fluor

fluor

A relative dating method based on the fact that bones buried in the ground progressively lose nitrogen and gain fluorine and other trace elements. The rate at which these changes occur depends on the local environment. If two bones from the same site have markedly different amounts of nitrogen and fluorine, it is a strong indication that they did not come from the same time period. The bone with the least amount of nitrogen and the greatest amount of fluorine is most likely the oldest.
