The Kerbel Formation is a geologic formation in Ohio. It dates back to the Cambrian. Named by Adriaan Janssens[1] in the 1973.[2]
The Kerbel Formation's thickness is about 50 meters. Is consists if sandstones changing from fine-grained at the bottom to coarse-grained at the top. These sandstones were previously assigned to the Dresbach Formation or Franconia Formation and found in multiple locations between eastern Wisconsin and northwestern Ohio / south-eastern Michigan (through northeastern Illinois and northern Indiana).[3]
The Kerbel Formation is correlated to the Galesville Formation and Ironton Formation of Illinois and is equivalent to Eau Claire Formation in western Ohio (and Conasauga Formation in eastern Ohio). John Rodgers included the sandstones into Conasauga Group in the 1953. The eastern Kentucky sandstones correlated to Kerbel Formation were also described as part of Knox Group. In eastern Ohio the Kerbel Formation turns dolomitic and thins out into Knox Dolomite.[3]
