Illite is the only common mineral. Chlorite group includes a wide variety of similar minerals with considerable chemical variation.

  • Illite Wikipedia

    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.

  • Kaolinite an overview ScienceDirect Topics

    Various mica-vermiculites and illite-vermiculite are common in podzols, while chlorite-vermiculite is found in a wide range of soil types on chlorite-bearing rock. Kaolinite-smectite (or more probably the kaolin mineral is halloysite, though this has only recently been recognized) is particularly abundant in soils formed on basic igneous rock.

  • Chlorite an overview ScienceDirect Topics

    This clay is probably more abundant than either illite or smectite. Interstratified chlorite-smectite is associated with alteration of basic igneous rock or rock fragments in sandstone. Regularly interstratified chlorite-smectite and chlorite-vermiculite with 50% of each component are both known as corrensite. 14 Å chlorite interstratified with 7 Å chlorite is becoming a more widely

Weathering of large phyllosilicates pre-existing in the saprolite involves physical fragmentation and mineralogical transformations.

    Commonly described mixed-layer clays include: illite-vermiculite, illite-smectite, chlorite-vermiculite (corrensite), chlorite-smectite, and kaolinite-smectite. Mixed-layer clays can form by weathering involving the removal or uptake of cations (e.g. K), hydrothermal alteration, or removal of hydroxide interlayers, and, in some cases, may represent an intermediate stage in the formation of

    Illite, vermiculite, smectite, chlorite, and interstratified clay minerals are found in podzolic soils. Sepiolite and palygorskite have been reported in some aridisols (desert soils), and kaolinite is the dominant component in oxisols (lateritic soils). Clay minerals other than those mentioned above usually occur in various soils as minor components inherited from the parent materials of those
