Introduction to Clay Minerals Soils

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.
