Radiocarbon dating of travertines precipitated from freshwater

Abstract

The 14C activity of recent travertines of northeastern Spain is a function of the distance from the spring, resulting in variations in the initial 14C activity of the ancient travertine formations. We calculated the ancient travertine radiocarbon ages by using the ratio between the 14C activity of recent travertines and that of present atmospheric CO2 as the initial 14C activity. -from Authors
