Pakati pezvinhu zvicherwa zvinoumba granite, zvinopfuura 90% i feldspar ne quartz, izvo feldspar ndiyo yakawanda. Feldspar inowanzova chena, grey, uye tsvuku-nyama, uye quartz inonyanya kuva chena isina ruvara kana grey, iyo inoumba ruvara rwegranite. Feldspar ne quartz zvicherwa zvakaoma, uye zvakaoma kufambisa nebanga resimbi. Kana dziri nzvimbo dzakasviba dziri mugranite, kunyanya mica nhema, kune zvimwe zvicherwa. Kunyangwe biotite yakapfava, kugona kwayo kuramba kushushikana hakuna kusimba, uye panguva imwe chete ine huwandu hushoma mugranite, kazhinji isingasviki 10%. Iyi ndiyo mamiriro ezvinhu umo granite yakasimba zvikuru.
Chimwe chikonzero chinoita kuti granite ive yakasimba ndechekuti zvicherwa zvayo zvakabatana zvakasimba uye zvinopindana. Maburi anowanzoita pasi pe1% yehuwandu hwese hwedombo. Izvi zvinoita kuti granite ikwanise kumira kumanikidzwa kwakasimba uye haipindike nyore nyore neunyoro.
