Calgary live web cameras - Stratigraphic dating
For those researchers working in the field of human history, the chronology of events remains a major element of reflection.
Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.
This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.
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.
These methods usually analyze physicochemical transformation phenomena whose rate are known or can be estimated relatively well.
This is the only type of techniques that can help clarifying the actual age of an object.
