IlliteWikipedia

Illite is a group of closely related non-expanding clay minerals. Illite is a secondary mineral precipitate, and an example of a phyllosilicate, or layered alumino-silicate. Its structure is a 2:1 sandwich of silica tetrahedron (T) – alumina octahedron (O) – silica tetrahedron (T) layers. [4]

USGS OFR01-041: Illite Group Minerals

illite group Illite is essentially a group name for non-expanding, clay-sized, dioctahedral, micaceous minerals. It is structurally similar to muscovite in that its basic unit is a layer composed of two inward-pointing silica tetragonal sheets with a central octahedral sheet.

Illite contains more water and less potassium than true micas, but it has a micalike sheet structure and is poorly crystallized.

term illite as a general term for the clay-mineral constituent of argillaceous sediments belonging to the mica group. More recently, Molloy and Kerr (1961) have described Fithian illite as Illite no. 35 in the A.P.I, project on reference clay minerals.

THE NATURE OF ILLITEThe Clay Minerals Society

Illite is dioctahedral, although some references are known which incorrectly refer to ‘illite’ as a similar alteration sequence of trioctahedral micas, although some concomitant Mg substitution in octahedral sites has been suggested.

Illite: Illite mineral information and data.

Illite – also includes glauconite (a green clay sand) and are the commonest clay minerals; formed by the decomposition of some micas and feldspars; predominant in marine clays and shales.

illitean overview | ScienceDirect Topics

Illite is a micaceous clay mineral that is a principal constituent of many argillaceous sediments (Grim et al., 1937). Illite derived from the alteration ofsmectite is considered to be the nonexpanding end-member of the illite/smectite (I/S) series of mixed-layer clays (Hower and Mowatt, 1966). .

CHEMISTRY OF ILLITE/SMECTITE AND END-MEMBER

Illite is the only clay mineral in the illite group of clay-micas. Its chemistry is complex and variable. Chemical elements in illite, including potassium, magnesium, and iron, all lower the melting temperature of a clay body containing illite.
