    Clays form flat hexagonal sheets similar to the micas. Clay minerals are common weathering products (including weathering of feldspar) and low-temperature hydrothermal alteration products. Clay minerals are very common in soils, in fine-grained sedimentary rocks such as shale, mudstone, and siltstone and in fine-grained metamorphic slate and phyllite. Clay minerals are usually (but not necessarily) ultrafine-grained (normally considered to be less than 2

  • Clay Minerals Clays and Minerals

    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.

    DescriptionRelation to MiningUsesEven though no standard definition of the term “clay” is accepted by geologists, agronomists, engineers, and others, the term is generally well understood by those who use it. Clay is an abundant, naturally occurring, fine-grained material composed predominantly of hydrous aluminum silicates.Clay is not a single mineral, but a number of minerals. Clays fall into six general categories: kaolin, ball clays, fire clays, bentonite, common clays and Fuller’s earth. Clays are common all over the wo...

  • Clay mineral Origin Britannica

    Clay mineral Clay mineral Origin: All the clay minerals, with the possible exception of halloysite, have been synthesized from mixtures of oxides or hydroxides and water at moderately low temperatures and pressures. Kaolinite tends to form in alumina-silica systems without alkalies or alkaline earths. Illite is formed when potassium is added to such systems.

    Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usually white, mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar.

    Clay minerals have a wide range of particle sizes from 10's of angstroms to millimeters. (An angstrom is a unit of measure at the scale of atoms.) Thus, clays may be composed of mixtures of finer grained clay minerals and clay-sized crystals of other minerals such as quartz, carbonate, and metal oxides. Clays and clay minerals are found mainly

    The effect of a clay mineral filler on CTE can be quite pronounced. A clay mineral has a much higher modulus than the matrix and thus highly resists matrix deformation. Moreover, the platy clay mineral particles can resist in two directions, and are thus better than fibres. For dimensional stability, a clay mineral effect may thus be assumed.

    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.
