Foliated metamorphic rocks possess ____________.
A)leafy plant fossils (ancient foliage)
B)a homogenous 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 sea water

Question

Quizplus · Accepted Answer

Foliated metamorphic rocks have a planar fabric consisting of mineral grains in preferred orientations or preferred patterns of association (banding). This occurs due to the pressure and heat causing the minerals to align in the direction of stress, resulting in the banded appearance. Leafy plant fossils are not necessarily present in foliated metamorphic rocks, and their texture is not homogenous, but rather stratified. Minerals in metamorphic rocks can come from a range of sources, including pre-existing rocks and mineral deposition from fluids, but not always directly from seawater.
