Clay minerals are stacked, polymeric sandwiches of tetrahedral and octahedral sheet structures (3, 9–12).They are classified first into “layer types,” differentiated by the number of tetrahedral and octahedral sheets that have combined, and then into “groups,” differentiated by the kinds of isomorphic cation substitution that have occurred ().
