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.

Sedimentary and igneous rocks began as something other than rock. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. It forms from the slow crystallization of magma below earth s surface.

Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the. Sedimentary igneous and metamorphic. The melt originates deep within the earth near active plate boundaries or hot spots then rises toward the surface.

Igneous rocks are divided into two groups intrusive or extrusive depending upon where the molten rock solidifies. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble is commonly used for sculpture and as a building material.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. 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.
