Yiziphi izinto zomhlaba ezingavamile
Context:Amaminerali omhlaba angavamile aqukethe into eyodwa noma eziningi zomhlaba ezingavamile njengezakhi ezinkulu zensimbi. Amaminerali omhlaba angavamile avame ukutholakala ngokuhlangana nama-alkaline kuya kuma-peralkaline igneous complexes, kuma-pegmatites ahlobene nama-alkaline magmas kanye noma ahlobene ne-carbonatite intrusives. Izigaba zamaminerali e-perovskite ziyizindawo ezivamile zezakhi zomhlaba ezingavamile ngaphakathi kwezakhi ze-alkaline. Ama-carbonate ancibilikile atholakala ku-mantle nawo athwala izinto zomhlaba ezingavamile. Imithombo eshisayo ehambisana ne-alkaline magmatism iqukethe amaminerali ahlukahlukene angavamile.
Nakuba ekuqaleni kwakucatshangwa ukuthi ayivelakancane, amaminerali amaningi empeleni ajwayelekile emkhakheni womhlaba. Nokho, ngenxa yobunzima bokukhipha insimbi emgodini, igama elithi ezingavamile lifaneleka.
