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.the determination of the chronology of events studied from archaeological data.Two systems of archaeological dating are used: absolute and relative chronology.
The absolute dating method first appeared in 1907 with Lord Rutherford and Professor Boltwood at Yale University, but wasn’t accepted until the 1950s.
It was recovered in 1900–1901 from the Antikythera wreck, but its significance and complexity were not understood until a century later.
The Antikythera mechanism is an ancient analog computer designed to calculate astronomical positions.
This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.
The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.
Absolute chronology dates events in terms of the generally accepted calendar; relative chronology determines only the sequence of events.
