This is termed the lead—lead dating method. Uranium—lead datingabbreviated U—Pb datingis one of the oldest  and most refined of the radiometric dating schemes. The Wikibook Historical Geology has a page on the topic of: Thus the current ratio of lead to uranium in the mineral can be used to determine its age [ citation needed ]. Although zircon ZrSiO 4 is most commonly used, other minerals such as monazite see: Chronostratigraphy Geochronology Isotope geochemistry Law of superposition Luminescence dating Samarium—neodymium dating.

Where crystals such as zircon with uranium and thorium inclusions do not occur, a better, more inclusive, model of the data must be applied. This page was last edited on 29 Januaryat These fission tracks inevitably act as conduits deep within the crystal, thereby providing a method of transport to facilitate the leaching of lead isotopes from the zircon crystal. Chinese Japanese Korean Vietnamese. Clair Cameron Pattersonan American geochemist who pioneered studies of uranium—lead radiometric dating methods, is famous for having used it to obtain one of the earliest estimates of the age of the Earth.
