Absolute and relative dating in archaeology

During and after an excavation, an archaeologist confronts a bewildering collection of artifacts, drawings, and photographs to decipher and relate to one another.Using both relative and absolute dating methods, an archaeologist can often place a site within a larger chronological framework.

Relative dating of a site's stratigraphy often depends on the absolute dating of excavated materials and artifacts.The requirement of identical burial conditions means that fluoride dating works best when it is applied within a single site with little variation in soil chemistry.Many different techniques can be used to measure bone fluoride content, but measurement by ion selective electrode is the easiest and simplest method available today.Over time, buried bones pick up fluoride ions from soil moisture or exposure to groundwater.Older specimens have higher fluoride contents than younger ones when burial conditions are identical.

Dating inorganic materials is also quite challenging, because relatively few artifacts come labeled with a date of manufacture.
