  • Detrital zircon geochronology Wikipedia

    Detrital zircon geochronology is the science of analyzing the age of zircons deposited within a specific sedimentary unit by examining their inherent radioisotopes, most commonly the uranium–lead ratio. The chemical name of zircon is zirconium silie and its corresponding chemical formula is Zr SiO 4.

  • Zircon Dating ScienceAid

    Zircon is commonly found as the primary mineral in igneous rocks. Since igneous rocks have no fossils, this makes zircon valuable in dating them. Zircon also concentrates Uranium (You) and (although less so) Thorium (Th) and excludes lead (Pb), which means it has a very high You/Pb ratio.
