Zircon is a zirconium number 40 on the periodic table bearing silicate mineral ZrSiO4.
Decay routes[ Zircon Crystal Dating ] Uranium decays to lead via a series of alpha and Zircoh Zircon Crystal Dating, in which U and its daughter nuclides undergo a total of Zircon Crystal Dating alpha and six beta decays, whereas Ziron and its daughters only experience seven alpha and four beta decays. The term U-Pb dating normally implies the coupled use of both decay schemes in the 'concordia diagram' see below.
Since zircons have the capability to survive geologic processes like erosion, transport, even high-grade metamorphism, they are used as protolith indicators.
