Figure 3. Collage of some lithologies and fabric relations from the Uchee terrane. (A) Layered orthogneisses and paragneisses of the Phenix City Gneiss. (B) Outcrop photo of Phenix City Gneiss containing two sets of planar fabrics. S₀/S₁ is the composite compositional layering (bedding?; S₀) and coplanar upper amphibolite-facies schistosity (S₁), and S₂ is an amphibolite-facies schistosity axial planar to ptygmatic F₂ folds. (C) Migmatized North Columbus metamorphic complex gneiss, from which sample A-13 was collected. Note blocks of gneiss containing S₀/S₁ gneissosity at a high angle to S₂ within encapsulating leucosome. (D) Moffits Mill Schist at the type locality at Moffits Mill, Little Uchee Creek. Sample UB-1-03 was collected from this outcrop. (E) Close-up view of slabbed and polished Motts Gneiss sample with characteristic L₂ mineral stretching lineation. Dime (1.8 cm diameter) for scale. (F) Two sets of foliations developed in a folded and sheared Moffits Mill Schist sample (from McRae, 1992). S₀/S₁ is the composite compositional layering (bedding?; S₀) and coplanar upper amphibolite-facies schistosity (S₁). Middle amphibolite-facies foliation (S2) is axial planar to small-scale open folds and parallels the sheared margin of a granitoidal injection along right-hand edge of the sample. Scale is marked in squares with one-centimeter sides.
