0 a mineral in the form of crystals (= regular shapes) from which the chemical element zirconium is obtained:
Zircon has a tremendous capacity to resist breakdown during erosion, weathering, melting, and metamorphism.
Zircon is found mainly in silica-rich rocks such as granite.
The relative amounts of oxygen isotopes in the zircons points to the presence of water.
53 isotope systematics and the provenance of detrital zircons of these different terrane assemblages, as they display distinct differences.
The analysed zircons are 150-200 m in length and have only a few cracks and inclusions.
All zircons show well-developed crystal zoning; many have cracks, few have inclusions.
Alternatively, zircons from the metagranites could be inherited.
Additionally, there are three other inherited zircon populations.
