Umhlaba Othakazelisayo We-Prehnite: Umhlahlandlela Wezazi Zomhlaba
uJan
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.
