Phakathi kwee-minerali ezincinci ezenza i-granite, ngaphezulu kwe-90% yi-feldspar kunye ne-quartz, apho i-feldspar yeyona ininzi. I-feldspar idla ngokuba mhlophe, ngwevu, kwaye ibomvu njengenyama, kwaye i-quartz ikakhulu ayinambala okanye imhlophe ngwevu, nto leyo eyenza umbala osisiseko we-granite. I-Feldspar kunye ne-quartz ziiminerali eziqinileyo, kwaye kunzima ukuzihambisa ngemela yentsimbi. Ngokuphathelele amabala amnyama kwi-granite, ikakhulu i-mica emnyama, kukho ezinye iiminerali. Nangona i-biotite ithambile, amandla ayo okumelana noxinzelelo abuthathaka, kwaye kwangaxeshanye ine-granite encinci, edla ngokuba ngaphantsi kwe-10%. Le yimeko yezinto ezibonakalayo apho i-granite inamandla ngakumbi.
Esinye isizathu sokuba igranite ibe namandla kukuba amasuntswana ayo eeminerali anamathelene ngokuqinileyo kwaye anamathele omnye komnye. Iimbobo zihlala zingaphantsi kwe-1% yomthamo uwonke welitye. Oku kunika igranite amandla okumelana noxinzelelo olunamandla kwaye ayingeni lula kumswakama.
