Phyllonitic foliation and shear band cleavage are the dominant foliations(S1) and shear band cleavage are the dominant foliations in the lustrous Metcalf Phyllite. The Brunton compass rests parallel to the S2 folilation
The Metcalf Phyllite is a gray to green phyllite and sometimes a metasiltstone with rare thin beds of fine-grained metasandstone. The rock is termed a tectonite that was transformed into a lustrous, fine-grained phyllite by shearing near thrust faults. Fine laminations may be silt beds similar to the Pigeon Siltstone exposed east of Pigeon Forge.
