Luminescence dating limitations

The basic cost is £550/sample plus reporting time based on your requirements.

The report will contain OSL results calibrated for sample water content and salinity.

Thermoluminescence (TL) dating is now widely used in the age determination of Paleolithic sites.

Although the basic principle of TL-dating is simple, the underlying assumptions are not trivial.

One major source of error is the external dose rate, which contributes to a varying degree to the denominator of the age formula and thus has a varying influence on the dating result.

The intention of this paper is to enable the user to evaluate TL age determinations of heated flint.

The limitations of the method as well as the advantages are discussed.

The specimen tube or block should then be wrapped in black plastic to prevent further exposure to light and to preserve the environmental moisture content.

Thermoluminescence (TL) dating of sediments depends upon the acquisition and long term stable storage of TL energy by crystalline minerals contained within a sedimentary unit.

This energy is stored in the form of trapped electrons and quartz sand is the most commonly used mineral employed in the dating process.

Numerical dating of loess is important for Quaternary studies.

Recent progress in post-infrared infrared-stimulated luminescence (p IRIR) signals from potassium-rich feldspar has allowed successful dating of Chinese loess beyond the conventional dating limit based on quartz optically stimulated luminescence (OSL) signals.
