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.

I-Pyrite, eyaziwa nangokuthi igolide lesiwula, iyiminerali ye-sulfide evamile etholakala ezindaweni ezihlukahlukene ze-geological. Inombala ohlukile wethusi-ophuzi kanye nokucwebezela kwensimbi, okuholele esiteketisoni sayo. Nakuba ingase ifane negolide esweni elingaqeqeshiwe, i-pyrite empeleni ihluke kakhulu ngokwezakhiwo zayo ezingokomzimba namakhemikhali.

I-pyrite inesakhiwo se-cubic crystal, ne-molecule ngayinye eyakhiwe ama-athomu ensimbi nesibabule ahlelwe ngendlela ethile. Ngokuvamile kutholakala ngesimo samakristalu amancane, akheke kahle, nakuba kungenzeka futhi njengama-aggregates amakhulu, ama-granular.

I-Pyrite itholakala ezindaweni eziningi ezihlukene ze-geological, okuhlanganisa amatshe e-sedimentary, amadwala e-metamorphic, kanye ne-hydrothermal deposits. Ivame ukuhlotshaniswa namanye amaminerali afana asebenza ngebhethri, i-calcite, ne-galena.

Esinye sezici ezihluke kakhulu ze-pyrite ubulukhuni bayo. Esikalini se-Mohs, esisetshenziselwa ukukala ubulukhuni bamaminerali, i-pyrite iwela ku-6.5, ethambile kancane kune-quartz kodwa eqine kakhulu kune-talc. Lokhu kwenza kube lula ukuklwebha ngommese or enye into ebukhali, kodwa kunzima ukuyichoboza noma ukuyihlikihla.

Ngokwendawo, i-pyrite ingatholakala emhlabeni wonke, nakuba ivame kakhulu ezindaweni ezithile. Ivamise ukutholakala kumadiphozithi amakhulu ezindaweni ezifana neNingizimu Melika, iSpain, neChina. Kwe I-united states, ivame ukutholakala eziNtabeni Zase-Appalachian nasezifundeni ezisentshonalanga, ikakhulukazi e- Nevada futhi Colorado.

Enye yezinto ezibaluleke kakhulu ukusetshenziswa kwe-pyrite njengensimbi yensimbi. Insimbi iyisici esibalulekile ekukhiqizeni insimbi, futhi i-pyrite iwumthombo obalulekile wale nsimbi. Ngaphezu kokusetshenziswa kwayo embonini yensimbi, i-pyrite iphinde isetshenziswe njengomthombo wesulfure futhi njenge-catalyst embonini yamakhemikhali.

I-Pyrite nayo ingumdlali obalulekile ku- ukuqeqeshwa we-acid mine drainage, okuyinkinga enkulu yezemvelo ezindaweni eziningi zomhlaba. Lapho i-pyrite ivezwa emoyeni nasemanzini, isabela ukuze yenze i-sulfuric acid, engakhipha izinsimbi ezisindayo nobunye ubuthi edwaleni nasenhlabathini ezungezile. Lokhu kungangcolisa amanzi futhi kudale umonakalo omkhulu endaweni.

Naphezu kwemithelela yayo engemihle kwezemvelo, i-pyrite isalokhu iyimineral ebalulekile embonini yokwakheka komhlaba nezimayini. Izakhiwo zayo eziyingqayizivele kanye nokwenzeka kwayo okusabalele kuyenza ibe umthombo obalulekile okungenzeka uzoqhubeka nokuxhashazwa iminyaka eminingi ezayo.

Ihlosi elibomvu liyi-mineral ephawulekayo elaziswa ngemibala yalo eyingqayizivele namaphethini. Ivame ukusetshenziselwa ubucwebe nezinye izinto zokuhlobisa ngenxa yobuhle bayo bemvelo nokuqina. Kodwa kuthiwani ngeso lehlosi elibomvu elenza likhetheke kangaka?

Red tiger iso izinhlobonhlobo asebenza ngebhethri, i-mineral evamile etholakala ezinhlotsheni eziningi zamatshe. Ivamise ukwakhiwa ngaphakathi kwamadwala e-metamorphic, okungamatshe aguqulwe ukushisa nokucindezela. Uma i-quartz ingaphansi kwalezi zimo, ingathatha izakhiwo nemibala emisha, okuholela kumaminerali afana ne-red tiger eye.

Ihlo lehlosi elibomvu lithola umbala walo ohlukile ku-iron oxide, ekhona kumaminerali ngamanani amancane. Lapho i-iron oxide ichayeka ekukhanyeni, ibuyisela emuva amaza abomvu, okwenza iso lengwe elibomvu libe nombala walo obomvu. Umbala wehlo lehlosi elibomvu ungasuka kobomvana ophaphathekile uye kobomvu ngokujulile, kuye ngenani le-iron oxide elikhona.

Ngaphezu kombala walo, iso lengwe elibomvu liyaziwa ngokuxoxa, or ikhono lokubonisa ukukhanya ebhandeni elincane. Lokhu kunikeza i-mineral umphumela “weso lekati”, yingakho ngokuvamile ibizwa ngokuthi iso lengwe. I-chatoyancy yehlo lehlosi elibomvu ibangelwa ukuhlelwa kwemicu ngaphakathi kweminerali, ebonisa ukukhanya ngendlela ethile.

Ihlo lehlosi elibomvu linemisebenzi eminingi engokoqobo ngaphezu kwenani lalo lokuhlobisa. Kuyiminerali eqinile uma kuqhathaniswa, okwenza ifanelekele ukusetshenziswa ebucwebeni nakwezinye izinto ezingase ziguge. Ihlo lehlosi elibomvu kukholakala ukuthi linezinto zokuphulukisa futhi livame ukusetshenziswa emithini yendabuko kanye nemikhuba yomoya.

Sengiphetha, iso lengwe elibomvu liyiminerali ethakazelisayo elaziswa ngombala walo oyingqayizivele namaphethini. Yakho ukuqeqeshwa ngaphakathi kwamadwala e-metamorphic kanye nokuba khona kwe-iron oxide kuyinikeza isici sayo sombala obomvu nokuxoxa. Kungakhathaliseki ukuthi ungumthandi wokwakheka komhlaba noma umane ujabulela ubuhle bamaminerali, iso lengwe elibomvu liyiminerali ekhangayo futhi ehlukahlukene okufanele ihlolwe.
