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

Question

Quizplus · Accepted Answer

Foliated metamorphic rocks have mineral grains that are arranged in specific patterns or orientations, such as banding or layering. This is the result of the rock being subjected to pressure and heat, causing minerals to align in specific directions. Leafy plant fossils (A) are not necessarily present in foliated metamorphic rocks, and (B) is incorrect as a homogeneous texture would indicate a lack of preferred orientation. (D) is also incorrect as minerals in metamorphic rocks do not necessarily precipitate directly from seawater.
