Uranium Series Dating . SpringerLink

Prof Z - Uranium Thorium

Chronometric Dating in Archaeology pp Cite as. Uranium decays through a number of radioactive daughter isotopes, some of which have half-lives comparable to the time scale of prehistoric archaeology. The growth of these isotopes in naturally occurring materials at archaeological sites can be used to determine the age of sites. The growth of Th from its parent, U, can be used over a time range from a few hundred to half a million years. Bones, teeth, mollusk and egg shells, are also datable but present problems due to migration of parent U in and out of the samples during their burial history. Unable to display preview.

The decay of Uranium to Thorium is part of the much longer decay series begining in U and ending in Pb. With time, Thorium accumulates in the sample through radiometric decay. The method assumes that the sample does not exchange Th or U with the environment i. The method is used for samples that can retain Uranium and Thorium, such as carbonate sediments, bones and teeth.
