Relative dating in archaeology presumes the age of an artefact in relation and by comparison, to other objects found in its vicinity.Limits to relative dating are that it cannot provide an accurate year or a specific date of use.It is possible to tell the number of years ago a particular rock or archeological site had been formed.Two broad categories of classification methods are relative dating and absolute dating.When museums and collectors purchase archaeological items for their collections they enter an expensive and potentially deceptive commercial fine arts arena.
