Using this technique, it is possible to date many samples from archeological sites, such as ceramics, brick, hearths, fire pits, kiln and smelter walls, heat treated flint or other heat-processed materials, sand and glass.

High vacuum TL oven is conceived to heat samples during thermoluminescence analyses.

Welcome to the USGS Luminescence Dating Laboratory Site.

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 DRILL research staff can collaborate on proposals, contribute to grant writing, and consult on study design.

We can also arrange training for undergraduate and graduate students, post-docs, and visiting researchers.

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.

Because of the somewhat short half-life of 14C, radiocarbon dating is not applicable to samples with ages greater than about 50,000 years, because the remaining concentration would be too small for accurate measurement.

In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly.
