Thermal luminescence dating

Read More Luminescence dating has been instrumental in constraining the age of archaeological and human skeletal remains.

Thermoluminescence dating was applied originally to heated pottery and burnt flint, and optical dating was developed subsequently to estimate the depositional age of sun-bleached sediments associated with artefacts and fossils.

Importantly, luminescence dating covers an age range that spans the last several decades to the last several hundred thousand years, providing critical rates and dates for evaluating processes that are important to society.

Read More Luminescence dating relies on the fact that mineral grains (crystals) are exposed to sources of natural radiation, which causes charge to be stored in electron traps within the crystal lattice.

A amostragem compreende sedimentos eólicos costeiros do Holoceno tardio () as a method to determine the firing age of archaeological ceramic materials.

Since this benchmark work, many studies aimed to develop protocols for dating the firing age of archaeological materials (ceramics and bricks), formation age of meteorites and burial age of sediments using thermoluminescence (TL) signals.

Initial studies using TL dating of sediments commonly were showing age overestimation compared to other independent age controls such as radiocarbon.

This was ascribed to the difficulty of measuring an optically reset luminescence signal (in the environment) by a thermoluminescence approach. The alpha effectiveness in silt-sized quartz: New data obtained by single and multiple aliquot protocols.
