Clay minerals and soil interactions

The kaolins mined in Mexico resulted from the primary hydrothermal alteration of Tertiary acidic rocks (deposits at Sombrerete, Ahualulco, Huayacocotla, Pathé, Sierra de San Andrés, Nayarit, and Xilosintla) or of Triassic schists (Noche Buena). Montmorillonites are sedimentary, like the swelling type from Cuencamé, in the state of Durango, or the non-swelling type from the state of Tlaxcala. The geology of the country warrants the study of the clays associated with the Triassic (San Marcial), Jurassic (Tezoatlán-El Consuelo) and Late Cretaceous (Cohauila) coal beds, as well as with the Mesozoic sediments included in the Huayacocotla, Todos Santos, Huizachal, Las Vigas, Carbonera, Cabullona, and Guayabal formations. The Paleozoic-Tertiary intrusive rocks along the Pacific coast equally represent favorable targets for finding clay deposits.
