Metamorphic Rocks Test

Front

What are the three principal agents of metamorphism?

Back

Heat, pressure, and chemically reactive fluids.

Front

Which metamorphic rock is characterized by distinct banding of light and dark minerals?

Back

Gneisses.

Front

What is the significance of index minerals in metamorphic rocks?

Back

They help determine the temperature and pressure conditions during metamorphism.

Front

Which metamorphic texture describes minerals oriented flat and parallel to each other?

Back

Foliated.

Front

The protolith of slate is:

Back

Shale.

Front

What is metamorphism?

Back

The process by which rocks are altered in mineralogy, texture, and chemical composition due to changes in temperature and pressure.

Front

What is the difference between foliated and non-foliated metamorphic rocks?

Back

Foliated rocks have a layered or banded appearance due to the alignment of minerals, while non-foliated rocks do not exhibit this layering.

Front

What is the protolith of marble?

Back

Limestone.

Front

What role do chemically reactive fluids play in metamorphism?

Back

They facilitate the exchange of ions and promote chemical reactions that alter the mineral composition of the rock.

Front

What is the process of regional metamorphism?

Back

Metamorphism that occurs over large areas under high pressure and temperature, typically associated with tectonic forces.
