Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site. Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Stratigraphy is based on the law of superposition-like a layer cake, the lowest layers must have been formed first. In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers. Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.

Thermoluminescence Thermoluminescence (TL) dating is a technique that is based on the analysis of light release when heating crystalline material. TL-dating is used in mineralogy and geology, but is also increasingly being applied for dating of anthropological and archaeological samples. chlorophane mineral cool state heated Size: 1MB. Mar 07,   Thermoluminescence dating. Thermoluminescence (called TL) dating was invented around by physicists, and is based on the fact that electrons in all minerals emit light (luminesce) after being heated. It is good for between about to about , years ago, and is a natural for dating ceramic vessels. Aug 24,   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.

However, thermoluminescence proven acceptable in providing approximate dates in the absence of more exact measures. Sources: "Dating In Exposed and Surface Contexts", ed.: Beck, Charlotte.

Thermoluminescence dating definition, a method of dating archaeological specimens, chiefly pottery, by measuring the radiation given off by ceramic materials as they are heated. See more. Thermoluminescence dating is used mostly on pottery and other inorganic materials such as burnt flint. It's a very popular dating method in archaeology because not only can it date pottery, the type of material we find the most when excavating, but it can also date further back than 50, years unlike radiocarbon dating.

Because this accumulation of trapped electrons begins with the formation of the crystal structure, thermoluminescence can date crystalline materials to their date of formation; for ceramics, this is the moment they are fired. The major source of error in establishing dates from thermoluminescence is a consequence of inaccurate measurements of the radiation acting on a specimen.
