    ERB-02

    This sample is a strongly mylonitized pelitic schist with a continuous schistoscity defined by strongly alligned biotite, fibrous sillimanite, and opaques and interspersed with discontinuous quartz and k-feldspar ribbons. K-feldspar is strongly sericitized. The sense of shear is ambiguous.

    ERB-01

    Anastamosing spaced schistocity defined by aligned elongate minerals including biotite, hornblende, garnet, and opaques. Foliation wraps quartz and k-feldpsar porphyroclasts with core-mantle textures and subgrain development in the old grains. K-feldspar is strongly sericitized. The sense of shear is ambiguous.
