Kyanite ke ka tloaelo ho putsoa metaborate matsoai, ka tloaelo fumanoe ka pegmatites aluminium ho rua metamorphic le / kapa sedimentary rock. Kyanite ka majoe metamorphic kakaretso bontša likhatello phahame ho feta kilobars bane. Leha nang tsitsitseng ka khatello ea tlaase le mocheso tlaase, mosebetsi oa metsi hangata e phahameng ka ho lekaneng tlas'a maemo a joalo hore e nkeloa sebaka ke aluminosilicates hydrous kang muscovite, pyrophyllite, kapa kaolinite. Kyanite e tsejoang hape e le disthene, rhaeticite le cyanite.

Kyanite e leng setho sa letoto la lihlooho tse aluminosilicate, eo e boetse e akarelletsa ho polymorph andalusite le polymorph sillimanite. Kyanite ke matla anisotropic, ka hore ebe thatafala lona fapana ho itšetlehile ka tataiso ea lona crystallographic. Ka kyanite, anisotropism ena ka nkoa e le tšobotsi khethollang.

Ha thempereichara e ka holimo 1100 ° C kyanite bola ka mullite le silica vitreous ka tsela ba itšoara joang latelang: 3 (Al2O3 · SiO2) → 3Al2O3 · 2SiO2 + SiO2. ntlafalo Sena se fella ka katoloso ya ya.

Lebitso la eona le tsoa hlahang ho yona e tšoanang e le hore ba 'mala cyan, ba nkiloeng ho tloha ea boholo-holo Segerike lentsoe κύανος. Sena e ka kakaretso le fetoletsoeng e le ka Senyesemane e le kyanos kapa kuanos le bolela "lefifi putsoa".

Kyanite e 'nile ea sebelisoa e le lejoe la majoe, le leng le ka bonts'a moqoqo oa leihlo la ketsahalo, le hoja tšebeliso ena e lekanyelitsoe ke anisotropism ea eona le cleavage e phethahetseng. Mefuta e mengata ea mebala e kenyelletsa morao tjena o fumane kyanite ea Orange e tsoang Tanzania. Mmala a lamunu a bakoa ke ho kenngoa ka manganese a mangata (Mn3 +) mohahong oo.

Boitsebiso

Kyanite e khabisitsoeng ka kakaretso, ka kristale e khantšang ka letsoho hangata e le pontšo ea pele ea diminerale, hammoho le 'mala oa eona (ha setšoantšo se le letsoa). Meriana e kopantsoeng e boetse e na le thuso, haholo-holo boteng ba polymorphe ea staurolite, e hlahang hangata le kyanite. Leha ho le joalo, tšobotsi ea bohlokoa ka ho fetisisa ho khetholla kyanite ke anisotropism ea eona. Haeba motho a belaella mohlala oa hore e be kyanite, ho netefatsa hore o na le mathata a mabeli a fapaneng a fapaneng ka likhahla tse fapaneng ke senotlolo sa ho khetholla, o na le bothata ba 5.5 parallel ho {001} le 7 parallel ho {100}
