Phakathi kwamasuntswana amaxinaphu ezenza i-granite, ngaphezulu kwe-90% yi-feldspar kunye ne-bidz, yeyona feldspaar kakhulu. I-feldspaar ihlala imhlophe, i-grey, kunye nenyama ebomvu, kwaye i-quartz ingenamibala okanye i-greysh imhlophe, eyenza umbala osisiseko wegranite. I-feldspaar kunye ne-quartz ziiminerals ezinzima, kwaye kunzima ukuhamba nenyoka yentsimbi. Ngokuphathelele amabala amnyama kwiGranite, ubukhulu becala mica emnyama, kukho ezinye iiminerali. Nangona i-biotite ithambile, amandla ayo okuxhathisa uxinzelelo ayibuthathaka, kwaye kwangaxeshanye banayo imali encinci eGranite, rhoqo ngaphantsi kwe-10%. Le yimeko ye-subnite apho igranti inamandla ngakumbi.
Esinye isizathu sokuba igrayite yomelele kukuba amasuntswana awo angqinwa ngokuqinileyo omnye komnye kwaye axhonywe omnye komnye. Iipores zihlala zichaza ngaphantsi kwe-1% yegama elipheleleyo lelitye. Oku kunika igrafite ukuba ikwazi ukumelana neengcinezelo ezomeleleyo kwaye ayifakwanga lula ukufuma.
