A New Look At The Origin Of N-S Trending Young Basins Of Western Anatolia, Ömer Feyzi Gürer
A New Look At The Origin Of N-S Trending Young Basins Of Western Anatolia, Ömer Feyzi Gürer
Bulletin of the Mineral Research and Exploration
In the western Anatolia, the tectonic regime transitioned from crustal shortening to extension during Late Cenozoic time and evidence of this event was imprinted on basement lithologies and N-S and E-W oriented two distinct basin sub-types. Here, we examined the exhumation mechanism of the Menderes massif that forms the basement of these basins from a different perspective. The N-S oriented basins overlying different basement rock types were re-evaluated based on new evidence that has potential to put new constrains for interpreting the tectonic evolution of the area. Unroofing of the Menderes Massif must have developed due to compressional core complex. …
Neogene Stratigraphy And Regional Correlation Of The Çeşme Peninsula, Western Anatolia, Turkey, Fikret Göktaş
Neogene Stratigraphy And Regional Correlation Of The Çeşme Peninsula, Western Anatolia, Turkey, Fikret Göktaş
Bulletin of the Mineral Research and Exploration
This study aims to investigate the stratigraphy and regional correlation of terrestrial Neogene sediments and volcanics in the Çeşme Peninsula. Neogene deposition is represented by two main sedimentary successions separated from each other by an angular unconformity. The lacustrine dominated Çeşme group characterized the Lower-Middle Miocene deposition is formed by Şifne, Ovacık and Çiftlik formations. The felsic pyroclastics (Alaçatı pyroclastics), which are the early products of the Armağandağı volcanism, laterally associated with the Çeşme group deposition, deposited on the Şifne formation and interrupted the lacustrine sedimentation. The lacustrine sedimentation continued uninterruptedly with Ovacık and Çiftlik formations after the deposition of …
An Overview Of The Current Seismicity Of The Sultandağı Fault Zone (Afyonkarahisar-Konya, Western Anatolia), Doğan Kalafat, Yavuz Güneş, Mehmet Kara, Kıvanç Kekovali
An Overview Of The Current Seismicity Of The Sultandağı Fault Zone (Afyonkarahisar-Konya, Western Anatolia), Doğan Kalafat, Yavuz Güneş, Mehmet Kara, Kıvanç Kekovali
Bulletin of the Mineral Research and Exploration
Western Anatolia is one of the most seismically active regions in Turkey. The high seismic activity is a result of a complex tectonic deformation dominated by the N-S extensional tectonic regime in Western Anatolia. This tectonic deformation is also a result of the relative movement of the African- Arabian plates towards the north, which causes the Anatolian plate to shift 2.5 cm per year towards W-SW. One of the largest fault zones in the Western Anatolia, Sultandağı Fault Zone (SFZ) has a northwest-southeast trend. SFZ, approximately 120 km long, is an important tectonic structure, which produced three major earthquakes (Mw …
Application Of Tilt Angle Method To The Bouguer Gravity Data Of Western Anatolia, Fikret Doğru, Oya Pamukçu, İlkin Özsöz
Application Of Tilt Angle Method To The Bouguer Gravity Data Of Western Anatolia, Fikret Doğru, Oya Pamukçu, İlkin Özsöz
Bulletin of the Mineral Research and Exploration
In this study, tilt angle method was applied to Western Anatolia gravity data in order to estimate edges of the geological structures. Tilt angle was obtained in two different ways by using gravity and its vertical derivative. In potential field methods, tilt angle technique is expressed as the ratio of vertical derivative to horizontal derivatives of anomaly. In the tilt angle map, 0° contours defines structure edges, half of the distance between ±45° defines depth of upper structure. In the field work of the study, gravity data, which was measured in Western Anatolia, was used to obtain regional anomaly maps …
Geochemical Characteristics And Rare-Earth Element Distributions Of Kozbudaklar W-Skarn Deposit (Bursa, Western Anatolia), Ayşe Orhan, Halim Mutlu
Geochemical Characteristics And Rare-Earth Element Distributions Of Kozbudaklar W-Skarn Deposit (Bursa, Western Anatolia), Ayşe Orhan, Halim Mutlu
Bulletin of the Mineral Research and Exploration
The Kozbudaklar W-skarn deposit occurs along the contact between Eocene Topuk Granitoid and Triassic İnönü Marble in Tavşanlı Zone. In the study area, the endoskarn is represented by plagioclase-pyroxene and exoskarn zone which is characterized by pyroxene, pyroxene-garnet, garnet and garnet-pyroxene skarn facies. According to major oxide element contents, exoskarn is of calcic character. In pyroxene and pyroxene-garnet skarn facies, tungsten and molybdenum abundances vary between 434-5507 ppm (mean 2330 ppm) and 8 - 90 ppm (mean 40 ppm). In the garnet and garnet-pyroxene skarns, concentrations of these elements are 271 - 7616 ppm (mean 2486 ppm) and 7 - …
