Clays in which soil particles tend to separate or repel each other are called dispersive clays. When clays have deflocculated in water they are called dispersed clays. "Honeycomb structure" describes an arching arrangement of soil particles somewhat resembling a honeycomb in appear ance. Particles are usually siltsized; that is, relatively loose

Industrial minerals, such as clays, sand, gravel, and crushed stone, are raw materials used for building and maintaining infrastructure, agriculture, and mitigation of environmental problems. Because of the many uses for industrial minerals in our society, land management agencies have an increasing need for better geologic and mineralogic data on industrial minerals.
