Radiocarbon dating thermoluminescence archaeology

It is based on the knowledge that living organisms build up their own organic matter by photosynthesis or by using atmospheric carbon dioxide.

A number of methods are used, all of which have their advantages, limitations and level of accuracy.

Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology.

On the other hand, absolute dating includes all methods that provide figures about the real estimated age of archaeological objects or occupations.

This applies the geological principle that under normal circumstances younger layers of sediment will be deposited on top of older layers.

This 'law of superimposition' works in the well-defined layers of the Willandra lunettes, but only dates objects as younger or older than adjacent layers.

It is possible then to calculate the date of an organic object by measuring the amount of C14 left in the sample.

For those researchers working in the field of human history, the chronology of events remains a major element of reflection.

Prices in € represent the retail prices valid in Germany (unless otherwise indicated). Prices do not include postage and handling if applicable. St Martin’s church, Angers, is emblematic of the problems raised in pre-12th century history of architecture.

In view of the importance of this building, it was necessary to attempt to define its dating and this study particularly focuses on its bell-tower.

The amount of carbon dioxide in the living organism is equal to that in the atmosphere.

When the organism dies, the carbon 14 (C14) atoms disintegrate at a known rate, with a half-life of 5,700 years.

To determine the year age (absolute age) of an object, a number of chemical and radioactive techniques can be used.
