Read chapter clair cameron patterson: who was working on a method for dating zircon in granitic rocks the zircon yielded nearly concordant uranium-lead. In order to do proper dating, you need to be sure that the mineral had a specific uranium content when it was formed how this particular method is done, is you take zirconium crystals, which can incorporate uranium atoms in their lattice when they grow, but will not incorporate lead thus a freshly.
