lead is extracted from uranium to create lead ore. A system might go through a geological process that removes lead, leaving the resultant system devoid of uranium.
Rocks are frequently dated using lead isotopes, which offer some of the best proof of the Earth's age. The activities producing lead isotopes must satisfy all four requirements of a natural clock—an irreversible process, a uniform rate, a starting condition, and a final condition—in order to be utilised as a natural clock to determine the age of the world. This approach ultimately influenced the creation of isochrons, which plot two isotopes against one another to determine the age of the mineral or rock.
Scientists can establish how long the parent isotope has existed by comparing the relative levels of the two isotopes and understanding the rate of decay.
