Groundwater age dating methods used in archaeology
Radiocarbon dating is a method that provides objective age estimates for carbonbased materials that originated from living organisms an age could be estimated by measuring the amount of carbon14 present in the sample and comparing this against an internationally used reference standard.
dating principles of isotopic dating all absolute isotopic ages are based on radioactive decay a process whereby a specific atom or isotope is converted into another specific atom or isotope at a constant and known rate most elements exist in different atomic forms that are identical in their chemical properties but differ in the number of.
geochronology nonradiometric dating in addition to radioactive decay many other processes have been investigated for their potential usefulness in absolute dating unfortunately they all occur at rates that lack the universal consistency of radioactive decay sometimes human observation can be maintained long enough to measure.
