Is Marble A Foliated Metamorphic Rock Explain

It has a greater number of potential uses than almost any other rock type.

Is marble a foliated metamorphic rock explain.

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. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone. Nonfoliated metamorphic rocks are identified on the basis of their composition.

It is composed primarily of calcium carbonate. Foliated metamorphic rocks are formed within the earth s interior under extremely high pressures that are unequal occurring when the pressure is greater in one direction than in the others directed pressure. The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization. This causes the minerals in the original rock to reorient themselves with the long and flat minerals aligning perpendicular to the greatest pressure direction.

Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Quartzite composed of the mineral quartz. The specimen shown above is about two inches five centimeters across. 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.

Marble is considered a non foliated metamorphic rock because the mineral crystals aren t well aligned. Marble composed of the mineral calcite. In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is typically not foliated although there are exceptions.

Sandstone is defined as a rock which is composed of sand sized grains of various minerals mostly of uniform size and often are smooth and rounded. If you had two metamorphic rocks one that has garnet crystals and the other that has chlorite crystals which one could have formed at a deeper level in earth s crust. Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone. Some kinds of metamorphic rocks granite gneiss and biotite schist are two examples are strongly banded or foliated.
