Luminescence dating laboratory

For sediments some new problems were encountered, with some grains perhaps not being completely bleached at deposition.For OSL signals there is no simple procedure for the selection of a thermally stable signal, as there had been in the case of pottery.Luminescence Dating Laboratory Department of Geography University of Georgia GGY Building, Room 3AS Athens, GA, 30602-2502 Phone : 706-542-2322/2354 FAX : 706-542-2388 Director: George A. Brook WEBSITE: University of Georgia Luminescence Dating Laboratory began operations in early 2002.The lab has produced more than 300 OSL ages (from 140 years to 120,000 years) for aeolian, fluvial, lacustrine, and marine sediments, as well as pottery, artifacts and secondary carbonate. 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.

The laboratory has mainly RISØ equipment and OSL ages are obtained using the reliable single-aliquot, regenerative-dose (SAR) protocol.Luminescence dating, particularly using optically stimulated luminescence (OSL), is revolutionizing Quaternary and archaeological science because it allows dating of sediments and artifacts that perhaps 10 years ago could not be dated.It was purpose built and comprises rooms for sample preparation and measurement.In the last 30 years, from 1967 to 1997, the use of luminescence signals from naturally occurring minerals has gone though a major metamorphosis, from thermoluminescence (TL) dating of pottery to optically stimulated luminescence (OSL) dating of sediments.
