U-Pb Age Calculator
Introduction & Importance
U-Pb dating is a radiometric dating method that uses the decay of uranium-238 and uranium-235 to lead-206 and lead-207, respectively, to determine the age of rocks and minerals. It’s widely used in geochronology and is considered one of the most reliable methods for dating old rocks.
