Pennsylvanian System

Type section and use of name: The Riverview Limestone Member was named by Wier (1961, 1965) for exposures of a thin limestone at the northeast edge of Riverview, Sullivan County, Ind., in the SW¼SW¼SE¼ sec. 24, T. 9 N., R. 11 W., and was assigned to the Bond Formation.

Description: The Riverview Limestone Member is one bed, 0.3 to 0.8 foot (0.1 to 0.2 m) thick, of medium- to dark-gray argillaceous gastropod-rich limestone. It lies about 40 feet (12 m) above the Fairbanks Coal Member in the type area and is directly underlain by black shale and an unnamed thin discontinuous coalbed. The limestone is best exposed in the type area and near New Harmony in northwestern Posey County.
