, 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.

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 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.

For periods or areas for which no textual evidence is available, relative chronologies have to be established and these are mostly based on pottery sequences and typology.

Relative chronology is also based on the application of the principles of stratigraphy and .

The amount of thermoluminescence from a heated sample is used to determine the number of trapped electrons resulting from the absorption of alpha radiation.

The quantity of light emitted will depend on three factors -- the number of flaws in the crystal, the strength of the radioactivity to which it has been exposed, and the duration of exposure.

Most of these techniques produce results with a techniques do not.For example, a lithium fluoride crystal can preferentially respond to gamma thermal neutron, beta proton, or alpha particle radiation depending on whether it is constructed from The constancy of the RDR is even more problematic because it’s based on the uniformitarian assumption that the RDR has been constant.
