The Silurian McKenzie Formation is a mapped bedrock unit in Maryland.[2]
Description[]
The McKenzie Formation is a gray, thin-bedded shale and argillaceous limestone, with interbedded red sandstone and shale in its eastern extents in Maryland. The thickness ranges from 160 to 380 feet.[2] It houses shallow water fauna including but not limited to brachiopods, Ostracods, and tentaculitids.
Age[]
Relative age dating of the Tuscarora places it in the Silurian period. It rests conformably atop the Clinton Group and conformably below the Bloomsburg Formation.[2]
