  • 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.
