Illite is the dominant clay mineral of the tills. Fe-chlorite in unweathered tills alters to vermiculite or a vermiculite-montmorillonite intergrade in oxidized tills. Kaolinite is present in small amounts. The ratio of illite to kaolinite and chlorite increases in weathering profiles as chlorite alters to vermiculite. The diffraction intensity
