Optically stimulated luminescence (OSL) signals from quartz can be used to determine when sedimentary archives were deposited. OSL dating uses the accumulation of energy stored in a crystal structure measure time. This is absorbed ionizing radiation, and released (reset) by heat or daylight. The total specific (dose) since last resetting measured using OSL, divided rate storage (dose rate) give...

optically stimulated luminescence (osl) is currently one of the most important dating methods. it dates the last exposure to sunlight. natural hazard evidences such as colluvial wedges, alluvial and fluvial sediments can be dated by osl. therefore, osl plays an important role in studies related to paleoseismology and tectonic activity, particularly in arid and semi- arid regions. the altai moun...

Exploiting the luminescence signal stored in rock surfaces allows numerical dating of archaeological artifacts.
