“…In this context while the paleomagnetic properties of the young volcanics point to the block rotations [eg. 18,19], the strikes of the fissure-ridge travertines can delineate the stress tensor rotations as a significant tool or indicator in Neotectonic periods.…”

Travertines exposed in several locations in Central Anatolia are the important lithological product for the interpretation of local neotectonics. The fissure-type travertines provide significant information about stress orientation during deposition. Two travertine masses cropping out in the Kırşehir region have been studied and dated by the U-series method to obtain new chronological constraints, determine dilation rates and contribute to studies on the recent tectonic evolution of the area. The Kuşdili and Kayabaşı travertine masses are located on the hanging wall of the Kırşehir Fault, similar to numerous fissure ridge banded travertine deposits which are inactive today in the region. While individual fissures of the Kuşdili travertine mass (Late Pleistocene-Holocene) have been dilated at rates of between 0.303 and 0.386 mm yr -1 during deposition, the Kayabaşı travertine mass (Late Pleistocene) produced measured dilation rates of between 0.136 and 0.187 mm yr -1 . The central fissures, filled by banded travertine, roughly follow the ridge crests. While the ridge crest has a NNE-SSW trend in the Kayabaşı travertine mass, the ridge crest of the Kuşdili travertine mass shows a NE-SW trend. This difference may be related to the clockwise rotation of the stress tensors from Late Pleistocene to Late Pleistocene-Holocene in the region.

The Tuzgolu Basin is the largest basin in Central Anatolia. It is connected to the Haymana Basin by a small channel-shaped basin called the Tersakan Basin. The study area has smooth topography with a stable young sedimentary cover and limited outcrop zones, but displays a complex geology with intense active tectonism and poor seismic quality beneath the surface. In the study reported here an attempt was made to determine the subsurface structure of the basement by three-dimensional modelling of gravity data. The seismic and magnetic data were also integrated with the available geological data to check the modelling results. The modelling results suggest that the deeper parts of the Haymana Basin are located to the east of Haymana city centre, at a maximum depth of 8 km, with the exception of the depression to the north, which is located 25 km northwest of Bala city centre at a maximum depth of 10 km. The channel-shaped Tersakan Basin (connecting the Haymana and Tuzgolu Basins) is located west of Lake Tuzgolu, and the deepest part of this basin is approximately 5.5 km. The Tuzgolu Basin has three major depressions: (1) the Southern Aksaray Depression, which is covered by younger volcanic rocks, is the largest but in general the least explored area; (2) the Eregli Depression; (3) the Sultanhani Depression. Almost all of these depressions have an average depth of 8 km; however, some of the deeper segments are at a depth of approximately 12-13 km. Our results suggest the possibility of hydrocarbon potential in these basins.

“…This fault zone has the characteristics of the right-lateral strike-slip fault that is NW-SE trend, 30 km long and lies between Yerköy and Şefaatli (Koçyiğit, 2003 (Arni, 1938;Parejas ve Pamir, 1939) and the focal mechanism solutions of the earthquake indicated the right-lateral strike-slip faulting and the approximate direction of NNW-SSE compressive stress (Jackson and McKenzie, 1984;Canıtez and Büyükaşıkoğlu, 1984). It was seen that NW-SE directional compressive stress was effective in the focal mechanism solution of Hacıduraklı-Çiçekdağı earthquake on 10 January 2016 and NE-SW directional one was effective in the tensile stress (AFAD-DDB) (Figure 2 (Tatar et al, 1996, 2000, 2002, Gürsoy et al, 1997, 1998, 1999, 2003.…”

ÖZSismik etkinlik bakımından sakin bir bölge olarak bilinen Orta Anadolu'da 10 Ocak 2016 günü, yerel saat ile 19.40'da merkez üssü Kırşehir ili Çiçekdağı ilçesi Hacıduraklı köyü olan 5.0 (M w ) büyüklüğünde bir deprem meydana gelmiştir. Depremin odak mekanizması çözümü, sağ yanal doğrultu atımlı bir faylanmayı göstermektedir. Bu depremin, odak mekanizması çözümü ile uyumlu olan ve iki yapısal segmentten oluşan ve sağ yanal doğrultu atımlı Manahözü Fayının BKB-DGD uzanımlı segmenti ile ilişkili olarak meydana geldiğini göstermektedir. Manahözü Fayı aktif bir fay olup bölgenin son dönem yapısal olarak şekillenmesinde rol oynayan önemli yapılardan biridir. Kırşehir ve yakın civarındaki önemli jeolojik yapılardan bir diğeri ise, sağ yanal doğrultu atımlı ve KB-GD uzanımlı Seyfe Fay Zonu'dur. Bu aktif yapılar arasındaki etkileşim Seyfe çek-ayır havzasının oluşmasına neden olmuştur. Ayrıca, Manahözü deresinin kuzeyindeki yükselimin Manahözü Fayı ve Yerköy Fay Zonu arasındaki birleşme nedeniyle olabileceğini düşündürmektedir. Aktif bir yapı olan Manahözü Fayının KB-GD uzanımlı segmenti de gelecekte deprem üretme potansiyeline sahip bir yapı olarak durmaktadır.
