Uyemukelwa emhlabeni othokozisayo we-prehnite! Uma uyisazi sokuma komhlaba, uzokwazi ukuthi i-prehnite iyi-calcium aluminium silicate mineral evame ukutholakala emadwaleni e-metamorphic. Kodwa kuningi kakhulu kule mineral kunalokho esikubonayo.

I-Prehnite yatholwa okokuqala ngekhulu le-18 yi-mineralogist yaseDutch, u-Hendrik von Prehn. Laqanjwa ngaye futhi livame ukubizwa ngokuthi “itshe lesiprofetho” ngoba kwakukholelwa ukuthi linezinto eziyimfihlakalo ezingasiza abantu babone ikusasa. Nakuba singeke siqinisekise lezi zimangalo, singaqinisekisa ukuthi i-prehnite iyiminerali enhle futhi ethakazelisayo inokuningi okunikezwayo emhlabeni we-geology.

Enye yezinto ezithakazelisa kakhulu nge-prehnite ukwakheka kwayo kwamakhemikhali. Yakhiwe nge-calcium, i-aluminium, ne-silicate, eyinikeza isethi eyingqayizivele yezakhiwo ezenza ibe yigugu kuma-geologists. Isibonelo, i-prehnite ivame ukusetshenziswa njenge-mineral inkomba ngoba ingasiza izazi ze-geologists ukukhomba ukuba khona kwamanye amaminerali endaweni. Lokhu kungenxa yokuthi i-prehnite ivame ukutholakala eduze kwamanye amaminerali, njenge asebenza ngebhethri, feldspar, futhi mica.

I-Prehnite nayo ibalulekile ngoba ingasiza izazi zokuma komhlaba ziqonde i-geology yendawo. Lapho i-prehnite itholakala emadwaleni e-metamorphic, ingabonisa ukuthi idwala liye lashintsha kakhulu ngenxa yokushisa nokucindezela. Lolu lwazi lubalulekile ngoba lungasiza izazi zokuma komhlaba ziqonde umlando wendawo nokuthi ishintshe kanjani ngokuhamba kwesikhathi.

Ngaphandle kokubaluleka kwayo kwesayensi, i-prehnite nayo iyiminerali enhle evame ukusetshenziselwa ubucwebe nezinto zokuhlobisa. Ngokuvamile umbala oluhlaza okotshani ophaphathekile, kodwa ungabuye utholakale emithunzini ephuzi, emhlophe, nempunga. Ukubukeka kwayo okuthambile kwenza kube ukukhetha okudumile kubaqoqi kanye nalabo abanentshisekelo kukho izibonelo zamaminerali.

Sengiphetha, i-prehnite iyiminerali ethokozisayo nebalulekile enokuningi okunikezwa izazi zokwakheka komhlaba kanye nalabo abanentshisekelo kumlando woMhlaba kanye ne-geology. Uma uyisazi sokuma komhlaba, sithemba ukuthi lo mhlahlandlela ukunikeze ukuqonda kangcono ngokubaluleka kwe-prehnite nokuthi ingasetshenziswa kanjani emsebenzini wakho.

Ukwembula i-Geology Ngemuva kweTopazi Yegolide

Posted on by i-miamimining

Golden itopazi iyitshe eliyigugu elihle elidonsa ukunaka ngemibala yalo ekhazimulayo esagolide. Kodwa ingabe wake wazibuza mayelana ne-geology ngemuva kwalesi mineral esimangalisayo? Itholakala ngokuyinhloko eBrazil, itopazi legolide iyinhlobonhlobo ye-topazi yamaminerali futhi yaziwa ngemibala yayo ephuzi kuya kowolintshi. Kulokhu okuthunyelwe kwebhulogi, sizocubungula i-geology ye-topazi yegolide futhi sithole izici zayo ezihlukile futhi ukuqeqeshwa inqubo.

