Optically stimulated luminescence dating

Resultaten visar att det förekommit fem episoder av flygsandavsättning.

Den äldsta händelsen var efter isavsmältningen vid ca 15 200 år sedan.

Twelve samples for OSL measurement, two samples for 14C and ten samples for grain size analysis were collected.

(More)Wind is an important agent of transportation of sediments and to change the landscape.

The main aim of this study was to determine the timing of aeolian sand deposition and to relate it with past climate and environment.

The oldest event recorded during this study was after deglaciation at ca.15 200 a. 14 500 to 13 000 a and the last date obtained in this event is at the beginning of the Younger Dryas. 1900 - 1700 a at the time of the Roman warm period. 400 - 300 a and the fifth or latest episode was at ca. The first episode was deposited right after deglaciation and the remaining four episodes were deposited probably due to climatic impact such as strong storminess or by human activities.

Tolv prover för OSL-datering, två prover för C14-datering och tio prover för kornstorleksanalys har tagits från området för rekonstruktion av flygsandfältets bildningshistoria.

I den här studien har ett flygsandfält i Blentarp, södra Sverige undersökts.

The time elapsed since sedimentation, i.e., Age = Paleodose Annual Dose In practice, the paleodose is calculated by measuring the luminescence intensity in the natural mineral and regenerate the equivalent luminescence intensity by artificial radiation dose from a calibrated beta source attached to the TL/OSL instrument.

For calculating the annual dose rate, the elemental concentration of U, Th and K (by XRF or ICP-MS) in the sediment and water content in the sediment are required.
