Is Marble An Example Of Metamorphic Rock

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

Is marble an example of metamorphic rock.

Marble is a metamorphic rock that comes from metamorphosed limestone or dolomite. Its basic component is calcium carbonate. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure.

This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Examples of common metamorphic rocks quartzite is a coarse grained metamorphic rock derived from sandstone. In this hand specimen of vermont marble the crystals are small. Regressive metamorphism occurs when a rock that evolved at great depth where there is greater pressure and heat and when approaching the surface becomes unstable and evolves.

Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Some examples of metamorphic rocks are gneiss slate marble schist and quartzite. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite. Non foliated metamorphic rocks do not have a banded or layered appearance.

Examples of metamorphic rocks. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. There are hundreds of metamorphic rocks across the face of the earth with different compositions and textures. The extensively known example of non foliated metamorphic rock is a marble.

In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is typically not foliated although there are exceptions. 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. Common metamorphic rocks include phyllite schist gneiss quartzite and marble.
