Marble Igneous Rock

Marble is not an igneous rock.

Marble igneous rock.

Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. A marble is a sedimentary metamorphic or igneous. While marble is a non folliated metamorphic rock. An igneous rock is made by cooling of magma inside the earth crust or lava in the surface of earth.

Marble granular limestone or dolomite i e rock composed of calcium magnesium carbonate that has been recrystallized under the influence of heat pressure and aqueous solutions. Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. Granite is an intrusive igneous rock.

Igneous rocks cool from molten magma and form the majority of the crust. This means that they are primarily based on silicon and oxygen. Calcite dolomite limestone and marble are part of the carbonate group which is based on calcium and oxygen. Pumice is an extrusive igneous rock.

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. Marble is essentially a granular metamorphic rock composed chiefly of recrystallised limestone chief mineral as calcite.
