Marble Is An Igneous Rock

Even rocks a seemingly constant substance can change into a new type of rock.

Marble is an igneous rock.

It forms from the slow crystallization of magma below earth s surface. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the. Sedimentary igneous and metamorphic. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.

Sedimentary and igneous rocks began as something other than rock. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. In the rock cycle there are three different types of rocks. Igneous rocks are divided into two groups intrusive or extrusive depending upon where the molten rock solidifies.

Marble is commonly used for sculpture and as a building material. The melt originates deep within the earth near active plate boundaries or hot spots then rises toward the surface. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Igneous rocks from the latin word for fire form when hot molten rock crystallizes and solidifies.

Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.
