Description

The Bogota-Rinard Syncline initially was recognized from subsurface mapping of the Pennsylvanian Herrin Coal Member in Jasper, Richland, and Wayne Counties. Subsequent mapping shows that the syncline is present in deeper strata, including the Mississippian Karnak Limestone Member (Bristol and Howard 1976), Devonian New Albany Shale (Stevenson et al. 1981), and Ordovician Galena Group (Bristol and Buschbach 1973). These authors' maps show the syncline following a sinuous course southward from northern Coles County to central or southern Wayne County. The syncline is bordered on the east by the Charleston Monocline (new) and Clay City Anticline (new name). The trough or axis of the Fairfield Basin partially coincides with the Bogota-Rinard Syncline.
