Summary:
Cutnose Formation of Wedowee Group is here formally named for exposures along Cutnose Creek in the northeastern part of Randolph Co., eastern AL. Consists predominantly of feldspathic biotite gneiss, fine-grained, graphite-chlorite-sericite schist and locally, graphite-quartz-sericite phyllite. Units are cyclically interbedded and apparently correspond to an original sedimentary sequence of graywacke, litharenite, pelitic arenite and pelite. Most characteristic feature of the Cutnose is the many interbeds of biotite feldspathic gneiss. Because of possible local folding, true total thickness of Cutnose is undetermined. Overlies Cragford Phyllite, also of Wedowee. Age shown as middle Paleozoic.

Summary:
Cutnose Formation of Neathery and Reynolds (1975) is here referred to as Cutnose Gneiss of Wedowee Group. Described as cyclically interbedded fine-grained quartz-biotite-feldspar gneiss, fine-grained graphite-chlorite-sericite schist, and locally graphite-quartz-sericite phyllite and quartzite. Overlies Cragford Phyllite.

Summary:
In the New Site quadrangle, three interlayered and gradational sequences of the Cutnose Gneiss (Wedowee Group) are noted: 1) arenaceous garnet biotite chlorite sericite phyllite; 2) interlayered arenaceous garnet biotite chlorite sericite phyllite, biotite chlorite sericite phyllite and graphite phyllite; and 3) graphite phyllite. Excellent exposures in small quarry northeast of the light-duty road, sec. 28, T24N, R22E.
