Marble Dimension Stone: Marble cut into blocks and slabs of specific size is known as "dimension stone." Marble is developed from limestone which is a sedimentary rock. Both limestone and dolomite have a large concentration of calcium carbonate (CaCO3). Different types of rocks and minerals can form non-foliated metamorphic rocks. Metamorphic rocks form as the result of a solid-state transformation of preexisting rocks. As the favorite medium for Greek and Roman sculptors and architects (see classical sculpture), marble has become a cultural symbol of tradition and refined taste. Before metamorphism, the calcite in the limestone is often in the form of lithified fossil material and biological debris. Quartzite is a metamorphic sandstone. The change from limestones rich in fossils into true marbles in such metamorphic regions is a common phenomenon; occasionally, as at Carrara, Italy, and at Bergen, Norway, recrystallization of the rock has not completely obliterated the organic structures.

Slate Granite gneiss and biotite schist are strongly banded and foliated. The ensuing this rock is typically composed of an interlocking mosaic of carbonate crystals. Marble is a rock on account of metamorphism of sedimentary carbonate rocks, maximum normally limestone or dolomite rock. Contact metamorphism of the Leadville limestone created the Yule Marble. The intrusion heats the surrounding rock, making the low-temperature minerals unstable. Marble is made through the process of pressure and heat added to an existing rock. Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is a coarse-grained metamorphic rock that can be many colors, including pink, white, yellow, brown, green or black. Marble is a metamorphic rock that comes from metamorphosed limestone or dolomite. Marble is commonly used for sculpture and as a building material.

It takes high polish and is often used for sculpture and as building material. Often, the changes are even more spectacular, with new minerals formed, such as garnet, mica,and tourmaline(as seen in schist). The transformation of limestone into marble usually occurs at convergent plate boundaries where large areas of Earth's crust are exposed to the heat and pressure of regional metamorphism. Likewise, outdoor marble statues, gravestones, or other marble structures are damaged by acid rain. The Elgin Marbles are marble sculptures from the Parthenon in Athens that are on display in the British Museum. metamorphic rock made almost entirely of quartz, for which the protolith was quartz arenite.

Recrystallization is what marks the separation between limestone and marble. carve, and that makes it useful for producing sculptures and ornamental objects. A related rock, dolomitic marble, is produced when dolostone is subjected to heat and pressure. Soapstone is an unusual type of rock which is formed when mineral talc, which is rich in magnesium is transformed into a solid, hard rock. Marble is among the non-foliated metamorphic rocks produced from the metamorphism of dolostone or limestone. This preference has to do with its softness, which made it easier to carve, relative isotropy and homogeneity, and a relative resistance to shattering. The main agents of metamorphism (which means “to change”) are heat, pressure, and chemically active fluids. [Image will be uploaded soon] Types of Metamorphic Rocks.
