Jul 16, 2010 · As a consequence of diagenetic replacement by illite, smectite is virtually unknown from pre-Mesozoic sediments, while throughout the Mesozoic and Early Tertiary, smectite is the principal clay mineral found in sediments of most types. Glauconite is most abundant at the end of the Cambrian and the end of the Cretaceous, while .
Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earth's surface. They are found most often in shales, the most common type of sedimentary rock. In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil.

Structure of Illite mica - USGS. Illite is a non-expanding clay crystalline mineral. Illite is a secondary mineral precipitate phyllosilicate or layered alumino-silicate. Its structure is a 2:1 clay of silica tetrahedron – alumina octahedron – silica tetrahedron layers. The space between individual clay crystals is occupied by poorly hydrated potassium .
Illite is an extremely weathered clay, and is classified as a mica. This clay can be used on its own, or mixed with other clays for great skin care formulas, or for internal supplementation. It mixes readily with equal parts water and clay.
Illite, most commonly known as French green clay, is a type of mineral clay valued for its highly absorbent properties. Illite is a bio-mineral, composed of both decomposed plant material and trace minerals such as calcium, aluminum, magnesium, silica, phosphorous, copper and zinc.

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). .
The clay mineral type and composition varied between the clay particle size classes due to their origin and the transformations that occurred, particularly for illite and vermiculate through K + release and adsorption in the interlayers. In this study, the following soil processes that modify the soil mineralogy were identified.

Over 4,714 mineral species descriptions are included in this HTML-linked alphabetical listing of all known valid mineral species.
Illite is a general term for the dioctahedral mica-like clay mineral common in sedimentary rocks, especially shales (1, 2). Although it has a strict mineralogical definition (3), the name
Definition: Clay minerals are the characteristic minerals of the earths near surface environments. They form in soils and sediments, and by diagenetic and hydrothermal alteration of rocks. Water is essential for clay mineral formation and most clay minerals are described as hydrous alumino silicates.
Illite is a non-expanding, clay-sized, micaceous mineral. Illite is a phyllosilicate or layered alumino-silicate. Its structure is constituted by the repetition of Tetrahedron – Octahedron – Tetrahedron (TOT) layer.

34 THIRTEENTH NATIONAL CONFERENCE ON CLAYS AND CLAY MINERALS The present paper presents analytical data for several clay-mineral assemblages ranging from illite without any mixed layering to illite-mixed-
Weathering & Clay Minerals: Geologists recognize two categories of weathering processes . If you can feel it expand as it becomes moistened, then it is one of the smectite clays, and is not a kandite or illite clay. X-ray techniques, are thus usually required to identify the clay minerals. First, however, the clays have to be separated .
In general, illite is the dominant clay mineral in the North Atlantic Ocean (greater than 50 percent), while smectite is the major component in the South Pacific and Indian oceans. In some limited regions, these compositions are significantly altered by other factors such as airborne effects, in which sediments are transported by winds and .
Illite definition, any of a group of clay minerals, hydrous potassium aluminosilicates, characterized by a three-layer micalike structure and a gray, light green, or yellowish-brown color. See more.
Illite definition is - any of a group of clay minerals having essentially the crystal structure of muscovite. any of a group of clay minerals having essentially the crystal structure of muscovite. See the full definition
The most prevalent Estonian clay minerals are: illite, illite-smectite, kaolinite, and chlorite. Mooste Manor--a gem among Estonian manors driving preservation of the architectural style Illite content decreases, while chlorite content increases with depth, contributing over 30% of the clay fraction.
Sacred Clay typically possesses component clay minerals of all major classifications of clay – the Smectite Group, the Kaolinite Group, the Illite Group, and the Chlorite Group. Montmorillonite and Pyrophyllite belong to the Smectite Group, although Pyrophyllite is at times given its own clay category (Pyrophyllite/Talc) due to its simplistic .

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. 
Illite – The term illite is used in two ways: in the general sense Grim et al (1937) introduced it as the 3-layer (Figure 4) muscovite-like monoclinic or rhombohedral mineral in the clay size fraction, but which has less K and more water than muscovite and gives a 10 Angstrom d(001) from X-ray diffraction: (K,H 3 O)Al 2 (Si 3 Al)O 10 (H 2 0 .
Another clay with known healing power is Illite, a clay mica: Potassium aluminum silicate hydroxide fluoride. The chemistry of this type of healing clay reveals many similarities to the smectites, although the two clays are truly strikingly different:
