If a metamorphic rock has a strong, parallel alignment of coarse mice flakes and/or of different mineral bands, this is called?

What process would exhibit sheared and mechanically fragmented rocks?

Describe contact metamorphism.

What forms from the metamorphism of limestone or dolostone?

What foliated metamorphic rock is texturally intermediate between slate and schist?

What metamorphic rock is characterized by the segregation of light- and dark-colored minerals into thin layers or bands?

What type of foliation results from the parallel alignment of abundant, coarse-grained, mica flakes in a metamorphic rock?

What metamorphic rock could be used to neutralize acidic mine waters?

List all of the foliated metamorphic rocks in the order of increasing grain size and increasing grade of metamorphism.

Which metamorphic rocks are typically formed by the metamorphism of sandstone?

What is the major source of heat for contact metamorphism?

Which setting would regional metamorphism is most likely?

If graphite is identified in a particular schist, describe the parent rock and metamorphic history.

What term describes the zone of contact metamorphism surrounding an intrusive magma body?

During metamorphism, what is the major effect of chemically active fluids?

What two metamorphic rocks are composed predominantly of single minerals?

Are slate and schist both derived by metamorphism of shales and mudstones?

Is calcite the main mineral constituent of the sedimentary rock limestone and of the metamorphic rock marble?

Do metamorphic rocks formed during episodes of mountain building typically show textural characteristics indicative of shearing stress and deformation?

At high pressures and elevated temperatures of regional metamorphism are silicate rocks more resistant to flowage and deformation than at low temperature and pressures?

Are foliated metamorphic rocks composed largely of equidimensional grains of minerals such as quartz and calcite?

Is rock cleavage or slaty cleavage in slates largely a consequence of abundant, parallel-aligned, very fine-grained mica flakes in the rock?

Are muscovite, biotite, and chlorite common minerals found in phyllites and schists?

Are the distinctive layers or bands of different minerals in gneisses indicative of complex folding?
