Relative and chronometric dating
Among the most useful chronometric dating techniques are radiocarbon dating, potassium argon dating, and thermoluminescence dating.
SYNONYMS OR RELATED TERMS: chronology CATEGORY: technique DEFINITION: The process by which an archaeologist determines dates for objects, deposits, buildings, etc., in an attempt to situate a given phenomenon in time.Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.There are two main categories of dating methods in archaeology: indirect or relative dating and absolute dating.Idea that something is older or younger relative to something else Expressed in terms of order.Assignment of an age to a physical remain based on the association with other remains of known age.This term refers to the relation of one stratigraphical unit to another, by petrological, osteological, lithographic, cultural, chronological, or palaeontological means.
For example, stratigraphic units may be correlated using palaeontological criteria, methods, and position relative to the glacial-interglacial cycle by examining physical and biological attributes.
No wonder, then, that so much effort has been devoted to developing increasingly sophisticated and precise methods for determining when events happened in the past.
In archaeology, dating techniques fall into two broad categories: chronometric (sometimes called “absolute”) and relative.
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.
