Question

Quizplus · Accepted Answer

Schistosity is a type of foliation defined by the preferred orientation of large crystals of mica. Slaty cleavage is defined by the parallel alignment of minerals like clay or mica, but not necessarily large crystals of mica. Phyllitic luster refers to the silky sheen of a rock's surface, but it is not a type of foliation. Compositional banding is not related to foliation at all, but rather refers to alternating layers of different rock types within a larger rock unit.
