Marble Is An Example Of Metamorphic Rock

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Marble is an example of metamorphic rock.

Its composition is equal to that of granite but forms alternating layers of clear and dark minerals. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Other examples include quartzite hornfels and novaculite. 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 made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Remember these rocks are formed under extreme heat and pressure. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met.

Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window. The extensively known example of non foliated metamorphic rock is a marble.

Anthracite is a type of coal with a high carbon count few impurities and with a high luster meaning it looks shiny. Pictures and brief descriptions of some common types. The table below shows examples of common metamorphic rocks. Non foliated metamorphic rocks do not have a banded or layered appearance.

In this hand specimen of vermont marble the crystals are small. 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. Slate is another common metamorphic rock that forms from shale.

Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance. Marble is commonly used for sculpture and as a building material. Composed of quartz feldspar and mica. Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure.

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. Its basic component is calcium carbonate.
