Marble Is An Igneous Rock

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.

Marble is an igneous rock.

Even rocks a seemingly constant substance can change into a new type of rock. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Sedimentary igneous and metamorphic. Marble is commonly used for sculpture and as a building material.

Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Sedimentary and igneous rocks began as something other than rock. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral.

Igneous rocks from the latin word for fire form when hot molten rock crystallizes and solidifies. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the. Igneous rocks are divided into two groups intrusive or extrusive depending upon where the molten rock solidifies. It forms from the slow crystallization of magma below earth s surface.

In the rock cycle there are three different types of rocks. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.
