The in situ natural radionuclide (U-238,Th-232 and(40)K) concentrations in Gumuhane granitoids: implications for radiological hazard levels of Gumuhane city, northeast Turkey
(Springer, 2019)
We have carried out 48 in situ measurements on radioactivities of U-238, Th-232 and K-40 isotopes at the Gumuhane granitoid plutons employing gamma-ray spectrometer with a NaI(Tl) scintillation detector. The radionuclide ...
Historical aurora borealis catalog for Anatolia and Constantinople (hABcAC) during the Eastern Roman Empire period: implications for past solar activity
(Copernicus Gesellschaft Mbh, 2020)
Herein, Anatolian aurorae are reviewed based on the existing catalogs to establish a relationship between the aurora observations and past solar activity during the Medieval period. For this purpose, historical aurora ...
In situ gamma ray measurements for deciphering of radioactivity level in Sarihan pluton area of northeastern Turkey
(Springer Heidelberg, 2017)
The present work utilizes in situ gamma ray spectrometric measurement data to map the surface geology of Sarihan Granitoid and its surrounding area. The study area comprises three different lithological units, namely, ...
Determination of Tectonic and Crustal Structure of the Eastern Pontide Orogenic Belt (NE Turkey) Using Gravity and Magnetic Data
(Springer Basel Ag, 2009)
The Eastern Pontide Orogenic Belt is one of the most complex geodynamic settings within the Alpine belt. Subduction polarity, which is responsible for the formation of the Eastern Pontide Magmatic Arc, is still under debate ...
Determination of the Crustal and Thermal Structure of the Erzurum-Horasan-Pasinler Basins (Eastern Turkiye) Using Gravity and Magnetic Data
(Springer Basel Ag, 2015)
The Erzurum-Horasan-Pasinler basin, which surrounds Miocene rocks, is oriented approximately E-W and is located in Eastern Anatolia (Turkiye). East Anatolia, where ophiolitic and young volcanic rocks are widespread, is ...
Crustal thermal properties of the Central Pontides (Northern Turkey) deduced from spectral analys of magnetic data
(2009)
Pontidler tektonik olarak Doğu, Batı ve Orta Pontidler olmak üzere üç ana bölgeye ayrılabilir. Bu birimlerin her biri okyanusal, kıtasal ve ada yayı parçalarından oluşan birleşik bir tektonik mozayiği göstermektedir. Doğu ...

Secular variation of magnetic declination for the past 500 years from Empire to Republic in Anatolia
(Elsevier B.V., 2022)
Seydi Ali Reis first mentioned the declination angle in his book titled Kitab-ı Muhit in 1554. Kitab-ı Cihannüma (1654), Füyuzat-i Mıknatisiye (1731), and Mârifetname (1757) gave the magnetic declination angle values in ...
Hydrocarbon reservoir depth identification in the eastern black sea basin: Implications from euler deconvolution and gravity tensor invariants
