Marble stone is a metamorphic rock that forms when limestone is subjected to high pressure or heat and has a solid, cool and soft texture with various price lists per meter, square foot… In its pure form. marble is a white stone with a crystalline form and sugar, calcium carbonate (CaCO3).
Marble usually contains other minerals including quartz, graphite, pyrite and iron oxide. These marble minerals can be pink, brown, gray, green or any other color. Although true marble comes from limestone, there is also dolomitic marble, which is formed by the weathering of dolomite [CaMg(CO3)2].
Limestone, a marble pool, is formed when calcium carbonate precipitates from the water or when organic remains (shells, corals, shells) accumulate.
Marble is formed when limestone undergoes metamorphosis. Most of the time this occurs in the area of shifting tectonic plates, but some marbles occur when hot magma heats limestone or dolomite.
Heat or pressure hardens the calcite in the rock and changes its structure. Over time, the crystals grow and fuse with the rock in the form of ice and glitter.
Other minerals in the marble also change during metamorphism. For example, clay solidifies into mica and other silicates.
Marble is found all over the world, but half of its production is in four countries: Italy, China, Spain and India. Perhaps the most famous white marble comes from Carrara, Italy. Carrara marble was used by Michelangelo, Donatello and Canova for their sculptures.
The crystals found in marble have a stone-like surface and appearance, but there are other things that characterize the rock.
Marble is a strong, hard stone, although its primary mineral, calcite, has a Mohs hardness of only 3. Marble can be scratched by metal surfaces.
The color of the marble is light. Pure marble is white. Marble can be black with a lot of bituminous material. Most marble is gray, pink, brown, green, yellow or blue.
The marble vibrates when exposed to dilute hydrochloric acid.

Due to the nature of marble, it is found in large deposits around the world. This common, profitable rock can be mined in bulk.
Marble is mostly used in construction. Crushed marble is used for the construction of roads, building foundations and railway beds. Dimension stone is made by cutting marble into blocks or slabs. Amethyst is used to construct buildings, statues, paving stones and monuments.
The statue of Lincoln in the Lincoln Memorial is white Georgian marble, the base is pink Tennessee marble, and the exterior is Colorado marble. Marble is sensitive to acid rain and weathering, so it wears out over time.
White marble is ground to create “transparency,” a powder that is used to illuminate and brighten. Powdered marble can be used and can be used as a calcium supplement for the animal. Crushed or powdered marble is used in the chemical industry to neutralize acids, fill pellets and remove acid damage in water and soil.
The marble is heated to remove the carbon dioxide, leaving calcium oxide or lime. Lime is used in agriculture to reduce soil acidity.
Polished travertine is sometimes called marble. Travertine is a sedimentary rock. Polished travertine is sometimes called marble. Marble stone price per square footMarble stone texture seamless.
Marble stone price per square foot
According to HomeAdvisor, marble stone floors can cost anywhere from $40 to $100 per square foot, with an average price of $60 per square foot.
marble, limestone, or dolomite (i.e., a rock composed of calcium-magnesium carbonate) that has crystallized under the influence of heat, pressure, and aqueous solution. The market contains all the calcareous ornamental rocks that can be ground and some snakes (antique verd).
Petrographically, the marble is rich rather than thinly layered, a mosaic of calcite grains that show no signs of crystallization under the microscope.
It is broken by mint cracks that resemble the rhombohedral cleavage (fracture planes that intersect to form diamond shapes) of calcite. In very badly weathered rocks, grain lines are visible and may be stretched in one direction or cracked.

Many marbles are included in metamorphic rocks such as mica schists, phyllites, gneisses, and granulites, and are often found in older layers of the Earth’s crust that are deeply buried in highly folded regions and mountains.
The change from semi-precious stones to true marbles in temperate regions is common; in some cases, as in Carrara, Italy, and Bergen, Norway, the drying of the rock did not completely remove the coal structures.
Most of the white and gray marbles from Alabama, Georgia, and western New England, as well as the marble from Yule, Colorado, are recrystallized rocks, and many famous Greek and Italian marble statues from antiquity are still mined.
