Illite Mineral: Structure and Formation Soil Minerals

Web9 mei 2024 · The process of illitization (smectite is transformed to illite) is a major change that takes place in mudstones during the diagenesis. Illitization consumes potassium (provided usually by detrital K- feldspar) and liberates iron, magnesium and calcium, which can be used by the other forming minerals like chlorite and calcite.
