U-series and U-Pb carbonate geochronology

Since , scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain. New research shows, however, that some estimates based on carbon may have erred by thousands of years. It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said.

But it is already clear that the carbon method of dating will have to be recalibrated and corrected in some cases.

The general principle of isotope dating methods is based on the presence of Previous uranium-thorium (U-Th) dating of speleothems (n=from a wide.
