“…On the other hand, the luminescence centre responsible for the OSL emission at room temperature at 380 nm has been linked to an [AlO 4 ] o hole trap, based on a direct correspondence between the OSL signal intensity and the aluminium concentration in a synthetic crystal ; the emission peak in that study is similar to the peak at 365 nm observed for sedimentary quartz (Huntley et al, 1991). By necessity, it is this emission that is observed when optical stimulation is at 470 nm.…”

“…This combination restricts the detection window to ca. 350-400 nm, thus is centered on the main OSL emission of quartz (Huntley et al, 1991;Martini and Galli, 2007). Stimulation with IR laser diodes (850 ± 3 nm) was used to check for the purity of the quartz extracts.…”

Desert pavements are widespread landforms of arid environments. They consist of a monolayer of clasts at the surface, associated with an underlying unit of eolian fines. In some situations, buried desert pavements can be observed, which is interpreted as a change in the environmental conditions. Therefore, it is believed that desert pavements represent important paleoenvironmental sediment archives, especially for arid environments, where natural archives of past environments are rare. To better understand the formation process of desert pavements and to enable the paleoenvironmental interpretation of these valuable sediment archives, reliable chronologies are of crucial importance. Thus, OSL dating was applied to samples from well-developed desert pavements in two different study areas, the Cima Volcanic Field, eastern Mojave Desert, USA, and the desert of northeastern Badia, Jordan.To test the suitability of the sediments for OSL dating, the luminescence characteristics of the fine-and coarse-grain quartz fraction are described and compared. Finally, first OSL ages are presented.2

Abstract:This study presents test measurements on a Lexsyg luminescence reader, acquired by the Giessen luminescence group. The reader is of the type Standard, hence designed for routine determination of palaeodoses using quartz or K-feldspars. The tests include measurements of the stimulation powers, preheat temperatures, OSL-and TL-curves, as well as dose recovery tests and calibration measurements using highly sensitised calibration quartz. A comparison of D e values determined using a Lexsyg reader with single grain D e -values, which have been previously obtained on a Risø reader, is also presented. The results imply that the Lexsyg reader is a highly reliable measurement device with high reproducibility, yielding instrumental uncertainties of around 0.3%.
