Is Marble An Example Of Metamorphic Rock

Common metamorphic rocks include phyllite schist gneiss quartzite and marble.

Is marble an example of metamorphic rock.

Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure. Marble is a metamorphic rock that comes from metamorphosed limestone or dolomite. 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. Examples of metamorphic rocks.

Some examples of metamorphic rocks are gneiss slate marble schist and quartzite. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 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.

There are hundreds of metamorphic rocks across the face of the earth with different compositions and textures. 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. In this hand specimen of vermont marble the crystals are small. Other examples include quartzite hornfels and novaculite.

Marble is typically not foliated although there are exceptions. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. The extensively known example of non foliated metamorphic rock is a marble. Slate is another common metamorphic rock that forms from shale.

Non foliated metamorphic rocks do not have a banded or layered appearance. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite. Examples of common metamorphic rocks quartzite is a coarse grained metamorphic rock derived from sandstone. In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
