Raw zvinhu zvepamusoro siliceous ivhu zvinokanganisa zvidhinha

Huru mbichana zvigadzirwa zvevhu rakakwira silika ivhu rinokanganisa zvidhinha ivhu (rakaumbwa rakaoma ivhu, kaolin kana pyrophyllite uye yakasikwa quartz jecha. Zvinoenderana nemhando dzakasiyana dzezvigadzirwa, yakakwira silika yevhu zvidhinha zvinogona kukamurwa kuita quartz-kaolinite yakakwirira Kune marudzi maviri yesilina zvidhinha uye quartz-ivhu rakakwira-silika yevhu zvidhinha.
