Marble Nonfoliated Metamorphic Rock

Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone.

Marble nonfoliated metamorphic rock.

Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone. Quartzite composed of the mineral quartz. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust.

Marble composed of the mineral calcite. It is composed primarily of calcium carbonate. It is formed by the metamorphism or limestone. Hornfels have no specific composition while amphibolites are formed from hornblende and plagioclase.

Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite. Marble is mainly composed of calcium carbonate. Quartzite is made of metamorphosed sandstone while marble is formed from limestone that was metamorphosed. Gneiss is a foliated metamorphic rock made of silicate.

Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created. Marble is among the non foliated metamorphic rocks produced from the metamorphism of dolostone or limestone. It takes high polish and is often used for sculpture and as building material. Marble is a nonfoliated metamorphic rock made of carbonate minerals particularly calcite.

In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. The specimen shown above is about two inches five centimeters across. Marble is typically not foliated although there are exceptions.
