Phakathi kwezinhlayiya zamaminerali ezakha i-granite, ngaphezu kwama-90% yi-feldspar kanye ne-quartz, okwakukhona kakhulu. I-FeldSpar ivame ukuba mhlophe, mpunga, futhi ibomvu yenyama, futhi i-quartz ingenamibala noma i-greyw white, eyakha umbala oyisisekelo wegranite. I-FeldSPar ne-Quartz amaminerali anzima, futhi kunzima ukuhamba ngommese wensimbi. Ngokuqondene namabala amnyama eGranite, ikakhulukazi i-MICA emnyama, kukhona amanye amaminerali. Yize i-biotite ithambile, amandla ayo okumelana nengcindezi ayibuthakathaka, futhi ngasikhathi sinye banemali encane eGranite, imvamisa ngaphansi kuka-10%. Lesi yisimo esibonakalayo lapho i-granite inamandla khona ikakhulukazi.
Esinye isizathu esenza ukuthi i-granite iqinile ukuthi izinhlayiya zayo zamaminerali ziboshwe ngokuqinile komunye nomunye futhi zifakwe komunye nomunye. Ama-pores avame ukulandisa okungaphansi kwe-1% yevolumu ephelele yedwala. Lokhu kunikeza ama-granite amandla okumelana nezingcindezi eziqinile futhi awengeniswa kalula ngumswakama.
