Kyanite munhu yemanyorero mutema silicate chicherwa, anowanzonzi kuwanikwa aruminiyamu-vapfumi metamorphic pegmatites uye / kana sedimentary dombo. Kyanite mu metamorphic matombo kazhinji rinoratidza nematambudziko kupfuura kilobars mana. Kunyange anogona kugadzikana panguva yakaderera kumanikidzwa netembiricha pasi, basa mvura kazhinji yakakwirira zvakakwana mumamiriro ezvinhu akadaro kuti kuchatsiviwa hydrous aluminosilicates akadai muscovite, pyrophyllite, kana kaolinite. Kyanite inonziwo disthene, rhaeticite uye cyanite.

Kyanite ndiyo nhengo aluminosilicate series, iyo inosanganisira polymorph andalusite uye polymorph sillimanite. Kyanite ndiye zvakasimba anisotropic, pakuti ayo pokuoma dzinosiyana-siyana zvichienderana ayo crystallographic mirayiridzo. In kyanite, anisotropism ichi inogona kunzi kuonekwa noruzhinji.

At kutonhora pamusoro 1100 ° C kyanite uchiora kupinda mullite uye vitreous silica nomukombiyuta zvinotevera zvakaitwa: 3 (Al2O3 · SiO2) → 3Al2O3 · 2SiO2 + SiO2. kuchinja Izvi zvinoguma imwe kuwedzera.

zita raro rinobva chete kwakabva kwakaita ruvara cyan, kuitwa zvinobva Ancient rechiGiriki κύανος. Izvi kazhinji kushandurwa Chirungu sezvo kyanos kana kuanos uye rinoreva "mutema rima".

Kyanite yakashandiswa sechinhu chisingatauriki, iyo inogona kuratidzira maziso echechi, kunyange kushandiswa uku kunogadziriswa neanisotropism uye kukwana kwakakwana. Mhando dzakasiyana-siyana dzinosanganisira munguva ichangobva kuwanikwa orange kyanite inobva kuTanzania. Mucheka wemaruva unokonzerwa nekuiswa kwemazana emanganese (Mn3 +) muchimiro.

Chiratidzo

Kyanite yakarongedzwa, makristori emakona anowanzova chiratidzo chekutanga chemaminerari, uyewo maruva ayo (apo mufananidzo wacho uri bhuruu). Kusanganiswa nemaminerari kunobatsirawo zvakare, kunyanya kuvapo kwema polymorphs e staurolite, anowanzoitika kyaniti. Zvisinei, chinhu chinonyanya kukosha pakuziva kyanite ndechekuti anisotropism. Kana munhu akangokonzera shanduro kuva kyanite, achivimbisa kuti ine zvakaoma zvakasiyana zvakasiyana zvakasiyana pazvirevo zvakasiyana-siyana ndeyekukosha kwekutaura, ine utera hwe 5.5 parallel na {001} uye 7 parallel na {100}
