Relative chronometric dating methods

deposit and can be no alter (no more recent) than the deposit itself Allows to date a field site by dating an artifact because of association Nitrogen, fluorine, uranium, collagen content, gradually reduced by process of chemical decay. Very variable, depends on site's chemical content as well.Cannot form a basis of absolute dating, but on an individual site, chem, dating can distinguish bone on different age found in apparent stratigraphic association Duration of different artifact styles that governs seriation Artifacts are arranged acc.Without the ability to date archaeological sites and specific contexts within them, archaeologists would be unable to study cultural change and continuity over time.No wonder, then, that so much effort has been devoted to developing increasingly sophisticated and precise methods for determining when events happened in the past.

The oldest strata are at the bottom of the sequence.For example, the results of dendrochronology (tree-ring) analysis may tell us that a particular roof beam was from a tree chopped down in A. For example, the stratum, or layer, in which an artifact is found in an ancient structure may make it clear that the artifact was deposited sometime after people stopped living in the structure but before the roof collapsed.However, the stratigraphic position alone cannot tell us the exact date.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.
