Formation of clay minerals by hydrothermal action and their mineralogical properties have been reviewed with some discussions on the relations of hydrothermal alteration to weathering and diagenesis, on the chemical compositions of dioctahedral 2 : 1 clay minerals and chlorite minerals, and on the polytypes of some sericite minerals. There are wide variations in the parent materials, the water resources, the alteration conditions and processes of the hydrothermal alterations, and almost all kinds of clay minerals with moderate crystallinity are found in the alteration envelopes in Japan. Hydrothermal dioctahedral mica minerals known as sericite are characterized by their mineralogical properties intermediate between muscovite and illite. It is noticed that the typical fine-grained clay minerals in the dioctahedral 2 : 1 type and chlorite minerals (sericite, illite, glauconite, montrnorillonite, leptochlorite, sudoite, and donbassite) show nonintegral but approximately fixed populations of interlayer cations.
