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.
