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 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.For example, JJA Worsaae used this law to prove the Three Age System.For more information on stratigraphy and how it is used in archaeology, see the Stratigraphy glossary entry.SAN FRANCISCO, March 23, 2010 -- Scientists today described development of a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage.

Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.

A professor emeritus at Texas A&M University College Station, Rowe teaches at a branch of the university in Qatar.

Traditional carbon dating involves removing and burning small samples of the object.

In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.

Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.
