This rock has been cut on three mutually perpendicular planes. The top plane is parallel to the foliation, and a lineation can be seen on that surface. The foliation is best seen on the cut face on the lower right. The foliation is less visible on the cut face to the lower left. These rocks either represent an originally layered protolith rock, original non-layer inhomogeneities that have been stretched out, or later formed inhomogeneities such as thin intruded dikes.
Minerals are easily visible and identifiable by eye or with a hand lens.
Sheet silicates are not abundant. Augen are large crystals that were molded into eye-like shapes during strong deformation. The equant and crystalline form of the garnets indicate that they grew largely after any deformation. Porphyroblasts of garnet in a muscovite schist. The equant and crystalline form of the garnets indicate that they grew largely after deformation had finished.
