Exam 6: Formation of Metamorphic Rocks

If a rock containing kyanite and andalusite were to undergo a decrease in pressure, what must happen to temperature in order for that rock to continue to have stable kyanite and andalusite?

Coal metamorphosed to medium metamorphic grade would become a(n)

How are metamorphic rocks classified?

A well know example of a paired metamorphic belt occurs in

Metamorphic rocks can form from the metamorphism of igneous, sedimentary and metamorphic rocks.

Which rock is described below? "This first-formed metamorphic rock preferentially splits along planes of parallel microscopic micas."

Which process makes it the most difficult to trace metamorphic rocks to their parent rocks?

In what type of metamorphism does this reaction occur? KAl3Si3O10(OH)2 + SiO2 --> Al2SiO5 + KAlSi3O8 + H2O

Metamorphic processes can be seen because metamorphic rocks form on Earth's surface.

Which is not a clue indicating that hornfels forms under conditions of high temperature but not high pressure?

Temperature decreases with depth below Earth's surface.

How might hydrothermal ore genesis occur?

A weakly foliated metamorphic rock composed of quartz is classified as a

A weakly foliated metamorphic rock composed of calcite is classified as a

An anhydrous, very-high grade metamorphic rock composed of garnet and pyroxene is classified as a(n)

How does foliation occur?

What grade of metamorphism occurs at a depth of 19 km and a temperature of 700 degrees C?

If a rock containing andalusite and sillimanite were to undergo an increase in pressure, what must happen to temperature in order for that rock to continue to have stable andalusite and sillimanite?

What is different between quartz and quartzite's formation processes?

A coarse-grained, shiny, foliated metamorphic rock that exhibits well developed mineral cleavage is classified as a