These are the Parina marble, the Pentelian marble from Attica, on which Phidias, Praxiteles and other Greek sculptors created their major works, and the snow-white Carrara marble used by Michelangelo and Antonio Canova with the best modern sculptors.
The exterior of the National Gallery of Art in Washington, D.C. is Tennessee marble, while the Lincoln Memorial features marble from Yule, Colorado.
Alabama (ceiling) and Georgia (Lincoln statue). Although natural marbles, such as those from Carrara, are pure, they contain other minerals, often a large part of the mass.
The most important are quartz in small rounded grains, flakes of colorless or yellowish mica (muscovite and phlogopite), dark graphite flakes, iron oxides and small pyrite crystals.
Many marbles contain other minerals, mainly lime or magnesium. Diopside is often white or light green; white surface tremolite and pale green actinolite also occur; feldspar can be a type of potassium but plagioclase (sodium to calcium rich) such as albite, labradorite or anorthite.
Scapolite, quartzite, vesuvianite, spinel, forsterite, periclase, brucite, talc, zoisite, wollastonite, chlorite, tourmaline, epidote, chondrodite, biotite, titanite, and apatite are all inclusion minerals. Pyrrhotite, sphalerite and chalcopyrite may also be present in small amounts.
These minerals represent impurities in the original limestone that reacted to new compounds during metamorphosis. Alumina represents a clay inclusion; Silicates obtain silica from quartz and clay; iron is obtained from limonite, hematite or feldspar in the original sedimentary rock.
Sometimes it is possible to see the original bed of platinum sediments according to the mineral bundles in the marble.
Silicate minerals, when abundant, may be marble-like; for example, it is green in the case of green pyroxenes and amphiboles; brown in garnet and vesuvianite; and yellower than epidote, chondrodite and titanite. Black and gray colors appear in the presence of fine graph scales.
The calc-silicate rock groups differ from the marble groups, forming nodules and spots, sometimes creating interesting decorative effects, but these rocks are very difficult to complete due to the large age difference between the minerals and the carbonate minerals.
Later, the physical and chemical breakdown of the beads resulted in a variety of beautiful colors and variations. Decomposition produces hematite, brown limonite, pale green talc, and especially green or yellow serpentine derived from forsterite and diopside, which are characteristic of ophiclites and green antiquities.
Earth movements break up the rocks and create a crater that is filled with calcite veins; the result is beautiful broken or split balls. Sometimes broken and rounded pieces are rolled with a marble stream under pressure.
The so-called onyx marbles are solid zones of calcite or aragonite that were deposited by cold solutions in caves and crevices and at the exits of springs.
Of course, it is not marble or onyx, because true onyx is a folded cascade composed mostly of carbon dioxide. Onyx marble was once “alabaster”, but alabaster is now called gypsum, a calcium sulfate rock.
These beads are brown or yellow due to iron oxide. Notable examples include the giallo antico (“old yellow marble”) of Italian antiques, the reddish-brown Siena marble of Tuscany, the large Mexican deposits of Tecali near Mexico City and El Marmol in California, and Algerian onyx marble. It was used in the buildings of Carthage and Rome and was also found near Oued-Abdallah in 1849.
Unrefined limestones of various colors and fossil remains are widely used for architectural purposes. Paleozoic rocks (251 million to 542 million years old) of Great Britain, for example, include “madrepore marbles” rich in fossilized rubies and “encrinital marbles” containing crinoid stems and arm plates with circular cross-section.
Shell sandstones from the Purbeck Beds in England and the Sussex Marble, both of Mesozoic age (251 million to 65.5 million years ago), contain many shells of freshwater snails embedded in blue, gray or green stone. It is popular with medieval artists and can be found in Westminster Abbey and other English churches.
Widely used are black sands containing a bituminous substance that emits an unpleasant odor when touched; The famous Belgian petit granite is a black marble containing crinoid stem plates derived from fossil echinoderms (invertebrate marine animals).
Marble stone texture seamless
Marble stone is used for buildings and monuments, interior decorations, sculptures, tabletops and novelty items largely because of its seamless texture.
