Summary:

Hatchet Creek Group is here named in Coosa, Elmore, and Chilton Cos, of east-central Alabama. Described as sequence of dense fine- to coarse-textured schist and gneiss divided into Hanover Schist (new name) and Pinchoulee Gneiss (new name). Locally, highly feldspathized and intruded by leucocratic granitoid plutons. Structurally underlies Wedowee Group. Affected by late metamorphic event sometime before 317 Ma, therefore age is middle Paleozoic or older.
