Q:

What are metamorphic rocks used for?

A:

Metamorphic rocks are used for roofing material, decorative gardening stone, the base for snooker tables, building material, sculpture material and paving material. Metamorphic rocks come in three different types: slate, marble and schist.

Slate starts out as shale under the surface of the Earth before its metamorphosis. It is typically gray in color and splits along long flat planes. It is also does not allow water or other liquids to pass through it. Slate is most often used as a roofing material, decorative gardening stone and a base for snooker tables. In the Victorian era, it was commonly used as a writing board.

Marble is another one of the metamorphic rocks and is a metamorphosed limestone. It has a hard crystalline rock appearance and was the stone of choice in ancient Greece. In fact, more than 22,000 tonnes of marble were used to build the ancient Greek Parthenon and marble remains a popular building and sculpture material today. It can also be ground down to make cleaning products or soaps.

Schist is another metamorphic rock that is formed from either mud or shale. However, it is formed at a much higher temperature than slate is. Schist is a fairly weak rock so it does not make for a good building material. It is used for paving and occasionally sculpture.

  • Q:

    What are metamorphic rocks?

    A:

    Metamorphic rocks are formed when the properties of existing igneous or sedimentary rocks are altered by contact with heat or pressure. They are typically found deep underground where the conditions necessary for their formation exist.

  • Q:

    How are metamorphic rocks classified?

    A:

    Metamorphic rocks are primarily classified according to mineral composition and texture, similar to how igneous or sedimentary rocks are classified. However, the forces that form metamorphic rocks, namely pressure, heat and chemically active fluids, can produce a wide range of different substances, which makes classifying these rocks much more difficult.

  • Q:

    Where can metamorphic rocks be found?

    A:

    Metamorphic rocks are most often found in mountainous regions though they can be seen wherever there are signs of geological upheaval in an area. This type of rock is formed by the transformation of another rock type, a change that is usually triggered by tremendous heat, pressure or other violent phenomena. The forces that cause metamorphic rocks to form are so great that they change not only the appearance but also the chemical composition of an existing rock.

  • Q:

    How do metamorphic rocks form?

    A:

    Metamorphic rocks are formed due to physical and chemical processes, such as heat, pressure and mineral exposure, that change the composition of pre-existing igneous, sedimentary and metamorphic rocks. These processes may be singular, but commonly occur simultaneously.
