Uranium-Lead Dating

Main content Side column. Encyclopedia of Scientific Dating Methods. Uranium — Lead dating is the geological age-determination method that uses the radioactive decay of uranium U isotopes U, U, and also in this entry Th into stable isotopes of lead Pb Pb, Pb, and Pb, respectively. U—Pb geochronology is the science of both the methodology but also the application of these methods to geological problems. The accumulation of Pb in U-bearing minerals according to known decay rates of radioactive parent isotopes of U and Th forms the basis of this dating method.
