An igneous rock is made by cooling of magma inside the earth crust or lava in the surface of earth.
Marble igneous rock.
Pumice is an extrusive igneous rock.
Igneous rocks cool from molten magma and form the majority of the crust.
Calcite dolomite limestone and marble are part of the carbonate group which is based on calcium and oxygen.
Marble is formed by metamorphism of sedimentary rock such as limestone.
Marble is essentially a granular metamorphic rock composed chiefly of recrystallised limestone chief mineral as calcite.
Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures.
Most igneous rocks are made up of minerals which are part of the silicate group.
This means that they are primarily based on silicon and oxygen.
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.
Marble is not an igneous rock.
Granite is an intrusive igneous rock.
A marble is a sedimentary metamorphic or igneous.
Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques.
