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.
Is marble a foliated metamorphic rock explain.
In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
This causes the minerals in the original rock to reorient themselves with the long and flat minerals aligning perpendicular to the greatest pressure direction.
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.
Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met.
Marble composed of the mineral calcite.
Slate is another common metamorphic rock that forms from shale.
It has a greater number of potential uses than almost any other rock type.
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.
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.
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.
It is composed primarily of calcium carbonate.
Nonfoliated metamorphic rocks are identified on the basis of their composition.
Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite.
Marble is typically not foliated although there are exceptions.
Some kinds of metamorphic rocks granite gneiss and biotite schist are two examples are strongly banded or foliated.
The pressure applied to the reforming rock causes the differences in the way the rock looks once recrystallized and determines whether it will be foliated or nonfoliated.
The specimen shown above is about two inches five centimeters across.
The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization.
Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone.
