Thermoluminescence dating of sediments Russian ault dating
Reliable age determinations can be obtained from 0.1ka to 200 ka. Equipment Our sample preparation laboratory is equipped with a magnetic separator and heavy liquid (sodiumpolytungstate) separation tools to isolate and clean the appropriate grain size fractions for each sample under darkroom conditions. Since a few years we shifted from thermal signal stimulation to optical stimulation and focussed our research on the applicabilty of the recently developed single aliquot dating procedures (SAR, SAAD). (2000) - The age and palaeo-environmental significance of the Kalahari sands in western Zimbabwe: a thermoluminescence study. We report here the TL dates for the baking by lava of clay and sediment, thereby avoiding the malign TL characteristics of the lava itself.The luminescence-dating laboratory was installed in 1993 as a collaboration between the Laboratory for Mineralogy and Petrology (Geological Institute) and the Laboratory of Analytical Chemistry (Institute for Nuclear Sciences, INW). When they are exposed to sunlight during transportation in the air the latent luminescence signal in the quartz and feldspar grains is bleached down to a negligible level and the luminescence "clock" is set to zero.(1998) The stratigraphy, sedimentology and thermoluminescence dating of the Upper Kalahari beds of western Zimbabwe.
