Uranium-series dating of speleothems.
Abstract
Uranium and thorium geochemistry is described in application to U-series dating of speleothems by the 230Th/234U, 231Pb/235U, and 234U/238U methods. The principles and limitations of each dating method are discussed, followed by a description of the analytical techniques used in obtaining sources for alpha spectrometry. Previous results on speleothem dating are summarized. Age data for 125 speleothems from several limestone regions in North …
