Marble Is An Example Of Metamorphic Rock

Anthracite is a type of coal with a high carbon count few impurities and with a high luster meaning it looks shiny.

Marble is an example of metamorphic rock.

Slate is another common metamorphic rock that forms from shale. Examples of metamorphic rocks. Examples of metamorphic rocks. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met.

Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Marble is a metamorphic rock that is formed from the sedimentary rock limestone. The table below shows examples of common metamorphic rocks. Remember these rocks are formed under extreme heat and pressure.

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 commonly used for sculpture and as a building material. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance. Composed of quartz feldspar and mica.

Other examples include quartzite hornfels and novaculite. Learn more about metamorphic rocks here. 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. Its composition is equal to that of granite but forms alternating layers of clear and dark minerals.

Non foliated metamorphic rocks do not have a banded or layered appearance. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Examples of metamorphic rocks include anthracite quartzite marble slate granulite gneiss and schist. The extensively known example of non foliated metamorphic rock is a marble.

Pictures and brief descriptions of some common types. 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 that forms when limestone is subjected to the heat and pressure of metamorphism. There are hundreds of metamorphic rocks across the face of the earth with different compositions and.

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