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. To put it simply, certain minerals quartz, feldspar, and calcite , store energy from the sun at a known rate. This energy is lodged in the imperfect lattices of the mineral's crystals. Heating these crystals such as when a pottery vessel is fired or when rocks are heated empties the stored energy, after which time the mineral begins absorbing energy again.

The equations used by scholars to determine the date when the last exposure happened are typically:.

ated August 24, Pottery : The most recent heating measured in pottery sherds is assumed to represent the manufacturing event; the signal arises from quartz or feldspar in the clay or other tempering additives. Although pottery vessels can be exposed to heat during cooking, cooking is never at sufficient levels to reset the luminescence clock.

Luminescence can also be used to determine the original firing temperature.

Absolute dating

Lithics : Raw material such as flints and cherts have been dated by TL; fire-cracked rock from hearths can also be dated by TL as long as they were fired to sufficiently high temperatures. The best success from TL dates on chipped stone artifacts likely are from events when they were deposited into a hearth and accidentally fired.

Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and.
