Marble Igneous Rock

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

Marble igneous rock.

Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. Most igneous rocks are made up of minerals which are part of the silicate group. Granite is an intrusive 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. An igneous rock is made by cooling of magma inside the earth crust or lava in the surface of earth. Marble is formed by metamorphism of sedimentary rock such as limestone. 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.

While marble is a non folliated metamorphic rock. Pumice is an extrusive igneous rock. This means that they are primarily based on silicon and oxygen. Igneous rocks cool from molten magma and form the majority of the crust.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble is not an igneous rock.
