Illite: Mineral information, data and localities.

The literature on "illite" is among the largest in all of mineralogy as it is a widespread component of sediments. Schultz (1978) studied the the development of samples that were 20-60% illite that was randomly interstratified with varying smectite layers (i.e. beidellite or montmorillonite).

USGS OFR01-041: Illite Group Minerals

Illites, which are the dominant clay minerals in argillaceous rocks, form by the weathering of silicates (primarily feldspar), through the alteration of other clay minerals, and during the degradation of muscovite (Deer and others, 1975).

Illite an overview ScienceDirect Topics

2010-7-16  Grim et al. (1937) developed the term illite to describe clay-size mica that was found in argillaceous rocks. Other terms that have been used in lieu of illite are hydromica, hydromuscovite, hydrous illite, hydrous mica, K-mica, micaceous clay, and sericite. Illite has more Si 4+, Mg 2+, and H 2 O but less tetrahedral Al 3+ and K + and water than muscovite.

The clay mineral content of the bulk materials ranged from 40 to 80% with kaolinite ranging from ∼30 to 80% and illite from ∼3 to 30% . There was no discrete smectite in the ball clays, although ethylene glycol solvation sometimes caused a slight shift in the profile of the 10 Å illite reflection, suggesting a small amount of expandable interlayers.

USGS OFR01-041: Illite Group Minerals

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. However, illite has on average slightly more Si, Mg, Fe, and water and slightly

Clay Chemistry Bentonite, Illite, Montmorillonite

Although Illite is an aluminum silicate, it is a non-swelling clay. Illite has the same range of use as the smectite clays. In fact, some believe that Illite performs better than the smectite clays when used internally, the consideration being that the particle size of illite is smaller than smectite particles.

Rock-physics modeling of shale during smectite-to-illite

2016-10-12  Modeling the smectite mineral properties is significant due to the feature of dehydration. Because changes of bulk volume, density and modulus from K-feldspar to quartz is smaller than those changes from smectite to illite and water, we presume that smectite mineral can be seen as composed of illite sheet and soft interlayer or bound water.
