Among the most useful chronometric dating techniques are radiocarbon dating, potassium argon dating, and thermoluminescence dating.
Dendrochronology, the relationship of dated ancient trees with live trees has no CATEGORY: technique DEFINITION: The use of various methods, often multiple methods, to demonstrate the equivalency of stratigraphic units.
Fluorine dating: Bones from fossils absorb fluorine from the groundwater.
The amount of fluorine absorbed indicates how long the fossil has been buried in the sediments.➤ It determines the age of a rock/object using radiometric techniques.➤ Absolute dating is quantitative.➤ This technique helps determine the exact age of the remains.➤ It is more specific than relative dating.➤ Absolute dating is expensive and time-consuming.➤ It works best for igneous and metamorphic rocks.
Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations.
These remains are subjected to dating techniques in order to predict their ages and trace their history.
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.
, in which figures in solar years (often with some necessary margin of error) can be applied to a particular event.
Unless tied to historical records, dating by archaeological methods can only be relative -- such as stratigraphy, typology, , fluorine and nitrogen test, and radiometric assay.
Absolute dating, also called numerical dating, arranges the historical remains in order of their ages.
Whereas, relative dating arranges them in the geological order of their formation.
