Lead-lead dating is a method used in geochronology to determine the age of geological materials, particularly rocks and minerals. This technique involves analyzing the ratios of lead isotopes, specifically lead-206 (Pb-206) and lead-207 (Pb-207), which are the end products of the radioactive decay of uranium isotopes (U-238 and U-235, respectively).
