ʻO Orange Kyanite, mai Tanzania mai

wikiō

Kyanite mea he nō kāu uliuli silicate mea pōhaku, mau i loaʻa i loko o Aluminum-waiwai metamorphic pegmatites a / a sedimentary pōhaku. Kyanite ma metamorphic pōhaku nui Hōʻike malihini kiʻekiʻe ma luna o eha kilobars. 'Oiai, palena papaha ka pilina paʻa ma lalo puʻe a me ka haahaa ana wela, i ka ha awina o ka wai He IeAUPIIe, IAa IO kiʻekiʻe lawa ma lalo o ia mau rula i mea UAIAaIN e hydrous aluminosilicates e like me muscovite, pyrophyllite, a kaolinite. Kyanite ua iʻikeʻia me disthene, rhaeticite a me ka cyanite.

Kyanite He He lâlâ 'o ka aluminosilicate puke, a i ka loaʻa o ka polymorph andalusite a me ka polymorph sillimanite. Kyanite mea ikaika anisotropic, i loko o ia kona paakiki loli aʻe ke kaumaha ma muli kona crystallographic ao ao. Ma kyanite, keia anisotropism hiki ke noʻonoʻo pono i nä ano.

Ma ke anawela ma luna o 1100 ° C kyanite decomposes i mullite a vitreous ka silica i ma nā kēia naoh: 3 (Al2O3 · SiO2) → 3Al2O3 · 2SiO2 + SiO2. He loli hualoaʻa ma ka anoe.

Kona inoa hele mai, mai ka ia kumu like ia o ke ano cyan, ua loko mai o ka mea kahiko Helene hua'ōlelo κύανος. Keia ua nui ana i 'ōlelo Pelekānia i kyanos a me kuanos, a' o ia hoʻi "pouli uliuli".

Ua hoʻohanaʻiaʻo Kyanite e like me ke kaha pōhaku nui, kahi e hōʻike ai i kaʻike maka o ka cat,ʻoiai naʻe, ua palena kēia hoʻohanaʻana i kona anisotropism a me ka pipili maikaʻiʻana. ʻO nāʻano keʻano likeʻole nā ​​kyananaʻalani iʻike kokeʻia mai Tanzania mai. ʻO kaʻalaniʻalani no ka hoʻokomoʻana i nā manganese he nui (Mn3 +) i loko o ke kahua.

Kaʻike

ʻO nā kʻelina o Kyanite, nā kristal colonar he mea ia e hōʻike mua i ka mineral, a me kona laulā (i ka manawa eʻike ai ka'ōlime). ʻO nā mea i hoʻohuiʻia me nā mea'ē aʻe, ua pono pū kekahi, ma keʻano o ka hikiʻana o nā polymorphs o staurolite, e ulu pinepine me ka kyanite. Eia naʻe,ʻo ka mea kūpono loa i kaʻikeʻana i ka kianite,ʻo ia kona anisotropism. Inā manaʻo kekahi iā ia he kianite, e hōʻoiaʻiʻo ana iʻelua mauʻano paʻakikīʻano'ē aʻe ma nā aniani kikowehe he kī ia eʻike ai, he paʻakikī o 5.5 e like me [001] a me 7 e like me 100}
