Answer to Question 1

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



Answer to Question 2

Metamorphic rocks are primarily classified according to their texture. In a foliated texture, platy and
elongate minerals have a preferred orientation. A nonfoliated texture does not exhibit any discernable
preferred orientation of the mineral grains
