regime. This term has been regarded as Phase-2. During this phase, the basin configuration did not change significantly. Later, the maximum principal stress axis has become dominantly NNE-trends in relation to onset of escape of the Anatolian Collage. This phase has been regarded as Phase-3 or the neotectonic period. During this period, the Altıntaş basin restricted to a smaller area due to formation of a strikeslip basin.


Neotectonics and evolution of the yeniçağ basın, Bolu-Turkey
Arca, M Serkan; Koçyiğit, Ali; Department of Geological Engineering (2004)
Study area, the Yeniçaga Basin, is located in the western part of the North Anatolian Fault System. It is a 1-5-km-wide and 14-km-long WSWENE- trending depression bounded by a complex array of strike-slip faults. The Yeniçaga Basin is interpreted to be a fault ا wedge basin with the North Anatolian Fault̕s System Master Strand, namely the Gerede Fault, cutting across the basin itself. The basin and its surroundings contain mainly two groups of rock units namely the paleotectonic units and the neotectonic un...
Neotectonics and evolution of the Eskipazar Basin, Karabük ا Turkey
Biryol, C. Berk; Koçyiğit, Ali; Department of Geological Engineering (2004)
Study area, the Eskipazar Basin, is located in the western part of the North Anatolian Fault System. It is a 3-5 km wide, 10 km long and NWSE trending depression, bounded by a complex array of oblique-slip normal faults and strike-slip faults. The Eskipazar Basin is interpreted to be a superimposed basin. The basin fill is composed of two different units deposited under the control of different tectonic regimes, namely the paleotectonic and the neotectonic regimes. The latest paleotectonic fill of the basin...
Post miocene deformation of the area between Alibey (Kızılcahamam) and Karalar (Kazan) villages, nw Ankara (Turkey)
Karaca, Aykut; Rojay, Fuat Bora; Department of Geological Engineering (2004)
The study area is located within the Neogene-Quaternary sequences on top of the Mesozoic accreted mass at the northwest of Kazan (40 km NW of Ankara) between Karalar and Alibey villages. The research deals with the post-Miocene deformational history of an area situated at the southern edge of Galatian Volcanic Province. Two main Neogene rock sequences are cropped out; 1) Late Miocene Pazar Formation, 2) Plio-Quaternary Sinap Formation. The Pazar Formation has a succession composed mainly of clastics at the ...
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...
Assessment of slope stability for a segment (km: 25+600-26+000) of Antalya-Korkuteli highway
Arıkan, Huriye Aslı; Topal, Tamer; Department of Geological Engineering (2010)
The cut slopes at a segment between Km 25+600 and 26+000 of the Antalya-Burdur Breakaway-Korkuteli State Road to be newly constructed have slope instability problems due to the existence of highly jointed limestone. The purpose of this study is to investigate the engineering geological properties of the units exposed at three cut slopes, to assess stability of the cut slopes, and to recommend remedial measures for the problematic sections. In this respect, both field and laboratory studies have been carried...
