Water is essential for clay mineral formation and most clay minerals are defined as hydrous alumino silicates. They form in soils and sediments, and by diagenetic and hydrothermal alteration of rocks. Clay mineralogy is the science dealing with the structure of clay minerals on microscopic, molecular, and atomic scale. any of a group of minerals consisting of hydrated aluminium silicates: the major constituents of clays. Clay is a type of fine-grained natural soil material containing clay minerals. The mineralogy can be broadly subdivided into the clay and non-clay minerals, including poorly crystalline, so-called ‘amorphous’ inorganic phases.
