Integrated fracture analysis for improved oil recovery in the reefal limestones of Soğucak formation, Northwest Thrace Basin, Türkiye
Karaca, Ergin; Yılmaz, İsmail Ömer; ÇİFCİ, GÜNAY; Tortopoğlu, Bulut; Akın, Serhat (2025-01-01)
Natural fractures play a crucial role in both exploration and development phases in oil and gas industry, as their network and orientation significantly affect flow and recovery strategies. This study highlights the import...
Helium and carbon isotope compositions of thermal fluids in the northeastern Anatolia: Implications for the heat source and volatile flux
AYDIN, HARUN; Karakuş, Hüseyin; MUTLU, HALİM; Güleç, Nilgün Türkan (2024-11-20)
In this study, we make a quantitative assessment on the volatile flux of mantle-derived fluids and source of volatiles to explain the geologic controls on the transport of volatiles within thermal fluids of northeastern An...

New evidence for a biostratigraphic assessment of the limestone succession comprising K-bentonite levels exposed in the Yilanli Formation of the Istanbul-Zonguldak Terrane are provided from conodonts at the Gavurpinari qua...
A time-space varying distributed unit hydrograph (TS-DUH) for operational flash flood forecasting using publicly-available datasets
Hu, Ying; Wu, Huan; Alfieri, Lorenzo; Gu, Guojun; Yılmaz, Koray Kamil; Li, Chaoqun; Jiang, Lulu; Huang, Zhijun; Chen, Weitian; Wu, Wei; Han, Qinzhe (2024-10-01)
Although flash floods originate in upstream (headwater) catchments causing hazards locally, they often occur at short time scales and affect widely while relatively small size catchments respond to intense rainfall systems...
A methodology providing new insights into the flow patterns of karst aquifers: an example from SW Türkiye
Maramathas, Athanasios; Katsanou, Konstantina; Sağır, Çağdaş; Baba, Alper; Lambrakis, Nikolaos (2024-10-01)
This paper presents a new and innovative methodology for the investigation of karst systems using spring discharge. The behaviour of springs in phase space is investigated by plotting the measurements of spring discharge v...
Significance of the Paleocene olistostrome–turbidite belt (Abant Formation) along the Intra-Pontide Suture, northern Turkey
Okay, Aral; Altıner, Demir; Özcan, Ercan; Hakyemez, Aynur (2024-09-02)
A belt of Paleocene turbidites with olistostromes, the Abant Formation, crops out for 350 km along the Intra-Pontide Suture in northern Turkey. The suture constitutes the contact between two major Pontide tectonic units, t...
Abrupt climate change at the MIS 5/4 transition recorded in a speleothem from the Eastern Mediterranean
Paine, Alice R.; Baldini, James U. L.; Ünal İmer, Ezgi; Wadsworth, Fabian B.; Iveson, Alexander A.; Humphreys, Madeleine C. S.; Brown, Richard J.; Mueller, Wolfgang; Ottley, Christopher J. (2024-09-01)
The marine isotope stage (MIS) 5a to 4 transition ( 74 ka) was associated with rapid ice sheet expansion, declining moisture availability globally, and significant upheaval of terrestrial ecosystems across the northern hem...
Block Rotations in NW Iran in Response to the Arabia-Eurasia Collision Constrained by Paleomagnetism
Niknam, Ali; van der Boon, Annique; Rezaeian, Mahnaz; Kaymakcı, Nuretdin; Langereis, Cor (2024-08-01)
Northwest Iran is a seismically active region dominated by NW-SE trending strike-slip faults, such as the North Tabriz and Qosha Dagh faults, and smaller NNE-SSW striking faults. The Bozgush Mountains are shaped by these f...
Deep Lithospheric Controls on Surface Deformation and Seismicity around the East Anatolian Fault Zone and A3 Triple Junction
Delph, Jonathan R.; Darin, Michael H.; Whitney, Donna L.; Cosca, Michael A.; Teyssier, Christian; Kaymakcı, Nuretdin; Eken, Tuna; Reid, Mary R.; Beck, Susan L. (2024-08-01)
The East Anatolian Fault Zone (EAFZ) is a plate-bounding strike-slip fault capable of hosting large earthquakes, as demonstrated by the extremely damaging February 2023 Mw 7.8 and Mw 7.7 mainshocks of the Kahramanmaraş ear...
Assessment of rarity and ecological preferences of the non-marine ostracods (Crustacea) in Çanakkale Province (Türkiye)
Yavuzatmaca, Mehmet; Külköylüoğlu, Okan; Ataman, Alper; Ayteğin, Ahmet; Yılmaz, İsmail Ömer (2024-07-01)
Rarity as a multidimensional concept has not been discussed for the ostracods along with the effects of physicochemical factors and sedimentation rates of waters on their distribution. We randomly sampled 91 aquatic sites ...

Güney Türkiye’nin Çangsingiyen karbonatlarından, yeni tür Glomomidiellopsis? okayi’yi de içeren, çok sayıda yeni foraminifer tanımlanmakta ve Orta-Geç Permiyen zaman dilimi içinde evrimsel kökenleri ve paleobiyocoğrafik da...
Delamination Magmatism in Eastern Anatolia: A Geochemical Perspective
Aktağ, Alican; Sayıt, Kaan; Furman, Tanya; Peters, Bradley J. (2024-05-01)
The Sr-Nd-Hf-Pb isotope geochemistry of the Late Miocene Tunceli Volcanics suggests that they are the products of mixed asthenospheric and lithospheric mantle melts. The combined elemental and mineral chemistry data additi...
