Summary:
Name Eulie shale applied at Bransford to soft argillaceous shale in three gray, yellowish, or greenish layers within the Chattanooga shale. Top layer at this locality consists of nodules. It is a single layer of greenish shale with nodules at the base at Westmoreland. Thickness 6 to 9 in. Overlies Gassaway shale (new); underlies Westmoreland shale (new). The Eulie and Westmoreland are complementary in their stratigraphic relations. The absence of either would make determination of the status of the other difficult. Age assigned is Early Mississippian.
