Luminescence methods provide the age of archaeological sites or objects
Rocks containing amorphous/microcrystalline SiO2 can be dated by luminescence methods when they have been heated to approximately 400°C.
Archaeological sites often contain teeth from animals or humans or the site is contained in quartz bearing sediment. The enamel can be dated with Electron Spin Resonance (ESR or EPR), but it is often required to combine this method with U-series dating.
Optically Stimulated Luminescence (OSL) as well as Thermoluminescence (TL) can be applied to heated objects made from clay.
When sediments cover an archaeological site they are exposed to light and the mineral grains are bleached. Such events can be dated by luminescence methods and the age employed to determine the age of an archaeological site through its related sediments.
The exposure to light zeroes the signal employed in luminescence dating. The dated event is the last light exposure which allows establishing the time of site abandonment, object use/displacement, erection and destruction of walls, etc.
