Summary:

Named North Bend Tongue of Fairview Formation. Composed of interbedded shale and fossiliferous limestone in which no stratum is persistently thicker than 1.5 ft and generally not more than 0.6 ft. 12 ft thick at type section. Forms tongue of Fairview Formation extending north and west from the Cincinnati, OH, area. Underlain by Kope Formation; overlain by Wesselman Tongue of Kope Formation.

Summary:

The Kope-Fairview-Bellevue succession is the first of three major progradational units that compose the Cincinnatian Series in the Cincinnati, OH, area. Each succession is interpreted as a mixed siliciclastic-carbonate ramp. The Kope Formation is the most distal facies of the ramp complex. The Fairview Formation is the intermediate-depth lithofacies in the upward-shoaling succession. The North Bend Tongue, at the base in southwestern OH, is separated from the main body of the Fairview by the Wesselman Tongue of the Kope. The North Bend becomes indistinguishable 15 to 20 km northwest of Cincinnati. Age shown as Late Ordovician (Maysvillian).
