Foliated metamorphic rocks possess ____________.
A) leafy plant fossils (ancient foliage)
B) a homogeneous texture resulting from randomly oriented grains
C) a planar fabric consisting of mineral grains in preferred orientations or preferred patterns of association (banding)
D) minerals precipitated directly from seawater

Question

Quizplus · Accepted Answer

Foliated metamorphic rocks are characterized by a planar fabric consisting of mineral grains in preferred orientations or preferred patterns of association (banding). This banding or preferred orientation of mineral grains is the result of directed pressure or stress during the formation process, and can result in visible layers or "foliations" in the rock. Foliated metamorphic rocks do not necessarily contain plant fossils or have a homogeneous texture resulting from randomly oriented grains. They also may not have minerals precipitated directly from seawater.
