Clay minerals also play important roles in biogeochemical cycling and interact with the environment to affect geomorphic processes such as weathering, erosion and deposition. This data provides new spatially explicit clay mineralogy information for Australia that will help to improve our understanding of soils and their role in the functioning of landscapes and ecosystems....Chat Now
Illite Howling Pixel
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.

THE CLAY MINERAL GROUP Amethyst Galleries
The mineral illite is the only common mineral represented, however it is a significant rock forming mineral being a main component of shales and other argillaceous rocks. The general formula is (K, H)Al2(Si, Al)4O10(OH)2 xH2O, where x represents the variable amount of water that this group could contain.
Clay mineral Chemical and physical properties: Depending on deficiency in the positive or negative charge balance (locally or overall) of mineral structures, clay minerals are able to adsorb certain cations and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic silicate structure....Chat Now

1:1 Clay Minerals The 1:1 layer minerals contain one tetrahedral and one octahedral sheet in their basic structural unit (Fig. 2.) This two-sheet mineral type is represented by the kaolin group, with the general formula Al2Si205(0H)4. Kaolinite, the most common mineral in this group, is dioctahedral, exhibiting Al3+ octahedral and Si4+ tetrahedral coordi-
Clay minerals are an important group of minerals because they are among the most common products of chemical weathering, and thus are the main constituents of the fine-grained sedimentary rocks called mudrocks (including mudstones, claystones, and shales). In fact clay minerals make up about 40% of the minerals in sedimentary rocks....Chat Now
Illite and hydrocarbon exploration | PNAS
Illite is a general term for the dioctahedral mica-like clay mineral common in sedimentary rocks, especially shales. Illite is of interest to the petroleum industry because it can provide a K-Ar isotope date that constrains the timing of basin heating events. It is critical to establish that hydrocarbon formation and migration occurred after the formation of the trap (anticline, etc.) that is
ILLITE GROUP. 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). Formation of illite is generally favored by alkaline conditions and by high concentrations...Chat Now
Kaolinite: The clay mineral kaolinite information and pictures
Kaolinite is a clay mineral, with a soft consistency and earthy texture. It is easily broken and can be molded or shaped, especially when wet. Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorphs, especially after feldspars.
Clay minerals include the following groups: Chlorite group includes a wide variety of similar minerals with considerable chemical variation. Clay minerals are characterized by two-dimensional sheets of corner sharing SiO 4 and AlO 4 tetrahedra. These tetrahedral sheets have ...Chat Now

Jul 16, 2010· Ferric illite (sometimes misleadingly called non-marine glauconite) most often forms green illite-rich claystones rather than granules. The iron content is much less, and the aluminium content higher than in marine glauconitic minerals. It forms in palaeosols and hypersaline lacustrine environments, and is not known from marine environments....Chat Now

Illite: Illite mineral information and data. Mindat
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.

"Identifying clay minerals for their diffraction tracing is something of a Gestalt process, i.e., identifying the whole being able to say that it is an illite/smectite because it has an illite/smectite pattern." (Moore and Reynolds 1997:296) In other words, you just have

Illite Mineral: Structure and Formation | Soil Minerals
The chemical formula of illite is (K,H 3 O)(Al, Mg, Fe) 2 (Si,Al) 4 O 10 [(OH) 2,(H 2 O)] and its molecular weight is 389.34 g. It is usually gray-white to silvery-white, or greenish-gray in color. The specific gravity of the mineral varies from 2.6 to 2.9. Illite is also called clay mica or hydrous mica or hydrous muscovite.
Illite is similar to muscovite and is the most common clay mineral, often composing more than 50 percent of the clay-mineral suite in the deep sea. They are characteristic of weathering in temperate climates or in high altitudes in the tropics, and typically reach the ocean via rivers and wind transport....Chat Now

Clay mineral Chemical and physical properties
Although kaolinite, illite, chlorite, and smectite are the principal clay mineral components of deep-sea sediments, their compositions vary from place to place. 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.
