Zircon (/ ˈ z ɜːr k ɒ n,-k ən /) [7] [8] [9] is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium. Its chemical name is zirconium(IV) silicate, and its corresponding chemical formula is Zr SiO 4. An empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x ...
World production trend of zirconium mineral concentrates. Zirconium has a concentration of about 130 mg/kg within the Earth's crust and about 0.026 μg/L in sea water. It is the 18th most abundant element in the crust. [18] It is not found in nature as a native metal, reflecting its intrinsic

Hadean zircon is the oldest-surviving crustal material from the Earth's earliest geological time period, the Hadean eon, about 4 billion years ago. Zircon is a mineral that is commonly used for radiometric dating because it is highly resistant to chemical changes and appears in the form of small crystals or grains in most igneous and metamorphic host rocks.
