optically stimulated luminescence (OSL) dating
A comparatively new radiometric dating technique similar to thermal luminescence. OSL is based on the fact that minerals in sediment grains are affected by prolonged exposure to light. Specifically, light causes electrons of the mineral atoms to be progressively dislodged. This provides a natural clock. So far, the OSL technique has been used to date silty or sandy water deposited sediments that are 1/2 million years old or younger.
