Summary:

Name first used by Fuller and Clapp (1904) for coal exposed near Parkers Settlement, Posey Co., western IN. A discrepancy concerning stratigraphic position of the coal exists between Fuller and Clapp's text and columnar section, which has created some confusion in the literature. This coal is a few feet below Parker Limestone of Fuller and Clapp (Carthage Limestone Member of Bond Formation of present usage). Wier (1961, 1965, 1973) assigned Parker member rank and designated type locality in NW1/4SE1/4 sec 30, T5S, R11W, near Posey-Vanderburgh county line in Vanderburgh Co. Consists of bright-banded coal, 0.3 to 1.7 ft thick, overlain by 1 to 3 ft of black shale. Parker is thickest in Posey, Vanderburgh, and Gibson Cos., where it lies about 190 ft above West Franklin Limestone Member of Shelburn Formation. Parker is thin or absent and not generalized in western Knox Co. and western Sullivan Co. Correlates with New Haven Coal Member of Modesto Formation in IL and No. 18 coal of Sturgis Formation in northwestern KY. Age is Late Pennsylvanian (Missourian). Report includes correlation charts.
