Ibukeka kanjani i-quartz (isithombe)

I-quartz isakazeke kakhulu emhlabeni; amatshe amaningi okuhlobisa ayigugu futhi okuhlobisa ayingxenye yawo. Ngaphezu kwalokho, kubhekwa njenge-rock-forming, okungukuthi, ifakwe njengezingxenye ezibalulekile ezihlala njalo ekubunjweni kwamadwala.

Izici ezibonakalayo eziyinhloko

Ngendlela yayo ehlanzekile, i-mineral isobala ngokuphelele futhi ayinawo umthunzi. Ngezinye izikhathi kungenziwa ngopende omhlophe ngenxa yokuba khona kwemifantu yangaphakathi kanye namaphutha ekristalu. Ukukhanya kwekristalu kucacile, kune-vitreous, ngezinye izikhathi kunamafutha kunqwaba eqinile. Kwenzeka ngendlela yobuningi obuyimbudumbudu obuqhubekayo bombala omhlophe oyi-milky noma ingase yakhe izinhlamvu ezihlukene emadwaleni.

Uma ukwakheka kwegugu kuhlanganisa izakhi ezihlukahlukene-ukungcola noma i-microparticles yamanye amaminerali (ikakhulukazi i-iron oxide), khona-ke lokhu kunikeza umthunzi othile, ongahluka ngokuphelele. Kodwa-ke, ayisabhekwa njenge-quartz ehlanzekile - amatshe anjalo anamagama awo ahlukene futhi angawezinhlobonhlobo zaleli qembu. Isibonelo, i-morion emnyama, i-lemon citrine, i-prasiolite eluhlaza okwesibhakabhaka, i-rauchtopaz ebhemayo, i-aventurine eluhlaza okotshani, i-amethiste ensomi, i-onyx ensundu nabanye. Izizathu zomthunzi wezinhlobonhlobo ezahlukene zinemvelo yazo ekhethekile.

Zonke izinhlobo zinezici zomzimba ezicishe zifane. I-vitreous luster efanayo, ubulukhuni obuphezulu, izimo ezifanayo zokubunjwa kanye nokuba sengozini kuma-acids nokushisa.
