How are foliated metamorphic rocks classified? Describe some of the rock types found at different

grades of foliated metamorphic rocks. What will be an ideal response?


Foliated metamorphic rocks can be arranged in order of increasing grain size, perfection of their
foliation, or both. Slate is fine-grained, followed by (in increasingly larger grain size) phyllite and
schist; gneiss displays segregated bands of minerals. Amphibolite is another fairly common foliated
metamorphic rock. Migmatities have both igneous and high-grade metamorphic characteristics
