Özet:

 


Studies focusing on the Quaternary, the last period of the Earth’s history (~ 2.6 Ma) is involved with interaction of biosphere with significant earth processes such as climate changes, tectonic and volcanic activities.These studies are interdisciplinary in nature, which combines questions, techniques and methodologies of archeology, geology, paleoanthropology, geography and paleoseismology. In order to understand the main questions, such as “why”, “where” and “how” in earth processes, we consult physics and chemistry to answer the question “when”.  Fundamental sciences provide independent dating techniques to determine the exact timing and also rate of significant events. These techniques continuously develop by means of accuracy, integrity, sensitivity and also field of application.

One of the basic sources of information of these studies, inorganic sediments, are successfully dated by Optically Stimulated Luminescence (OSL) and Thermoluminescence (TL) methods for the Late Quaternary time interval (100200 ka). Recent developments in luminescence technique involves the study of formation of luminescence signal and nature of trap-charge structures in crystal lattice reveal possibility of dating older sediments deposited over million years ago.

In this study, we investigated the luminescence age of a high fluvial terrace in Kula (Manisa) Volcanic Field which is previously dated by constraining its deposition age with the radiometric dates of overlying lava flow (~1200 Ma) by employing Thermally Assisted (TA) OSL protocol. TA-OSL stimulates deeper traps than the ordinary OSL methods extending the age limit significantly. The result of TA-OSL age (1066±90 ka) coincides (88±10%) with the mean of radiometric dates (1200±22 ka), showing a promising success of a developing technique.
