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.For more information on stratigraphy and how it is used in archaeology, see the Stratigraphy glossary entry.Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object.
Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.
Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time.
Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history.
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.
