I-Orange kyanite, evela eTanzania

ividiyo

Kyanite kuyinto ngokuvamile blue silicate amaminerali, ngokuvamile atholakala aluminium-ocebile pegmatites metamorphic kanye / noma sedimentary idwala. Kyanite kwamadwala metamorphic ngokuvamile ibonisa izingcindezi ephakeme kunaleyo kilobars ezine. Nakuba engase esigculisayo umfutho ongaphansi kanye lokushisa eliphansi, umsebenzi amanzi ngokuvamile okusezingeni eliphezulu ngokwanele ngaphansi kwezimo ezinjalo ukuthi esikhundleni aluminosilicates hydrous ezifana muscovite, pyrophyllite, noma kaolinite. Kyanite yaziwa nangokuthi disthene, rhaeticite futhi cyanite.

Kyanite eyilungu uchungechunge aluminosilicate, okuyinto sihlanganisa lo andalusite polymorph kanye sillimanite polymorph. Kyanite asivumelani ngokuqinile anisotropic, e okwenza ubulukhuni bayo iyahlukahluka kuye ngokuthi isiqondiso salo crystallographic. Ngo kyanite, lokhu anisotropism angabhekwa isici lokuhlonza.

Emazingeni ngenhla 1100 ° C kyanite ubola ku mullite futhi Silica Vitreous nge eyasabela ngayo: 3 (Al2O3 · SiO2) → 3Al2O3 · 2SiO2 + SiO2. Lokhu ukuguqulwa kuphumela ukunwetshwa.

igama Its livela umsuka efanayo ukuthi we ikhayeni umbala, kokuba ethathwe oMdala lesiGreki elithi κύανος. Lokhu ngokuvamile ihunyushelwa esiNgisini njengoba kyanos noma kuanos futhi lisho "blue amnyama".

I-Kyanite isetshenzisiwe njengegugu elincane, elingase libonise inkulumo yekati, nakuba lokhu kusetshenziswe kunqunywe yi-anisotropism yayo nokucaca okuphelele. Izinhlobonhlobo zembala zifaka nje u-orange kyanite osanda kutholakala eTanzania. Umbala we-orange ubangelwa ukufakwa kwamanani amancane we-manganese (Mn3 +) esakhiweni.

Ubunikazi

Ama-kyanite ahlanganisiwe, amakhemikhali e-columnar ngokuvamile ayibonakaliso yokuqala ye-mineral, kanye nombala wawo (uma ucwecwe luhlaza okwesibhakabhaka). Amaminerali ahlanganisiwe ayasiza futhi, ikakhulukazi ukuba khona kwama-polymorphs e-staurolite, okwenzeka njalo nge-kyanite. Kodwa-ke, isici esiwusizo kakhulu ekuboneni i-kyanite yi-anisotropism yayo. Uma umuntu osolwa ukuthi i-kyanite, ukuqinisekisa ukuthi kunobunzima obubili obuhlukile ngokuhlukile kwezingxenyana zokukhomba, kuyinkinga ye-5.5 ehambisana ne {001} no-7 parallel ku {100}
