Exam 8: Metamorphism and Metamorphic Rocks

Migmatites are the result of ___________-grade metamorphism.

As an agent of metamorphism ___________ ___________ promotes metamorphism by increasing rates of chemical reactions/by carrying ions in solution?

The blueschist facies is associated with relatively low temperature and high pressure along subduction zones.

Which mineral group is the source of most commercial asbestos?

Although metamorphism involves changes occurring in the solid state, pore fluids play an important role in transporting ions in solution.

Is the concept of metamorphic facies applicable to all rock types? Explain

Name five metamorphic rocks or minerals which have an economic use. After each, give a use for the rock or mineral.

Metamorphism of a mudstone will produce slate, schist, gneiss, and hornfels.

The concept of metamorphic facies applies to any type of parent rock.

What are some of the analytical techniques which geologists have employed to help determine the authenticity of historical marble artworks such as sculptures and artifacts?

Foliated metamorphic textures form under which of the following circumstances?

What is the most important fluid which can promote metamorphism?

Lithostatic pressure will cause a rock to be compressed equally in all directions.

An isograd represents a line of equal metamorphic intensity or grade.

The word elements meta and morph are Latin for

Which of the following correctly lists metamorphic mineral assemblages in order of decreasing temperature/pressure of formation?

Metamorphic rocks are generally older than sedimentary and igneous rocks.

Is most of the world's commercial graphite production presently of natural or synthetic graphite?

Heat that results in metamorphism is the result igneous intrusions and from deep burial.

The pressure involved in regional metamorphism is differential pressure.
