Which rock is most likely marble?
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
Why is marble A metamorphic rock?
Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.
Where is marble rock from?
Marble forms when limestone experiences metamorphism. Usually, this happens at a convergent tectonic plate boundary, but some marble forms when hot magma heats limestone or dolomite. The heat or pressure recrystallizes calcite in the rock, changing its texture.
How is marble stone made?
Where is marble rock found?
Marble can be found all over the world, but the four countries where it is most prevalent are Italy, Spain, India, and China. The most prestigious famous white marble comes from Carrara, Italy.
What is a marble stone?
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. Commercially, it includes all decorative calcium-rich rocks that can be polished, as well as certain serpentines (verd antiques).
What is made of marble?
Slabs and blocks of marble are used for stair treads, floor tiles, facing stone, cemetery stones, window sills, ashlars, sculptures, benches, paving stones and many other uses.

What minerals are in marble?
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. 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.
What are the special features of marble?
Characteristics Of Marbles. Marble is a stone with a firm crystalline structure and slight porosity. Due to its structure, marble can be polished to improve its shine and is thus a common and attractive stone for building applications. The restricted marble porosity, mainly when refined, makes it less susceptible to water damage.
What is the formation of marble?
Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. 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.
