Marble Is An Example Of Metamorphic Rock

Pictures and brief descriptions of some common types.

Marble is an example of metamorphic rock.

Marble is commonly used for sculpture and as a building material. Examples of metamorphic rocks include anthracite quartzite marble slate granulite gneiss and schist. Anthracite is a type of coal with a high carbon count few impurities and with a high luster meaning it looks shiny. There are hundreds of metamorphic rocks across the face of the earth with different compositions and.

The table below shows examples of common metamorphic rocks. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance. Examples of metamorphic rocks.

Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is a metamorphic rock that is formed from the sedimentary rock limestone. Examples of metamorphic rocks. Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure.

Composed of quartz feldspar and mica. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Slate is another common metamorphic rock that forms from shale. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.

Its basic component is calcium carbonate. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. In this hand specimen of vermont marble the crystals are small.

Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window. Remember these rocks are formed under extreme heat and pressure. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Learn more about metamorphic rocks here.

Other examples include quartzite hornfels and novaculite. Foliated metamorphic rocks such as gneiss phyllite schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.
