Metamorphic Rocks
Foliated Rocks
Phyllite- layered rock, resembling the grain size of slate and schist sediments
Talc Schist- composed of layered minerals talc and mica
Amphibolite- consists of amphiboles and feldspar- may show foliation (layers)
Slate- metamorphosed shale- very fine texture and splits cleanly along layers
Garnet Schist- composed mostly of small flakes of mica with larger crystals of
garnet
Chlorite Schist- composed of medium-sized grains and layers of chlorite and mica
Mica Schist- composed of small layered flakes of muscovite and biotite
Graphite Schist- composed mostly of graphite layers
Gneiss (pronounced “nice”)- formed from either granite or sedimentary rocks,
showing layering of mica, quartz, and feldspar crystals
Non Foliated Rocks
Anthracite- metamorphosed coal
Hornfels- fine-grained, non-schist rock
Serpentine Marble- recrystallized limestone (calcite) containing some other rock
remains- impure
Marble- recrystallized limestone (calcite) – pure
Serpentinite- metamorphosed serpentine rock
Quartzite- metamorphosed sandstone, which is partially recrystallized
