Advantages of absolute dating techniques in archaeology
Absolute dating can be achieved through the use of historical records and through the analysis of biological and geological patterns resulting from annual climatic variations, such as tree rings dendrochronology and varve analysis. Since the physical sciences contributed a number of absolute dating techniques that have had a revolutionary effect on archaeology and geology. These techniques are based upon the measurement of radioactive processes radiocarbon; potassium-argon, uranium-lead, uranium-thorium, thorium-lead, etc. Other techniques are occasionally useful, for example, historical or iconographic references to datable astronomical events such as solar eclipses archaeoastronomy. When archaeologists have access to the historical records of civilizations that had calendars and counted and recorded the passage of years, the actual age of the archaeological material may be ascertained—provided there is some basis for correlating our modern calendar with the ancient calendar. With the decipherment of the Egyptian hieroglyphics, Egyptologists had access to such an absolute timescale, and the age, in calender years, of the Egyptian dynasties could be established.

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. Archaeological scientists have two primary ways of telling the age of artefacts and the sites from which they came: Relative Dating In Archaeology Relative dating in archaeology presumes the age of an artefact in relation and by comparison, to other objects found in its vicinity.
