In this study paramagnetic centers in quartz minerals of Kumyer Location archeological samples were identified using Electron Spin Resonance (ESR) technique. ESR spectra were recorded at different microwave powers and various spectrometer temperatures with JEOL JESFa-300 X-band ESR spectrometer located in Selcuk University Advanced Technology Research and Application Center (İLTEK). It was determined that there is Al, Ti-Li, Ti-H and Ge paramagnetic centers which were produced by natural radiation in quartz minerals of ceramic samples and ESR parameters of these centers were measured. In order ...Daha fazlası
Archeological pottery is a good material that carries important data about ancient human life. Electron spin resonance (ESR) and optically stimulated luminescence (OSL) techniques are used for dating of a pottery found at Kumyer archeological site by rescue excavation from Muğla city in Turkey located at the western part of Anatolia. The ages estimated by ESR and by OSL methods are 4750±400 a and 4100±400 a, respectively, beinag consistent with an archeological analogical estimate of 3000–2000 B.C. In case of a broad signal overlapped with Al center, to take the frst peak is recommended as the ...Daha fazlası
The Konya Closed Basin is an important basin in central Turkey, in terms of its geographic position, Quaternary infills, and well-preserved archeological sites. It comprises Quaternary lake marls and other, mainly fine grained, sediments with locally in excess of 400 m. Geochemical data for samples taken from the 7-m-deep Adakale trench from the late Quaternary lacustrine sediments in the Konya Closed Basin are presented and have been used as proxies to elucidate the past climatic changes, weathering regime, redox conditions, and productivity. Climate changes observed in the studied samples fo ...Daha fazlası
Fossil mollusc shells are used for dating geological materials because they are well preserved throughout geological time. In this study, the radicals in the structure of fossil mollusc shells (Dreissena iconica, Valvata piscinalis, Bithynia tentaculate, Unio pictorum) collected from the Eastern Part of Old Konya Lake in Türkiye were investigated by EPR technique. For all fossil shells, microwave and temperature dependence of the signals were examined, and the signals suitable for dating are discussed. Characteristic features of intrinsic and impurity-related radicals were identified and the i ...Daha fazlası