Okokuqala, ake sikhulume ngemvelaphi yetopazi yegolide. Le mineral itholakala ikakhulukazi eBrazil, ikakhulukazi esifundazweni saseMinas Gerais. Imbiwa etsheni le-granitic kanye ne-gneissic, kanye ne-alluvial deposits. I-topazi yegolide ingatholakala nakwamanye amazwe, njengeRussia, Pakistan, kanye nakwamanye amazwe I-united states, kodwa amadiphozithi ase-Brazilian aziwa ngokukhiqiza amatshe ayigugu ekhwalithi ephezulu kakhulu.

Pho, yini eyenza itopazi legolide likhetheke kangaka? Kokukodwa, iyiminerali eqine kakhulu, ibekwe ku-8 esikalini se-Mohs samaminerali ubulukhuni. Lokhu kuyenza ifanelekele ukusetshenziswa kubucwebe nezinye izinto zokuhlobisa. I-topazi yegolide nayo iqinile futhi imelana nokuklwebheka nokuqoshwa, okwengeza inani layo njengetshe eliyigugu. Ngaphandle kwezakhiwo zayo ezibonakalayo, i-topazi yegolide nayo iyaziwa ngombala wayo oyingqayizivele. Ama-hues amaminerali aphuzi kuya ku-orange abangelwa ukuba khona kokungcola kwensimbi ne-chromium esakhiweni sekristalu.

Ukwakhiwa kwe-topazi yegolide kuyinkqubo eyinkimbinkimbi ehlanganisa izimo ezihlukahlukene ze-geological. Iminerali ivamise ukwakhiwa ngaphansi kwezimo ezisezingeni eliphezulu nezinengcindezi ephezulu, njengalezo ezitholakala kumatshe e-granitic kanye ne-gneissic. Ibuye itholakale kuma-alluvial deposits, okuyizindawo lapho ihanjiswe khona futhi ifakwe emanzini. Izimo ezithile ezidingekayo ekubunjweni kwetopazi legolide azikaqondwa ngokugcwele, kodwa kucatshangwa ukuthi ukuba khona kwamaminerali athile, njenge asebenza ngebhethri kanye ne-feldspar, ingase idlale indima ekubunjweni kwayo.

Ngokusetshenziswa kwayo, itopazi yegolide isetshenziswa kakhulu njengetshe eliyigugu ebucwebeni. Ibuye isetshenziswe ngezinye izikhathi ezintweni zokuhlobisa nanjengento yabaqoqi. Inani letshe eliyigugu letopazi legolide lisekelwe ezintweni ezihlukahlukene, okuhlanganisa umbala walo, ukucaca, ukusika, nesisindo se-carat. Amatshe ayigugu e-topazi egolide ayigugu kakhulu yilawo anombala ojulile, ocebile nokucaca okuhle kakhulu.

I-topazi yegolide ayiziswa nje kuphela ngenxa yezakhiwo zayo ezibonakalayo nobuhle, kodwa futhi ibamba indawo ezimweni ezihlukahlukene zamasiko nezingokomfanekiso. Kwamanye amasiko, itshe eliyigugu kukholakala ukuthi linezinto zokwelapha futhi kucatshangwa ukuthi liletha inhlanhla nokuchuma. Ibuye ngezinye izikhathi ihlotshaniswe nayo ukuthanda nobudlelwano, futhi kukholakala ukuthi buletha ukulingana nokuzwana.

Sengiphetha, itopazi yegolide iyitshe eliyigugu elithakazelisayo nelihle eline-geology eyinkimbinkimbi. Izakhiwo zayo eziyingqayizivele kanye nenqubo yokwakheka, kanye nokubaluleka kwayo kwamasiko nengokomfanekiso, kuyenza ibe amaminerali akhethekile ngempela. Noma ngabe uyisazi sokuma komhlaba, umthandi wobucwebe, or umane nje umuntu owazisa ubuhle bemvelo, itopazi legolide liyiminerali okufanele ihlolwe.
