Seeley M-A. Thermoluminescence testing involves heating a sample until it releases a type of light, which is then measured to determine the last time the item was heated. Luca does this area. Thermoluminescence dating was modified for use as a passive sand migration analysis tool by Keizars, et al. If you can measure the rate of acquisition of the stored energy, you can figure out how long it has been since the exposure happened.
TL dating method TL dating method consists of four major steps.
Unlike carbon datingluminescence dating methods do not require a contemporary organic component of the sediment to be dated; just quartz, potassium feldspar, or certain other mineral grains that have been fully bleached during the event being dated. Hidden categories: A disadvantage to this technique is that in order to get accurate results, the sediment to be tested cannot be exposed to light which would reset the "clock"making sampling difficult. Materials on the Quaternary Period of the Ukraine. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. Please help to improve this article by introducing more precise citations. In multiple-aliquot testing, a number of grains of sand are stimulated at the same time and the resulting luminescence signature is averaged .
