Dating methods stone tools
The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.
Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope C.
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.
b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.
It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.
The most common relative dating method is stratigraphy.
Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata.
This principle presumes that the oldest layer of a stratigraphic sequence will be on the bottom and the most recent, or youngest, will be on the top.
The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.
