Is Marble A Foliated Metamorphic Rock Explain
Marble composed of the mineral calcite.
Is marble a foliated metamorphic rock explain. Marble is considered a non foliated metamorphic rock because the mineral crystals aren t well aligned. 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. This causes the minerals in the original rock to reorient themselves with the long and flat minerals aligning perpendicular to the greatest pressure direction. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met.
Common metamorphic rocks include phyllite schist gneiss quartzite and marble. 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. It has a greater number of potential uses than almost any other rock type. Some kinds of metamorphic rocks granite gneiss and biotite schist are two examples are strongly banded or foliated.
Quartzite composed of the mineral quartz. 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. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Marble is a non foliated metamorphic rock that forms through the metamorphism of limestone.
It is composed primarily of calcium carbonate. The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization. Nonfoliated metamorphic rocks are identified on the basis of their composition. 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.
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 typically not foliated although there are exceptions. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite. Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone.
