Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history.Chronometric techniques include radiometric dating and radio-carbon dating, which both determine the age of materials through the decay of their radioactive elements; dendrochronology, which dates events and environmental conditions by studying tree growth rings; fluorine testing, which dates bones by calculating their fluorine content; pollen analysis, which identifies the number and type of pollen in a sample to place it in the correct historical period; and thermoluminescence, which dates ceramic materials by measuring their stored energy.

Dating is very important in archaeology for constructing models of the past, as it relies on the integrity of dateable objects and samples.

Many disciplines of archaeological science are concerned with dating evidence, but in practice several different dating techniques must be applied in some circumstances, thus dating evidence for much of an archaeological sequence recorded during excavation requires matching information from known absolute or some associated steps, with a careful study of stratigraphic relationships.

The stratigraphy of an archaeological site can be used to date, or refine the date, of particular activities ("contexts") on that site.

For example, if a context is sealed between two other contexts of known date, it can be inferred that the middle context must date to between those dates.

For example, in a stratum presenting difficulties or ambiguities to absolute dating, paleopalynology can be used as a relative referent by means of the study of the pollens found in the stratum.

This is admitted because of the simple reason that some botanical species, whether extinct or not, are well known as belonging to a determined position in the scale of time.That means that the play was without fail written after (in Latin, post) 1587.The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.In addition, because of its particular relation with past human presence or past human activity, archaeology uses almost all the dating methods that it shares with the other sciences, but with some particular variations, like the following: Seriation is a relative dating method (see, above, the list of relative dating methods).An example of a practical application of seriation, is the comparison of the known style of artifacts such as stone tools or pottery.The Institute advances awareness, education, fieldwork, preservation, publication, and research of archaeological sites and cultural heritage throughout the world. When you join the Archaeological Institute of America, you’ll be joining a group of individuals passionate about archaeology, protecting the world’s cultural heritage, and disseminating archaeological research.
