Marble Igneous Rock

Most igneous rocks are made up of minerals which are part of the silicate group.

Marble igneous rock.

Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. 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. Calcite dolomite limestone and marble are part of the carbonate group which is based on calcium and oxygen. An igneous rock is made by cooling of magma inside the earth crust or lava in the surface of earth.

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 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 that forms when limestone is subjected to the heat and pressure of metamorphism. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. While marble is a non folliated metamorphic rock. A marble is a sedimentary metamorphic or igneous.

Granite is an intrusive igneous rock. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques.
