Which of the following would exhibit sheared and mechanically fragmented rocks?

What type of stress (pressure) is illustrated in the diagram below?

Hydrothermal metamorphism involves chemical reactions between hot fluids and surrounding rocks such as occurs beneath mid ocean ridges.

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

What metamorphic rock forms by contact metamorphism of mudstones and shales?

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

Which of the following best describes the conditions of contact metamorphism?

Which of the following metamorphic rocks forms from the metamorphism of limestone or dolostone?

Which of the following terms describes the strong, parallel alignment of course mica flakes and/ or of different bands in metamorphic rock?

What platy, parallel, mineral grains are the most visual aspect of foliated metamorphic rocks?

Foliated metamorphic rocks are composed largely of equidmensional grains of minerals such as quartz and calcite.

Which low grade metamorphic rock, composed of extremely fine sized mica and other mineral grains, typically exhibits well developed rock cleavage?

Calcite is the main mineral constituent of the sedimentary rock limestone and metamorphic rock.

Which of the following metamorphic rocks forms at the highest grade of regional metamorphism?

What metamorphic rock is thought to form by partial melting and in situ crystallization of the melted portion?

Which of the following metamorphic rocks is characterized by the segregation of the light and dark colored minerals into thin layers or bands?

Which of the following metamorphic rocks typically forms by metamorphism of sandstone?

Which of the following is not likely to be genetically associated with impact of and asteroid or large meteorite?

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

Which of the following metamorphic rocks forms at very high pressures but moderately low temperatures associated with subduction of oceanic crust sediments?

In which setting would regional metamorphism be most likely?

Amphibolite is a foliated metamorphic rock composed principally of hornblende and plagioclase. How does it form?
