Is marble a rock or mineral.

Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. Marble marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures.

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.

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. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. Marble is a metamorphic rock that comes from metamorphosed limestone or dolomite. 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.

Limestone is mostly calcite or calcium carbonate caco 3 dolomite camg co 3 2 is related to limestone but is rich in magnesium. There is a lot of variation in the color and texture of marble.
