Clay mineral Clay mineral Origin: All the clay minerals, with the possible exception of halloysite, have been synthesized from mixtures of oxides or hydroxides and water at moderately low temperatures and pressures. Kaolinite tends to form in alumina-silica systems without alkalies or alkaline earths. Illite is formed when potassium is added to such systems.
