Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite. Metamorphism causes variable re-crystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.
Marble sculptors must be careful when handling their materials, as the stone can absorb skin oils and develop yellow or brown stains. While more resistant than limestone it is subject to attack by weak acids, and so performs poorly in outdoor environments subject to acid rain .
Monolith with bull, fox, and crane in low relief at Göbekli Tepe. The density of most stone is between 2 and 3 tons per cubic meter. Basalt weighs about 2.8 to 3.0 tons per cubic meter; granite averages about 2.75 metric tons per cubic meter; limestone, 2.7 metric tons per cubic meter; sandstone or marble, 2.5 tons per cubic meter.

Marble has been the preferred stone for sculptors in the European tradition ever since the time of classical Greece. It is available in a wide variety of colors, from white through pink and red to grey and black. [3] The hardest stone frequently carved is granite, at about 8 on the Mohs scale. It is the most durable of sculptural stones and ...

It was among the first types of Cycladic "island marble" to be used. It is the largest-grained marble which was used in ancient times. [3] It was already suggested by Richard Lepsius in 1890 that Naxian marble was used for the creation of ancient roof tiles at Olympia and on the Athenian Acropolis, [4] which subsequent research affirmed.
