Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Unlike terrestrial materials meteorites have a crust formed by the high heat generated by atmospheric friction and they usually look blacker than surrounding rocks.

Because they look so much like common materials such as lava rocks or slag from a smelting plant it s easy to misidentify them. In the formation of marble metamorphism causes variable recrystallization of the original carbonate mineral grains which results in interlocking mosaic of carbonate crystals.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. A bluish marble looks exactly like the earth with some swirls of color white scattered along the surface. 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. Like other metamorphic rocks marble has no fossils and any layering that appears in it probably does not correspond to the original bedding of the precursor limestone.
