Luminescence dating limitations

Stimulating samples using infrared light causes luminescence, the intensity of which varies depending on the amount of radiation absorbed.

Exposure to sunlight resets the luminescent signature and so the time period since the sediment was buried can be calculated.

The sample is taken by introducing the tube into a freshly cleaned back surface; if this proves difficult a block may be cut from the unit of interest.

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

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.

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.
