Is Marble A Foliated Rock

Examples of foliated metamorphic rocks would be schist gneiss and slate.

Is marble a foliated rock.

Generally metamorphic rock and the metamorphic processes can be divided into three categories. Lapis lazuli the famous blue gem material is actually a metamorphic rock. Marble is commonly used for sculpture and as a building material. Both foliated and nonfoliated rocks begin their lives as either sedimentary igneous or another metamorphic rock.

Marble is a non foliated metamorphic rock. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone. Nonfoliated does not have distinct layers or bands. Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone.

Some non foliated rocks include marble amphibolite and quartzite. It is composed primarily of calcium carbonate. 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. Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created.

Some examples of non foliated metamorphic rocks include quartzite marble amphibolite and hornfels. Non foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non layered or banded appearance. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Slate is another common metamorphic rock that forms from shale.

Regional contact and cataclastic. It has a greater number of potential uses than almost any other rock type. The specimen shown above is about two inches five centimeters across. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth.

These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust. The minerals in the rock are aligned and look platey or banded according to how pressure was applied to the rock during that phase.
