Marble Nonfoliated Metamorphic Rock

Marble is mainly composed of calcium carbonate.

Marble nonfoliated metamorphic rock.

Hornfels have no specific composition while amphibolites are formed from hornblende and plagioclase. Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created. It is formed by the metamorphism or limestone. It has a greater number of potential uses than almost any other rock type.

Marble is typically not foliated although there are exceptions. Marble composed of the mineral calcite. Quartzite is made of metamorphosed sandstone while marble is formed from limestone that was metamorphosed. Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock.

Marble is a nonfoliated metamorphic rock made of carbonate minerals particularly calcite. Nonfoliated metamorphic rocks are identified on the basis of their composition. Gneiss is a foliated metamorphic rock made of silicate. The specimen shown above is about two inches five centimeters across.

These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust. It takes high polish and is often used for sculpture and as building material. Different types of rocks and minerals can form non foliated metamorphic rocks. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone.

In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is among the non foliated metamorphic rocks produced from the metamorphism of dolostone or limestone. Quartzite composed of the mineral quartz.
