The ores in the manganese deposits of the Batesville district are classified into 4 major types: manganiferous limestone, residual in situ clay, clay-talus residuum, and placer. Manganiferous limestone, mostly in the Early Mississippian St. Joe and Boone Formations, is the most abundant ore; but is usually low grade.
