Phakathi kweengqungquthela zamaminerali ezenza i-granite, ngaphezu kwe-90% yi-feldspar kunye ne-quartz, apho i-feldspar ininzi. I-feldspar ihlala imhlophe, ingwevu, kunye nenyama-bomvu, kwaye i-quartz ininzi ayinambala okanye i-grayish emhlophe, eyenza umbala osisiseko wegranite. I-Feldspar kunye ne-quartz ziiminerali ezinzima, kwaye kunzima ukuhamba ngemela yentsimbi. Ngokuphathelele amabala amnyama kwigranite, ikakhulu i-mica emnyama, kukho ezinye iiminerali. Nangona i-biotite ithambile, ukukwazi ukumelana noxinzelelo akunamandla, kwaye kwangaxeshanye banexabiso elincinci kwi-granite, kaninzi ngaphantsi kwe-10%. Le yimeko yezinto eziphathekayo apho i-granite yomelele ngakumbi.
Esinye isizathu sokuba i-granite yomelele kukuba iinqununu zayo zamaminerali zibophe ngokuqinileyo komnye nomnye kwaye zifakwe omnye komnye. Imingxuma idla ngokuba ngaphantsi kwe 1% yomthamo opheleleyo wamatye. Oku kunika i-granite amandla okumelana noxinzelelo olunamandla kwaye ayingenwa lula ngokufuma.
