The Age of the Earth - Lead Isotopes as a Current Scientific Clock: Paul Bechard

Lead isotopes are commonly used in dating rocks and provide some of the best evidence for the Earth's age. In order to be used as a natural clock to calculate the age of the earth, the processes generating lead isotopes must meet the four conditions of a natural clock: an irreversible process, a uniform rate, an initial condition, and a final condition.
