Ukusetshenziswa Kwamaminerali Ngokusekelwe Kokuqukethwe Kwendawo
Amaminerali ayimithombo yemvelo eyakhiwa ngezinqubo ze-geological eminyakeni eyizigidi. Ukusatshalaliswa kwawo akufani, kodwa kuncike ezimweni zezwe kanye nomlando wokwakheka kwamadwala esifundeni. Ngakho-ke, ukusetshenziswa kwamaminerali kuncike kakhulu "kokuqukethwe kwendawo" kwendawo—okungukuthi, uhlobo lwedwala, isakhiwo se-tectonic, umsebenzi wentaba-mlilo, isimo sezulu, kanye nezinqubo zesimo sezulu ezakha futhi zigxilise amaminerali athile. Ukuqonda ubudlelwano phakathi kwendawo kanye nokuqukethwe kwamaminerali kubalulekile ekuhleleni intuthuko esimeme, ukuthuthukiswa kwezimboni, ukuphathwa kwamandla, kanye nokuphathwa kwemvelo.
1. Kungani Okuqukethwe Kwamaminerali Kuthinteka Yindawo?
Ngokwejiyoloji, amaminerali ngokuvamile akhiwa ngezindlela eziningana eziyinhloko: i-magma crystallization, i-metamorphism ngenxa yokucindezela okuphezulu kanye nokushisa, imvula evela ezixazululweni ze-hydrothermal, kanye ne-sedimentation ebusweni boMhlaba. Ngayinye yalezi zindlela ihlobene eduze nendawo kanye nezici zendawo yendawo. Izindawo ezisemaphethelweni ezintaba-mlilo zivame ukuceba ngamaminerali athile ensimbi (njengegolide nethusi), kuyilapho izitsha ze-sedimentary zinamandla amakhulu okukhiqiza amalahle, uphethiloli, noma amaminerali ezimboni njenge-gypsum ne-limestone. Izindawo ezisogwini kanye nolwandle olungajulile zingase zibe nesihlabathi samaminerali (njenge-ilmenite ne-rutile) noma usawoti.
Ngakho-ke, ukusetshenziswa kahle kwezimbiwa kumele kucabangele amamephu e-geological, ukusatshalaliswa kwezindawo ezigciniwe, ukufinyeleleka kwesifunda, kanye nemiphumela yezemvelo neyezenhlalo.
2. Amabhande Entaba-mlilo: Imithombo Yezinsimbi Ezinenani Eliphezulu
Izindawo ezitholakala ezindaweni zezintaba-mlilo—uchungechunge lwezintaba-mlilo ezisebenzayo nezasendulo—zivame ukusebenza njengezindawo ezishisayo zamaminerali ensimbi. Izinqubo ze-magmatic kanye ne-hydrothermal zingaletha izixazululo ezicebile ngensimbi ezibe sezibangela ukuqhekeka kwamadwala. Umphumela uba ama-deposit amaminerali anenani eliphezulu kwezomnotho.
Izibonelo zamaminerali avame ukutholakala ezindaweni zezintaba-mlilo:
