Industrial resources (minerals) are geological materials that are mined for their commercial value, which are not fuel (fuel minerals or mineral fuels) and are not sources of metals (metallic minerals) but are used in the industries based on their physical and/or chemical properties. [1]
Several different types of bentonite can be found; however, potassium bentonite is the main one associated with the Deicke and Millbrig eruptions. The Deicke and Millbrig K-bentonite layers can be found from Alabama to New York to Minnesota. These K-bentonite layers are up to a meter thick in some locations. [8] Such thickness is unique.
