Aitken science based dating in archaeology

Some soils can have their electron 'clocks' reset simply by being exposed to sunlight.

If they are then buried beneath later deposits, they begin to trap electrons again and can be dated by similar methods (OSL).

Archaeometry has greatly influenced modern archaeology. Archaeologists can obtain significant additional data and information using these techniques, and archaeometry has the potential to revise the understanding of the past.

Archaeological science, also known as archaeometry, consists of the application of scientific techniques to the analysis of archaeological materials, to assist in dating the materials. In the United Kingdom, the Natural and Environmental Research Council provides funding for archaeometry separate from the funding provided for archaeology.

Another important subdiscipline of archaeometry is the study of artifacts.

Part of this is the ordinary glow of burning, the remainder is due to escape of these trapped electrons and this is measured.

These techniques can date objects up to 50,000 years old, although both are more accurate within the past 10,000 years.

Some natural materials such as various stones and soils (and also things made from them, such as pottery and stone tools) absorb or 'trap' naturally occurring electrons from their surroundings.
