Livingston Limestone Member

(CEW)

Bond Formation,

Pennsylvanian System


Type section and use of name: The name Livingston Limestone was first used by Worthen (1875, p. 11-19) for exposures near Livingston in Clark County, Ill. The type section consists of an upper limestone, 6.5 feet (2.0 m) thick a middle clay, shale, and thin coal, 4.5 feet (1.4 m) thick and a lower limestone, 14 feet (4.3 m) thick. This unit is now recognized as a member of the Bond Formation both in Illinois (Kosanke and others, 1960, p. 39, 83) and in Indiana (Wier, 1960, 1961, 1965).

Description: The Livingston Limestone Member is the upper member of the Bond Formation and is present in only two areas in Indiana. In western Sullivan County near Merom and Graysville, the unit consists of two beds of limestone separated by as much as 25 feet (7.6 m) of gray to black shale and a thin coal. The upper bed is buff to light-gray crystalline fossiliferous limestone containing abundant fenestelloid bryozoans and small brachiopods. The lower bed is dark gray, argillaceous, and nodular and contains crinoid columnals. In the Mumford Hills in northwestern Posey County and southwestern Gibson County, the Livingston Limestone Member is not conspicuously present but has been noted in drilling records as a thin limestone.

Correlation: The Livingston member in Indiana was early miscorrelated with the West Franklin Limestone Member of the Shelburn Formation (Collett, 1874; Ashley, 1899; and Shrock and Malott, 1929). This member of the Bond Formation, however, correlates with the Livingston and Millersville Limestone Members of the Bond Formation in Illinois.
