Typically OSL techniques produce ages from one or two hundred years to about 400 ka with an error of around 10%.
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 majority of sediment dating applications are carried out on quartz and potassium-rich feldspars and the general characteristics of the TL and OSL signals from these minerals are reviewed.
For sediments some new problems were encountered, with some grains perhaps not being completely bleached at deposition.
We are also equipped to measure Infrared Stimulated Luminescence (IRSL) on potassium feldpsar.
Please explore the 'Projects' and 'Publications' pages for examples of internal and external projects that the Lab has been involved with.
This trapped signal is light sensitive and builds up over time during a period of no light exposure (during deposition or burial) but when exposed to light (natural sunlight or artificial light in a laboratory) the signal is released from the traps in the form of light – called luminescence.TALKS - Kirk Townsend* and Tammy Rittenour, Episodic arroyo entrenchment and aggradation in Kanab Creek, Southern Utah Tammy Rittenour* et al., Single-grain OSL chronology of ice retreat and stages of Glacial Lake Benson, west-central Minnesota, USA Kerry Riley* and Tammy Rittenour, Mid-late Holocene arroyo cut-fill dynamics: Hydro-climate and complex inter-basin response POSTERS - 214-3: Kerry Riley* and Tammy Rittenour, Erosion rates influence arroyo cut-fill dynamics in semi-arid catchments draining the Grand Staircase region of Colorado Plateau 312-3 : Michelle Nelson* and Tammy Rittenour, Best practices for collection of luminescence samples and estimating water content for dose-rate determination: Why sample selection, collection technique and water content matters 312-6: Tammy Rittenour* et al., How old are the SP and Strawberry volcanic vents and flows in the San Francisco Volcanic Field, Arizona?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. 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.The DRILL welcomes collaboration with research institute and university faculty, consultants, and government agency researchers.After deposition these sediments accumulate luminescence which can be measured allowing the age of burial to be determined.
