What Is Foliated Marble
The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization.
What is foliated marble. Gneiss night dark is thought to form by partial melting and in situ crystallization of the melted portion. Marble is commonly used for sculpture and as a building material. The specimen shown above is about two inches five centimeters across. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone.

It has a greater number of potential uses than almost any other rock type. Marble is a completely non foliated rock.
Marble is a non foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time slate is a fine grained foliated homogeneous metamorphic rock derived from an original shale type sedimentary rock composed of clay or volcanic ash through low.
