Importance of zircon in uranium-lead dating - Britannica
Dating - Importance of zircon in uranium-lead dating: The mineral zircon adds three more fundamental advantages to uranium–lead dating First, its crystal structure allows a small amount of tetravalent uranium to substitute for zirconium but excludes with great efficiency the incorporation of lead (It might be said that one begins with an empty box)
Zircon (/ ˈ z ɜːr k ɒ n / or / ˈ z ɜːr k ən /) is a mineral belonging to the group of nesosilicat Its chemical name is zirconium silicate, and its corresponding chemical formula is Zr SiO 4 A common empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x (OH) 4x–y
Zircon is a natural product and as such slight variations in the chemical analysis and size distribution should be expected Special contracts covering guarantees other than those specified may be negotiated ** Values calculated based on concentrations of other elements *** Typical values based on historical production performance
