Distribution Comments:
Tuscumbia Chert is associated with the Tuscumbia Limestone Formation.  This formation is commonly included in the overlying Fort Payne Formation.  Tuscumbia Chert occurs as nodules  with primary exposures in Tishomingo County, Mississippi, Colbert County, Alabama, and the Black Warrior Basin in Alabama.  The formation extends from northeastern Mississippi through northern Alabama into northwestern Georgia and into Tennessee.  The St. Louis Formation of Kentucky is considered an extension of the Tuscumbia Formation.  The Carmack Formation (Carmack Chert) was included in the Tuscumbia Limestone Formation.
