Uranium-lead: Long-lived radioactive isotopes of uranium (235U and 238U) decay to stable lead (207Pb and 206Pb, respectively) at a rate, which is constant but different for the two systems. The ratio of accumulated lead to remaining uranium is a function of time and is a direct measure of the time of formation of minerals and rocks.
Zircon: A mineral consisting principally of zirconium, silicon, and oxygen and with trace amounts of uranium.
