Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble is commonly used for sculpture and as a building material. The many uses of marble used in monuments crushed stone cosmetics pharmaceuticals and more.

The taj mahal is one of the most beautiful and famous buildings in the world. It was built between 1632 and 1653 as a mausoleum for mumtaz mahal. 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.

Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques. Home rocks metamorphic rocks uses of marble. 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 under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. 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.

Marble is a granular metamorphic rock it is derived from limestone or dolomite and it consists of a mass of interlocking grains of calcite or the mineral dolomite. Form of it when limestone buried deep in the older layers of earth s crust is subjected to heat and pressure from thick layers of overlying sediments.
