Heating an item to degrees Celsius or higher releases the trapped electrons , producing light.

This light can be measured to determine the last time the item was heated. Radiation levels do not remain constant over time. Fluctuating levels can skew results — for example, if an item went through several high radiation eras, thermoluminescence will return an older date for the item.

Many factors can spoil the sample before testing as well, exposing the sample to heat or direct light may cause some of the electrons to dissipate, causing the item to date younger. It cannot be used to accurately date a site on its own. However, it can be used to confirm the antiquity of an item.

Optically stimulated luminescence OSL dating constrains the time at which sediment was last exposed to light. During sediment transport, exposure to sunlight 'zeros' the luminescence signal. Upon burial, the sediment accumulates a luminescence signal as natural ambient radiation gradually ionises the mineral grains.

Careful sampling under dark conditions allows the sediment to be exposed to artificial light in the laboratory which releases the OSL signal. The amount of luminescence released is used to calculate the equivalent dose De that the sediment has acquired since deposition, which can be used in combination with the dose rate Dr to calculate the age. Dendrochronology or tree-ring dating is the scientific method of dating based on the analysis of patterns of tree rings , also known as growth rings.

Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year. Dendrochronology has three main areas of application: paleoecology , where it is used to determine certain aspects of past ecologies most prominently climate ; archaeology , where it is used to date old buildings, etc. In some areas of the world, it is possible to date wood back a few thousand years, or even many thousands.

Currently, the maximum for fully anchored chronologies is a little over 11, years from present. Amino acid dating is a dating technique [5] [6] [7] [8] [9] used to estimate the age of a specimen in paleobiology , archaeology , forensic science , taphonomy , sedimentary geology and other fields. This technique relates changes in amino acid molecules to the time elapsed since they were formed. All biological tissues contain amino acids.

All amino acids except glycine the simplest one are optically active , having an asymmetric carbon atom. This means that the amino acid can have two different configurations, "D" or "L" which are mirror images of each other. With a few important exceptions, living organisms keep all their amino acids in the "L" configuration. When an organism dies, control over the configuration of the amino acids ceases, and the ratio of D to L moves from a value near 0 towards an equilibrium value near 1, a process called racemization.

Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died. From Wikipedia, the free encyclopedia. Main article: Radiometric dating. Main article: Radiocarbon dating. Main article: Potassium—argon dating. Main article: Luminescence dating.

is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating. Relative vs. Absolute Dating.
