I-Orange kyanite, evela eTanzania

yokuzonwabisa

Kyanite i silicate ngezimbiwa ngokuqhelekileyo blue, ngokuqhelekileyo zifumaneka pegmatites nentlenga aluminiyam-abazizityebi kunye / okanye ludaka rock. Kyanite ematyeni nentlenga ibonisa ngokubanzi iingcinezelo ngaphezulu kilobars ezine. Nangona ezinokuba izinzile kwi umfutho kunye kubushushu obuphantsi, umsebenzi amanzi idla eliphezulu ngokwaneleyo phantsi ezinjalo kweemeko indawo yayo ithathwe aluminosilicates hydrous ezifana muscovite, pyrophyllite, okanye kaolinite. Kyanite yaziwa ngokuba disthene, rhaeticite kunye cyanite.

Kyanite lilungu thotho aluminosilicate, nayo leyo kubandakanya andalusite polymorph kunye sillimanite polymorph. Kyanite na anisotropic kakhulu, ukuba lukhuni yayo kuyahlukana nedlela kwawo crystallographic. Xa kyanite, le anisotropism kunokuthathwa luphawu olubonakalisa.

Kwiqondo lobushushu ngaphezu 1100 ° C kyanite abole abe mullite kunye dust vitreous nge abasabela ilandelayo: 3 (Al2O3 · SiO2) → 3Al2O3 · 2SiO2 + SiO2. Le ukuguqulwa aphumela kwi ukwanda.

Igama layo livela ngemvelaphi efanayo naleyo umbala oluhlaza, ukuba zivela uMdala lesiGrike κύανος igama. Oku jikelele iguqulelwe IsiNgesi njengoko kyanos okanye kuanos kwaye lithetha "blue emnyama".

I-Kyanite isetyenziswe njengesigxina esinqabileyo, esinokubonisa ukukhanya kwamehlo enkatha, nangona le ndlela isetyenzisiwe yi-anisotropism yayo kunye nokucoca okugqibeleleyo. Iintlobo zembala zibandakanya i-orange kyanite esanda kuvela eTanzania. Umbala we-orange ufune ukufakwa kwamanani amancinci ama-manganese (Mn3 +) kwisakhiwo.

Uchonga

I-kyanite i-eliteated, i-crystalal columnar yinto ebonakalayo yinto yokuqala yokubonisa imaminerali kunye nombala wayo (xa i-specimen ibhakabhaka). Iimaminerali ezidibeneyo zincedo ngokunjalo, ngokukodwa ubukho beepolymorphs ze staurolite, ezenzeka rhoqo ngekyanite. Nangona kunjalo, uphawu olubalulekileyo kakhulu ekuboneni i-kyanite yi-anisotropism yayo. Ukuba umntu uphonsela i-specimen ukuba yi-kyanite, eqinisekisa ukuba unobunzima obunzima obuhlukileyo ngokucacileyo kwi-axptocular axis isitshixo ekubonakalisweni, inobunzima be5.5 efana ne {001} kunye ne-7 efana ne {100}
