Kyanit se yon mineral silikate tipikman ble, souvan yo te jwenn nan aliminyòm ki rich pègmatit metamòfik ak / oswa wòch sedimantè. Kyanit nan wòch metamòfik jeneralman endike presyon pi wo pase kat kilobars. Malgre ke potansyèlman ki estab nan pi ba presyon ak tanperati ki ba, aktivite a nan dlo se nòmalman wo ase anba kondisyon sa yo ke li se ranplase pa aluminozilikat idrolojik tankou moskovit, pirofilit, oswa kaolinit. se kyanit ke yo rele tou disthene, rhaeticite ak cyanite.

Kyanite is a typically blue silicate mineral, commonly found in aluminium-rich metamorphic pegmatites and/or sedimentary rock. Kyanite in metamorphic rocks generally indicates pressures higher than four kilobars. Although potentially stable at lower pressure and low temperature, the activity of water is usually high enough under such conditions that it is replaced by hydrous aluminosilicates such as muscovite, pyrophyllite, or kaolinite. Kyanite is also known as disthene, rhaeticite and cyanite.
