Many different laboratory protocols have been developed as our understanding of the fundamental behaviour of luminescence signals from quartz and feldspar has improved.
These protocols are explained and discussed, giving the advantages and disadvantages of each procedure as applied to different types of sediment.
Please see the links at left for more information about luminescence and the DRILL.
The DRILL is a research laboratory dedicated to fundamental investigations in the luminescence properties of earth materials and to the application of luminescence dating techniques to geomorphological, geological, and archeological problems.
Cord Luminescence Laboratory (DRILL) is located at DRI’s northern campus in Reno, NV and offers a broad spectrum of luminescence dating capabilities including optically stimulated luminescence (OSL) and thermoluminescence (TL) techniques.
As the OSL of a sediment is quickly lost when exposed to sunlight (tens of seconds) many sediments are bleached (lack an OSL signal) when deposited and buried.
After deposition these sediments accumulate luminescence which can be measured allowing the age of burial to be determined.
