Book excerpt: Excerpt from Stratigraphic and Mineralogic Relations and Ceramic Properties of Clay Deposits of Eocene Age in the Jackson Purchase Region, Kentucky and in Adjacent Parts of Tennessee Clay deposits in the Jackson Purchase region, Kentucky, and in adjacent parts of Tennessee, in the northeastern part of the Mississippi embayment, are the major domestic source of ball clay. The deposits are widely spaced lenses in the Wilcox, Claiborne, and Jackson Formations of Eocene age. All deposits mined, except one in the Wilcox, are in the Claiborne. X-ray analyses of clay from deposits in each of the three formations show that clay-mineral composition varies according to stratigraphic position. The clay deposits in all formations are chiefly kaolinite, but montmorillonite, illite, and mixed-layer clay are present. Kaolinite is considerably more abundant in the Wilcox and Claiborne Formations; it averages 70 percent of the total clay in 16 samples analyzed. Montmorillonite, which rarely exceeds 5 percent in Wilcox and Claiborne clay deposits, generally makes up a large part, 14 to 50 percent, in most samples from clay deposits in the Jackson Formation. Clay that contains more than 10 percent montmorillonite is unsuited for most ceramic purposes. Thus, X-ray data indicate that the Claiborne and Wilcox Formations have greater potential as sources of ceramic-grade clay than has the Jackson Formation. Most commercial clay deposits in Kentucky are in lenses in strata indicated by pollen to be of middle and late Claiborne age. The pollen types and lithologic relations suggest that these clay lenses were deposited in two ancient valleys.
