Maxville Limestone; Rushville, Logan, and Cuyhoga Formations, Undivided (OHMlc;0)

Maxville Limestone; Rushville, Logan, and Cuyhoga Formations, Undivided

Shale, siltstone, and sandstone, interbedded; various shades of gray, yellow to brown weather similar color; sandstone, silty to granular, local stringers of quartz pebbles. Shale, clayey to silty, locally fossiliferous. Medium to dark gray, thin to thick bedded limestone locally preserved at top of interval where unit crops out in southern half of state. Lithologies percentages vary in different areas where unit crops out; laterial and vertical gradation common at regional scale.
