Marble Is An Example Of Metamorphic Rock

Marble is a metamorphic rock that is formed from the sedimentary rock limestone.

Marble is an example of metamorphic rock.

Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure. Examples of metamorphic rocks. 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. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Non foliated metamorphic rocks do not have a banded or layered appearance. Pictures and brief descriptions of some common types. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance.

The table below shows examples of common metamorphic rocks. There are hundreds of metamorphic rocks across the face of the earth with different compositions and. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Composed of quartz feldspar and mica.

Its composition is equal to that of granite but forms alternating layers of clear and dark minerals. 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. 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.

Anthracite is a type of coal with a high carbon count few impurities and with a high luster meaning it looks shiny. Marble is commonly used for sculpture and as a building material.

Slate is another common metamorphic rock that forms from shale. In this hand specimen of vermont marble the crystals are small. Examples of metamorphic rocks. Examples of metamorphic rocks include anthracite quartzite marble slate granulite gneiss and schist.

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. Remember these rocks are formed under extreme heat and pressure.
