Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.This method includes carbon dating and thermoluminescence.The absolute dating method first appeared in 1907 with Lord Rutherford and Professor Boltwood at Yale University, but wasn’t accepted until the 1950s.The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.When museums and collectors purchase archaeological items for their collections they enter an expensive and potentially deceptive commercial fine arts arena.Healthy profits are to be made from illicitly plundered ancient sites or selling skillfully made forgeries.Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact's likely age.

This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.Limits to relative dating are that it cannot provide an accurate year or a specific date of use.The style of the artefact and its archaeology location stratigraphically are required to arrive at a relative date.
