(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.Both coarse- and fine-grained material can be used for dating.

Den första episoden skedde direkt efter isavsmältningen och de återstående fyra orsakades troligen av mänsklig aktivitet eller klimatpåverkan som OSL dating can be used to determine the time since naturally occurring minerals, such as quartz and feldspar, were last exposed to light within the last few hundreds of thousands of years.

Det finns en uppfattning om att flygsanden avsattes direkt efter inlandsisens avsmältning och att den reaktiverades i historisk tid som ett resultat av mänsklig påverkan och klimatförsämring.I den här studien har ett flygsandfält i Blentarp, södra Sverige undersökts.Tolv prover för OSL-datering, två prover för C14-datering och tio prover för kornstorleksanalys har tagits från området för rekonstruktion av flygsandfältets...Depending on the type of stimulation source, the phenomenon is termed thermally stimulated luminescence (TL) or optically stimulated luminescence (OSL).The OSL is further divided, based on the colour (wavelength) of the excitation light source, into Blue Light Stimulated Luminescence (BLSL) and Infrared Stimulated Luminescence (IRSL)Luminescence dating requires a proper resetting of the previously acquired (pre depositional) luminescence in the natural minerals into a very low level (natural zeroing event), either by exposure to sun light during pre-depositional transportation (by wind, water etc.) or by a thermal event (pottery making, baking by lava, fusion crest of meteorites), before deposition.

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