  • Montmorillonite Wikipedia

    Montmorillonite is a very soft phyllosilicate group of minerals that form when they precipitate from water solution as microscopic crystals, known as is named after Montmorillon in , a member of the smectite group, is a 2:1 clay, meaning that it has two tetrahedral sheets of silica sandwiching a central octahedral sheet of alumina.

  • Clay minerals Wikipedia

    Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them.

  • Soil Management

    As clay minerals are intensely weathered, the structure of silicates clays change. Particularly, the silicate clays lose silica. What remains in the soil are aluminum and iron oxides. Gibbsite is an example of an aluminum oxide, which has a grayish, whitish hue. Goethite is an example of an iron oxide, which imparts a reddish color to the soil.
