Phakathi kwezinhlayiya zamaminerali ezakha i-granite, ezingaphezu kuka-90% yi-feldspar ne-quartz, okuyi-feldspar eningi kakhulu. I-feldspar ivame ukuba mhlophe, mpunga, futhi ibomvu njengenyama, kanti i-quartz iningi layo ayinambala noma imhlophe ngwevu, okwenza umbala oyisisekelo we-granite. I-Feldspar ne-quartz zingamaminerali aqinile, futhi kunzima ukuzihambisa ngommese wensimbi. Ngokuphathelene namabala amnyama ku-granite, ikakhulukazi i-mica emnyama, kunezinye izimbiwa. Nakuba i-biotite ithambile, ikhono layo lokumelana nokucindezeleka alibuthakathaka, futhi ngesikhathi esifanayo banenani elincane ku-granite, ngokuvamile lingaphansi kuka-10%. Lesi yisimo sezinto lapho i-granite inamandla khona kakhulu.
Esinye isizathu esenza i-granite ibe namandla ukuthi izinhlayiya zayo zamaminerali zinamathelene futhi zinamathele komunye nomunye. Izikhala zivame ukuba ngaphansi kuka-1% womthamo ophelele wedwala. Lokhu kunikeza i-granite ikhono lokubekezelela ukucindezeleka okunamandla futhi ayingeni kalula umswakama.
