Coseismic Surface Deformation Analyses Using Sar And Optical Images: 2023 Kahramanmaraş Earthquake Sequence, Türkiye, Han-Kyung Bae, Gwang-Woo Oh, Jin-Hyuck Choi
Turkish Journal of Earth Sciences
The 2023 Kahramanmaraş earthquake sequence in Türkiye, including Mw 7.7 and 7.6 mainshocks, caused significant surface ruptures along the East Anatolian Fault (EAF) and Sürgü–Çardak Fault (SCF). We calculated the coseismic displacement fields through pixel offset tracking (POT) analysis of Sentinel-1 SAR data and optical image correlation (OIC) analysis of Sentinel-2 imagery. Our results reveal distinct sinistral motion along both the EAF and SCF, with maximum offsets of about 7 and 9 m, respectively. Deformation zones were identified both on and off the fault, highlighting the relationship between the rupture geometry and the broader deformation field. A comparative evaluation of …

Quick Antiquing Of Natural Stones In The Restoration Process, Hakan Elçi̇
Quick Antiquing Of Natural Stones In The Restoration Process, Hakan Elçi̇
Turkish Journal of Earth Sciences
When ancient buildings are restored, even though the restored section uses natural stone with the same lithological characteristics and texture as the building, there is a noticeable color difference between the restored and ancient portions of the building, signifying an old/new difference. This color difference, which is caused by the deterioration of the natural stone used in the ancient structure over many years, gives the natural stone a black or brown appearance. In this study, white marble, travertine, and sandstone were treated with antiquing techniques described in the literature. The goal was to identify the technique that produces the most …

A Model Study On Enhancing The Horizontal Gradient Of Potential Fields With The Vertical Derivative, Luan Thanh Pham, Saulo P. Oliveira, Erdi̇nç Öksüm, Jeferson De Souza
Turkish Journal of Earth Sciences
The total horizontal gradient (THG) and its derivatives are commonly used in interpreting potential fields. Because THG is a nonharmonic function, its vertical derivative (VD) can be consistently computed using, e.g., a finite-difference approximation. The calculation of VD in the wavenumber domain is physically meaningful for harmonic functions, but it provides a pseudovertical derivative (PVD) when applied to nonharmonic fields that can be used in some edge detectors, such as THG. Through experiments with synthetic and field datasets, we evaluated the performance of the PVD of THG in the tilt angle of THG (TAHG) and fast sigmoid-based edge detector (FSED). …

Turkish Journal of Earth Sciences
Although it is claimed that the same data was correctly attributed to Alçiçek (2007) in Elitez and Yaltırak (2023), no age data from Alçiçek (2007) were actually used in that study. In fact, the stratigraphic interpretation proposed by Alçiçek (2007) exhibits notable discrepancies with the conclusions presented by Elitez and Yaltırak (2023). Alçiçek (2007) defines the geological units overlying the basement as the Eşen Formation (comprising the Çetilidüz, Çaykenarı, and Kocaçay members) and Quaternary units. Based on the fossil Palaeotragus rouenii, the author suggests that the Neogene succession begins with Late Miocene alluvial-fan conglomerates, sandstones, and mudstones, whereas lacustrine sedimentation …

Citing The Citer: A Way To Claim Original Data, Mehmet Ci̇hat Alçi̇çek
Turkish Journal of Earth Sciences
In Elitez and Yaltırak (2024, p. 3), the “Upper Miocene” age data for the Eşen Basin fill is cited from Elitez and Yaltırak (2023). However, in that work, the same data was correctly attributed to Alçiçek (2007), which is the original source. Citing a secondary source instead of the original one is avoided in scientific writing. This letter aims to correct this citation practice.

Turkish Journal of Earth Sciences
In this study, we present petrographical and microanalytical (EPMA, LA–ICP–MS) results of apatites associated with Fe–Ti±P mineralization in the XV deposit in the BSMP. Apatite is predominantly observed as subhedral to euhedral, homogeneous grains, with no zoning or inclusions. Geochemically, apatite is fluorapatite of magmatic origin, with Cl/OH and Cl/F ratios of <0.05 and 0.01 to 0.07, respectively. Apatites from XV and other IOA deposits in the BSMP display a high F/Cl ratio, which is likely the main characteristic of IOA–type deposits such as the Kiruna-type deposit. Apatites from both rock types (gabbro and pyroxenite) exhibit similar rare earth elements (REEs) and multitrace element patterns, indicative of a shared origin. The highly light rare earth elements (LREEs)–enriched pattern in chondrite–normalized fractionation trends, along with positive Eu and slight negative Ce anomalies, as well the high (La/Sm)N and (La/Yb)N ratios of XV apatite, further corroborates the magmatic genesis of fluorapatite. The Eu/Eu* and Ce/Ce* ratios in XV rocks imply a high oxidation condition, as well as other IOA deposits in BSMP. The sulfur content is less than 1 wt% and shows a positive correlation with SiO2, implying coupled dissolution–reprecipitation of primary fluorapatite. Considering the geological setting of XV and other IOA deposits in the BSMP, the parental magma(s) appear to have originated from oxidizing Fe-Ti±P-rich magma(s), likely formed within an extensional postcollisional setting, influenced by the Proto–Tethys and Central Iranian Microcontinent (CIMC) convergence events.

The Neolithic lifestyle, which began in the 12th millennium BP with the emergence of villages in the core region extendingfrom Iran to central and southeastern Anatolia and Syria, began to spread to neighboring geographies, such as the Marmara region,in the 9th millennium BP. During the 8.2 ka event that occurred between 8300 and 7900 BP, cold and dry conditions prevailed in thenorthern hemisphere. During the winter months, the humidity decreased and cooling of about 6 ± 2 °C was observed. In order totest whether the 8.2 ka event was also effective in the İstanbul region, a set of inorganic geochemical …
