List of Metamorphic Rocks

Gneiss. Gneiss is a banded rock, composed of the same minerals as granite, syenite, diorite, gabbro, etc., the crystals of which are mostly large enough to be seen. Thus there are varieties called granite-gneiss, diorite-gneiss, gabbro-gneiss, etc., Gneiss made by metamorphosis of a sedimentary rock is called para-gneiss.
