Illite Clay Mineral

Clay minerals - Wikipedia

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.

CHEMISTRY OF ILLITE/SMECTITE AND END-MEMBER ILLITE

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).

Smectite Group: Mineral information, data and localities.

Prior to circa 1975, the smectite group was called the montmorillonite-saponite group. Smectite minerals have large specific surface areas (10 - 700 m2/g) and exhibit a high expansion (swelling) capability in the presence of H2O. Smectite and vermiculite minerals are often referred to as "swelling" or "expandable" clay minerals.
