An accessory rock in igneous and metamorphic rocks.
Περιγραφή:
Zircon, zirconium orthosilicate, is found in most igneous rocks and some metamorphic rocks as small crystals or grains, mostly widely distributed and rarely more than 1% of the total mass of the rock. It is also found as alluvial grains in some sedimentary rocks due to its high hardness. Zircon has a high index of refraction and, where crystals are large enough, is often used as a gemstone.
