An investigation for potential extensions of the Karaca Cavern using geophysical methods
(Springer, 2012)It is extremely important for regional tourism to determine the possible extensions of Karaca Cavern, one of the most important tourism destinations of the GumuAYhane province in Northeast Turkey. Cavities in karstic areas ... -
Investigation of the relationship among fault types, focal depths, and Ionospheric TEC anomalies before large earthquakes between 2000 and 2020
(ASCE- American Society of Civil Engineers, 2022)In this study, the relationships between possible ionospheric total electron content (TEC) anomalies and earthquake focal depths and fault types were investigated using 3,099 global earthquakes with Mw >= 6.0 between 2000 ... -
Late Jurassic Magmatism and Stratigraphy in the Eastern Sakarya Zone, Turkey: Evidence for the Slab Breakoff of Paleotethyan Oceanic Lithosphere
(Univ Chicago Press, 2017)Middle-Late Jurassic Cimmerian events in Turkey have been actively discussed in the past three decades, but proposed tectonic models associated with magmatism, metamorphism, and stratigraphic features remain controversial. ... -
Late Jurassic Paleotethyan oceanic slab break-off revealed by Sr-Nd-Hf isotopes of Na-rich adakitic granites from northwestern Turkey
(Elsevier, 2021)The Mesozoic geodynamic evolution of the Paleotethys Ocean is critical but a poorly known piece of the geological history of the Sakarya Zone, north Turkey. Here, we describe new integrated research of zircon U-Pb ... -
Latest Cretaceous "A(2)-type" granites in the Sakarya Zone, NE Turkey: Partial melting of mafic lower crust in response to roll-back of Neo-Tethyan oceanic lithosphere
(Elsevier Science Bv, 2018)An integrated study of comprehensive geochronological, geochemical, and Sr-Nd-Hf isotopic data was undertaken for the A-type Topcam pluton that intruded within the Sakarya Zone (NE Turkey) with the aims of elucidating its ... -
Melting of the juvenile lower crust in a far-field response to roll-back of the southern Neotethyan oceanic lithosphere: the Oligocene adakitic dacites, NE Turkey
(Elsevier, 2020)Late Cenozoic tectono-thermal events and associated magmatism in the Sakarya Zone (SZ) are still contested. Although documented in the western part of the SZ, thus far, no magmatic activity has been identified in the eastern ... -
