Alaşehir Type - Rolling Hinge Mechanism In The Northern Margin Of Büyük Menderes Graben: Evidence From Seismic Reflection And Recent Thermochronological Data, Fevzi̇ Mert Türesi̇n, Gürol Seyi̇toğlu
Turkish Journal of Earth Sciences
Isotopic and thermochronological data were recently obtained from the footwall of the Büyük Menderes detachment ranges from 29.0 ± 1.9 Ma (ZFT) to 1.6 ± 0.2 Ma (Ap U - Th / He), and they can be grouped in three different time intervals. These results are well explained by the Alaşehir type-rolling hinge mechanism, which suggests active rotated initial normal fault during successive normal fault development of the graben formation. This paper suggests that the Alaşehir type-rolling hinge mechanism is applicable to the Büyük Menderes graben by using field observations, published isotopic / thermochronological and subsurface data. It also contributes …

South Western Anatolia is dominated by E-W and NW-SE trending active faults. The dip-slip Yatağan Fault is one of these active structures that trends in a NW direction for ~30 km. To assess the relative tectonic activity of the Yatağan Fault, two geomorphic segments were defined along the fault: the FS-1 (northern segment) and the FS-2 (southern segment). The vertical slip rate pattern of the fault was analyzed using steepness indexes, chi (χ) plots, and log-log slope area graphs. Results of the analyses indicate that the steepness of the streams draining the footwall reveal increasingly higher values downstream along the …

Structural Characteristics Of Transtensional Fault System And Its Implication Forhydrocarbon Accumulation In S Block, South Asia Area, Yuwen Dong, Iftikhar Satti, Maman Hermana, Xu Chen
Turkish Journal of Earth Sciences
Transtensional faults are well developed in the S Block of the South Asia area, which have an important impact on the hydrocarbon accumulation. However, the transtensional fault structure is very complex. Based on drilling and seismic data interpretation results, faults are divided into three typical types in the Lower Cretaceous, which can help to understand the complex fault system. The main faults are distributed in the NNW-SSE direction and parallel arrangement with dextral strike-slip shear characteristics, which determines the development of the tectonic belt. The secondary faults are often associated with the main faults, often composed of multiple branch faults. …

Geothermal Reservoir Rocks Of The Büyük Menderes Graben (Turkey): Stratigraphiccorrelation By A Multiproxy Approach, Dorothee Siefert, Markus Wolfgramm, Thomas Koelbel, Johannes Glodny, Jochen Kolb, Elisabeth Eiche
Turkish Journal of Earth Sciences
This paper focuses on the correlation of two different marble units from an approximately 3,900 m deep geothermal exploration well (GP-1) in western Turkey by petrographical and geochemical data. Future geothermal exploration drilling in that area will benefit from a better (tectono) stratigraphic correlation and a better definition of the reservoir geometry in the basin. It is an innovative approximation in many settings to correctly correlate marble units without clear stratigraphic markers or fossil record, in particular, when sample material is restricted to cuttings. The most distinctive petrographical and geochemical properties in this study are colour, light transmission along with …
