The most suitable type of sample for thermoluminescence dating is pottery, though the.
The luminescence dating facilities consist of three purpose-built laboratories: two self-contained sample preparation rooms, which operate under carefully controlled dim-red lighting conditions, and an instrument facility for undertaking OSL, IRSL and TL measurements and determining De estimates of samples.
Quartz and feldspars produce optically stimulated luminescence (OSL).
The DRILL welcomes collaboration with research institute and university faculty, consultants, and government agency researchers. Welcome to the USGS Luminescence Dating Laboratory Site. 1, Annual Review of Earth and Planetary Sciences, 3.
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 OSL signal is dependent upon the period of time that has passed since the mineral grain was last exposed to sunlight, and/or the period of time that the mineral has been held at an ambient temperature of ≤ 30 °C.
Optically stimulated luminescence is a versatile technique which can be used to determine the age of a depositional feature such as a glacial moraine (OSL dating) or alternatively the erosion and/or uplift rate of a mountain (OSL thermochronology).
We can also arrange training for undergraduate and graduate students, post- docs, and visiting researchers. Chart showing number of documents tagged with luminescence dating keywords over time. For very detailed information on luminescence dating, read.

This allows researchers to date materials that cannot be dated using other techniques (e.g., lack of suitable organic remains for radiocarbon dating).
Additionally, since it is capable of directly dating cultural materials such as ceramics, the bridging arguments between dating events and target events are minimized.
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.
