and vermiculite layers). The most abundant species are illite (30-50%) and chlorite (10-20%). Typical vermiculite occurs through-out in variable proportions (5-30%) mixtures of chlorite and chlorite-smectite and the expandable phase is primarily vermiculite however it is a significant rock forming mineral being a main component of shales and other argillaceous rocks. The general formula is (K,
