The correlation of fast OSL component with the TL peak at 325 degrees C in quartz of various origins
(Elsevier Science BV, 2010-02)The fast component of the optically stimulated luminescence (OSL) signal in quartz is the basic tool for the optical dating. Its relation with the thermoluminescence (TL) glow-peak at about 325 degrees C is well established ... -
Dissolution and subsequent re-crystallization as zeroing mechanism, thermal properties and component resolved dose response of salt (NaCl) for retrospective dosimetry
(Pergamon-Elsevier Science Ltd, 2011-09)In the present study we report dosimetric properties of iodized salt aiming at using it as an accidental luminescent dosimeter. It was found that the very good sensitivity of its main dosimetric peak is strongly affected ... -
Equivalent dose in quartz from young samples using the SAR protocol and the effect of preheat temperature
(Pergamon-Elsevier Science Ltd, 2006-09)Major concerns in the dating of samples younger than a few hundred years by the optically stimulated luminescence (OSL) technique are thermal transfer and partial bleaching. Thermal transfer during preheating enhances the ... -
In-homogeneity in the pre-dose sensitization of the 110 degrees C TL peak in various quartz samples: The influence of annealing
(Elsevier Science BV, 2012-03-01)The pre-dose sensitization effect of the 110 degrees C TL glow-peak of quartz is a basic tool in thermoluminescence and optically stimulated luminescence dating and retrospective dosimetry. In the present work, a homogeneity ... -
Investigation of OSL signals from very deep traps in unfired and fired quartz samples
(Elsevier Science BV, 2010-03-15)This paper presents an attempt to isolate experimentally optically stimulated luminescence (OSL) signals which may originate from very deep traps (VDT) in quartz samples. As VDT we consider those traps which are responsible ... -
A new late holocene eolianite record from Altinkum Beach, North Cyprus
(Scientific technical research council Turkey-Tubitak, 2012-06)In this study, we investigated the main depositional characteristics and obtained Optically Stimulated Luminescence (OSL) ages of coastal eolianite on the north coast of Cyprus, where this occurrence had not previously ... -
Optical stimulated luminescence dating study of eolianite on the Island of Bozcaada, Turkey: Preliminary results
(The Coastal Education and Research Foundation, 2010-07)In the present paper, eolianite exposed on the south coast of the semiarid island of Bozcaada, Turkey, was investigated on the basis of geomorphologic and petrographic data, and optically stimulated luminescence (OSL) ... -
Quaternary rock uplift rates and their implications for the western flank of the North Anatolian Fault restraining bend; inferences from fluvial terrace ages
(Blackwell Publishing Ltd, 2020-10-01)In the western flank of the North Anatolian Fault restraining bend (i.e., Central Pontides), the Filyos River incises through the uplifting Karabük Range, creating the ~1.7-km-deep Filyos River Gorge on the hanging wall ... -
Relative response of TL and component-resolved OSL to alpha and beta radiations in annealed sedimentary quartz
(Pergamon-Elsevier Science Ltd, 2011-10)Knowledge of the relative luminescence response to alpha and beta radiation is very important in TL and OSL dating. In the present study the relative alpha to beta response is studied in a sedimentary quartz sample, ... -
Tectonic and climatic controls on Quaternary fluvial processes and river terrace formation in a Mediterranean setting, the Goksu River, southern Turkey
