Is Marble A Foliated Rock

Some non foliated rocks include marble amphibolite and quartzite.

Is marble a foliated rock.

Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust. Lapis lazuli the famous blue gem material is actually a metamorphic rock. The minerals in the rock are aligned and look platey or banded according to how pressure was applied to the rock during that phase.

The specimen shown above is about two inches five centimeters across. It is composed primarily of calcium carbonate. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone.

Also foliated rocks have visible layers or elongated grains of minerals. Some examples of non foliated metamorphic rocks include quartzite marble amphibolite and hornfels. 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. Marble is a non foliated metamorphic rock.

Regional contact and cataclastic. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. Marble is commonly used for sculpture and as a building material.

Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone. Slate is another common metamorphic rock that forms from shale. Nonfoliated does not have distinct layers or bands. Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created.

Examples of foliated metamorphic rocks would be schist gneiss and slate. Generally metamorphic rock and the metamorphic processes can be divided into three categories.
