Limestone in the Mississippian of Ohio, USA. (geology hammer for scale) (photo by James Cheshire) The Maxville Limestone is the only Middle to Late Mississippian-aged stratigraphic unit in Ohio. Its outcrop belt is not extensive - it principally occurs in Muskingum County and Perry County in eastern and southeastern Ohio. The Maxville Formation can also be found as cobbles and pebbles in the basal Sharon Formation (Lower Pennsylvanian), which disconformably overlies Ohio's Mississippian rocks. Paleohills, or erosional outliers, of Maxville Limestone have also been identified. Shown here are discarded limestone blocks along a quarry road in western Muskingum County, Ohio. The quarry targets Maxville Limestone and crushes it for use as road gravel, fill, rip-rap, and erosion-control blocks. The Maxville here is an erosional outlier that is described in Stout (1918). These blocks are apparently not usable by the quarries - they are yellowish-brown to orangish-brown, somewhat ferruginous limestones.
