Clay minerals can be classified as 1:1 or 2:1, this originates because they are fundamentally built of tetrahedral silie sheets and octahedral hydroxide sheets, as described in the structure section below. A 1:1 clay would consist of one tetrahedral sheet and one octahedral sheet, and examples would be kaolinite and serpentine.