Color and shape are their main characteristics. The abrasion resistance, the function of the combination between the grains, as well as the hardness of the component minerals are important for the floor and walking. Light transmission capacity is important for columnar marble, which creates its brightness by light entering from 12.7 to 38 mm (0.5 to 1.5 in) from where it is reflected onto the surface of deep-lying crystals.
Green marbles, colored marbles, onyx marbles, old plantations are used for interior decoration as well as modern. Sculptural marble, the most expensive type, must be pure white and have the same grain.
To maintain outdoor use, the marble should be smooth and free of cracks to prevent water from entering and discoloring the stone or cracking due to frost. It should not contain impurities such as pyrite that could be affected by contamination or weathering.
Calcite marbles are exposed to atmospheric moisture that is acidified with carbon dioxide, sulfur, and other gases that keep the surface smooth during weathering; but dolomitic limestone can weather and weather the sandstone surface to form dolomite crystals.
The main mineral in marble is calcite, and varying this mineral in hardness, light transmission and other properties in different ways has many useful results for the preparation of some marble.
Calcite crystals are two-sided – light is emitted in two directions, more light in one direction; boards prepared for applications where transparency is important are cut parallel to this direction. The bending of marble slabs is caused by the directional thermal expansion of calcite crystals when heated.
Explosives are rarely used in marble mining because of the danger of crushing the rock. In contrast, channel machines using galvanized steel bars cut about 5 cm (2 in) wide and several meters deep.
Where possible, joints of rock, cut in a manner that can be easily separated due to the expansion of friable minerals and minerals, are useful.
Marble blocks are characterized by joints and cuts that are separated by driving wedges into screw holes. Milling the boards is done using sets of parallel steel knives that move back and forth and are fed with sand and water.
Marble can be worked with carborundum discs and polished with finer types of abrasives. Despite the most careful mining and production methods, half of the marble is waste.
Some of them are made into chips for terrazzo floors and stucco wall treatments. In many areas, it is used for most of the important uses that are suitable for high-quality limestone.
Everyone knows that marble looks great and is probably one of the best investments a homeowner can make, but there are many other aspects of this natural stone that are worth learning about.
Marble has had a special place in the field of masonry and construction for thousands of years. We may have learned everything about it, but some facts are better than others. Here are five facts about marble and its various uses.
1. Some marbles are pebbles Geologically, marbles start out as pebbles. Tectonic and volcanic activity causes extreme heat and pressure that cause limestone to remineralize and change its molecular structure and shape.
Some exterior marbles quarried in Sinai are creamy yellow in color with a pattern set in gold. Since the geological process was interrupted in this part of the earth’s crust before it reached the surface, it is more correct to call this stone yellow marble. 2.
Some Egyptian pyramids covered with marble Thousands of years ago, many pyramids in Egypt had a white sheen. The first builders cut and polished white granite slabs for the large pyramids and beige marble for the smaller ones.
Marble blocks and columns were used to decorate Egyptian temples, but were later removed to build mosques during the Caliphate. For this reason, you can find symbols on the marble panels of old mosques outside of Cairo. 3.
Garden Activities Beyond Construction Marble is used to make stickers, paints, fine paper and even luxury iPhone cases. Marble powder is sometimes added to “Chinese clay”, a binder used to make pellets.
Marble powder also has one medicinal use: because its minerals have properties to reduce stomach acid, it is found in medicines such as Alka Seltzer. 4.
Michelangelo Fallen for the Marble Renaissance artists tried to improve marbles, but were amazed by the perfection of the works of the ancient Greeks and Romans.
Michelangelo thought that his ancestors were good at choosing marble for their sculptures because of the elegant appearance of the white stone.
But he did not know that these idols were painted with different colors but the characters disappeared. 5. Marble does not stop changing Even when it is cut, finished and loaded, marble does not stop being a metamorphic rock.
For homeowners, this means that their floors and walls can be involved in chemical reactions that change their appearance.
Acidic substances, minerals found in hard water, acid rain and extreme heat are some of the conditions that cause marble to change and change. The best way to prevent irreversible reactions in marble is to always apply a sealer.
