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.
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. Fw-300 .qstn-title #ya-trending-questions-show-more, #ya-related-questions-show-more #ya-trending-questions-more, #ya-related-questions-more /* DMROS */ .A method is described which allows the determination of radiation doses received by mineral grains since their last exposure to sunlight, even if this exposure was of relatively short duration or through a poorly transmitting medium.Laschamp and Olby flows of the Chaîne des Puys in the French Massif Central, was frustrated by anomalous fading of the TL.This anomalous fading seems to be exhibited by most of the TL-sensitive minerals in lava and is probably due to wave mechanical leakage of electrons out of traps to nearby defects way of using traps that are immune to anomalous fading, it has not yet proved possible to obtain TL dates directly from volcanic lava (although an empirical technique has achieved relative dating in one particular application).
