Igneous rock marble.
Calcite dolomite limestone and marble are part of the carbonate group which is based on calcium and oxygen.
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 formed when limestone is subjected to high pressure or heat.
The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the.
The melt originates deep within the earth near active plate boundaries or hot spots then rises toward the surface.
Most igneous rocks are made up of minerals which are part of the silicate group.
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.
As per wikipedia igneous rock derived from the latin word ignis meaning fire is one of the three main rock types the others being sedimentary and metamorphic igneous rock is formed through the cooling and solidification of magma or lava.
In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration.
