Is Marble A Foliated Rock

The specimen shown above is about two inches five centimeters across.

Is marble a foliated rock.

Generally metamorphic rock and the metamorphic processes can be divided into three categories. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust. It is composed primarily of calcium carbonate. It has a greater number of potential uses than almost any other rock type.

Slate is another common metamorphic rock that forms from shale. The minerals in the rock are aligned and look platey or banded according to how pressure was applied to the rock during that phase. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration. Also foliated rocks have visible layers or elongated grains of minerals.

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. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created. Lapis lazuli the famous blue gem material is actually a metamorphic rock.

Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Examples of foliated metamorphic rocks would be schist gneiss and slate. Some non foliated rocks include marble amphibolite and quartzite.

Nonfoliated does not have distinct layers or bands. Regional contact and cataclastic. Marble is commonly used for sculpture and as a building material. Marble is a non foliated metamorphic rock.

Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone. Non foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non layered or banded appearance.
