What's the difference between an ordinary stone and a marble?
But the stone is generally refers to the small rock by rock body under external force and falling down, more dependent on the big rock surface, usually into a block or oval, the appearance of some rough, some smooth, firm texture, crisp. It can be used to make stone tools and collect stone mines.
In interior decoration, the TV table, window sill, indoor ground and so on are suitable for marble. Marble is a commodity name, not a petrological definition. Marble is a kind of natural building decorative stone, usually refers to the decorative function, can be processed into construction stone or handicraft of metamorphic or metamorphic carbonate rock. It is named after Cangshan Yunnan, Dali, China, which is made of stone with brilliant colors and patterns. Marble generally refers to marble, limestone, dolomite, and carbonate rocks formed by different alteration of skarn and marble. Marble is mainly used for processing all kinds of shaped materials, plates, as the walls of buildings, floors, platforms and columns, is precious materials inlaid furniture. Material used in monumental structures such as monuments, towers, statues, etc.. Marble can also be carved into arts and crafts, stationery, lamps, utensils and other practical works of art. Marble texture of soft, beautiful, solemn, elegant style, a large variety of colors, decorative luxury building is an ideal material, but also the traditional materials of art engraving.
Marble is mainly composed of calcite, limestone, serpentine and dolomite. Its main component is mainly calcium carbonate, accounting for more than 50%. As marble generally contains impurities, and calcium carbonate in the atmosphere by carbon dioxide, carbide, water vapor, but also easy to weathering and corrosion, and make the surface soon lose luster. Marble is relatively soft in nature, which is relative to granite.
Also called marble, marble is recrystallized limestone, as long as the component is CaCO3. Limestone softens at high temperatures and pressures and crystallizes to form marble when minerals change. The main component is calcium and dolomite, many colors, usually have a clear pattern, a lot of mineral particles. Mohs hardness between 2.5 to 5. Marble is a metamorphic rock formed in the crust by the action of high temperature and high pressure in the crust. The internal force of the crust changes the original rock mass, that is to say, the structure, structure and mineral composition of the rock have changed. New rocks formed by qualitative change are called metamorphic rocks.
