Zircon ( / ˈzɜːrkɒn, - kən /) [ 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 ...
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.

Titanium in zircon geothermometry is a form of a geothermometry technique by which the crystallization temperature of a zircon crystal can be estimated by the amount of titanium atoms which can only be found in the crystal lattice. In zircon crystals, titanium is commonly incorporated, replacing similarly charged zirconium and silicon atoms.
