Marble Is An Example Of Metamorphic Rock

Its basic component is calcium carbonate.

Marble is an example of metamorphic rock.

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. 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. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock.

Composed of quartz feldspar and mica. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Remember these rocks are formed under extreme heat 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.

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. Non foliated metamorphic rocks do not have a banded or layered appearance. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance. Anthracite is a type of coal with a high carbon count few impurities and with a high luster meaning it looks shiny.

Examples of metamorphic rocks include anthracite quartzite marble slate granulite gneiss and schist. The table below shows examples of common metamorphic rocks. The extensively known example of non foliated metamorphic rock is a marble. Marble is a metamorphic rock that is formed from the sedimentary rock limestone.

Marble is commonly used for sculpture and as a building material. There are hundreds of metamorphic rocks across the face of the earth with different compositions and. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Slate is another common metamorphic rock that forms from shale.

Compact metamorphic rock that evolved from limestone rocks subjected to high temperature 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.

In this hand specimen of vermont marble the crystals are small. Examples of metamorphic rocks.
