Optically stimulated luminescence dating of young sediments a review
Burdur city is located on a lacustrine sedimentary deposit at the northeastern end of the Fethiye–Burdur Fault Zone (FBFZ) in SW Turkey.
Fault steps were formed in response to vertical displacement along normal fault zones in these deposits.
., 2004; Leopold & Völkel, 2007; Fuchs & Buerkert, 2008).
The major controlling factors behind whether a system is erosional or depositional are (i) the density and nature of vegetation cover (e.g., grassland versus forest), (ii) the amount and in particular the intensity of precipitation (i.e.
It is therefore necessary to understand why systems change their behaviour and one approach is to investigate its response to changes in the past.
In this context, an important issue regards the dating of hillslope and alluvial headwater deposits to allow the geological evidence to be placed into the regional evolution of climate and the history of human occupation.

Two short-lived phases of incision during the first half of the XIX century were probably caused by a decrease of sediment supply due to a decline in the frequency of heavy precipitation events.Two approaches result in OSL ages that are internally consistent and in excellent agreement with radiocarbon dating, indicating that all investigated sediments are younger than AD 1500.From this data a complex deposition and incision history is constructed for the last 500 years.The mineralogical features of the clays and age analysis of the liquefied materials were examined in the experimental studies.As a result of the X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM) micrographs, the liquefied clay mineral assemblage in the soil samples contains illite.
Deux approches conduisent à des âges OSL cohérents entre eux et bien corrélés à des dates radiocarbone.
