Ukuthola Ubuhle Obukhangayo Bamakristalu Omgogodla: Ukubheka Okujulile Kwezimo Zabo Ze-Geological
Dec
Amakristalu omgogodla awuhlobo lwamaminerali aziwa ngobuhle bawo obumangalisayo kanye nezinhlobonhlobo zemibala. Lawa makristalu angatholakala emithunzini ebomvu, ebomvana, ensomi, eluhlaza okwesibhakabhaka, eluhlaza, namnyama, futhi aziswa ngesakhiwo sawo esiyingqayizivele sekristalu nokubukeka okukhazimulayo. Kulokhu okuthunyelwe kwebhulogi, sizobheka ngokujulile izici ze-geological zamakristalu e-spinel, sihlola imvelaphi yawo, ukuqeqeshwa, kanye nezinto ezibonakalayo.
Amakristalu omgogodla ayingxenye yeqembu le-spinel lamaminerali, elihlanganisa izinhlobonhlobo ze-silicates ne-chemical formula MgAl2O4. Lawa maminerali aziwa kakhulu ukumelana nokushisa nokuguga, futhi avame ukusetshenziswa njengama-abrasives namatshe ayigugu. Amakristalu omgogodla avame ukutholakala emadwaleni e-metamorphic, njengemabula ne-serpentinite, futhi angatholakala nasemadwaleni e-metamorphosed ultramafic kanye nama-mafic igneous rocks.
Ukwakhiwa kwamakristalu e-spinel kuyinqubo eyinkimbinkimbi ehilela ukuguqulwa kwamaminerali akhona ngaphansi kwezingcindezi eziphezulu namazinga okushisa. Le nqubo, eyaziwa ngokuthi i-metamorphism, ingenzeka ngaphakathi koqweqwe lomhlaba or i-mantle, futhi ngokuvamile ihlotshaniswa nomsebenzi we-tectonic kanye nokungena kwe-magma. Njengomphumela we-metamorphism, amakristalu e-spinel angase akhe njengama-inclusions ngaphakathi kwamanye amaminerali, noma angase acwebe ngokuzimela njengamakristalu ahlukene.
Ngokuphathelene nezakhiwo zomzimba, amakristalu e-spinel ayaziwa ngokudonsela phansi kwawo okuphezulu, ubulukhuni, kanye nenkomba ye-refractive. Lezi zakhiwo, kuhlanganiswe nemibala yazo egqamile nokubukeka okukhazimulayo, kwenza amakristalu e-spinel abaluleke kakhulu njengamatshe ayigugu. Eqinisweni, amakristalu e-spinel asetshenziswe njengamatshe ayigugu amakhulu eminyaka, futhi aye aziswa ngabasebukhosini nabaqoqi ngokufanayo. Amanye amakristalu omgogodla adume kakhulu emhlabeni ahlanganisa “i-Black Prince’s Ruby,” umgogodla omkhulu, obomvu obekwe ku-Imperial State Crown of England, kanye ne-“Timur Ruby,” umgogodla omkhulu, ophinki oyingxenye ye ama-Crown Jewels aseBrithani.
Sengiphetha, amakristalu e-spinel awuhlobo oluhehayo lwamaminerali aziwa ngobuhle bawo obuhehayo kanye nezici eziyingqayizivele ze-geological. Kusukela ezinhlobonhlobo zazo zemibala kuya ezintweni zazo ezibonakalayo, lawa makristalu adonse ukunaka kwezazi zokwakheka komhlaba kanye nabathandi bamatshe ayigugu ngokufanayo. Kungakhathaliseki ukuthi uyisazi sokuma komhlaba noma umane nje unokwazisa ngamagugu omhlaba, amakristalu e-spinel ngokuqinisekile azovusa uzungu futhi ajabule.
