Anthropology dating techniques

Luminescence dating is good for between a few hundred to (at least) several hundred thousand years, making it much more useful than carbon dating.

But when the rock is exposed to high enough levels of heat or light, that exposure causes vibrations in the mineral lattices and the trapped electrons are freed.

Luminescence dating (including thermoluminescence and optically stimulated luminescence) is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past.

The method is a direct dating technique, meaning that the amount of energy emitted is a direct result of the event being measured.

Better still, unlike radiocarbon dating, the effect luminescence dating measures increases with time.

As a result, there is no upper date limit set by the sensitivity of the method itself, although other factors may limit the method's feasibility.
