Marble is known from the Greek root of marmoros, the brilliant brand and the commercial brand of onix. Marble is a limestone type. The stubbornness of these rocks is very high and they are as elastic as possible. These rocks have different minerals and colors, and their main features include beautiful colors and fine luster. For decades, it has been used in building. These types of rocks are especially applicable in decoration, stairs, interior, column and floor. Marble rocks are used as unique materials in decorating large buildings and sculptures. In the last 15 to 20 years, due to the increasing growth of various industries, decorative stones and precious stones did not meet their needs. Nowadays a lot of sabo services are available for this type of rock.

Other types of marble gems are green stones that are used in Iran more often in religious places. In the presence of some dolomi in lime, dolomitic magnesium is blended with other materials and creates marble green. Marble rocks are resistant to adverse conditions, including heat and cold, and sunlight and rain. The marble rocks are derived from the conversion of limestone. The most important mineral that is called calcite is called. When limestone has been exposed for a long time under high pressure and heat, it is transformed and eventually turned into marble. There are also marble and stone travertine in places where there are hot springs.

Some types of marble contain 99% calcium carbonate; the main ingredient is calcium carbonate rock. The pure white marble is the most important and best mined in the Rostam Bam and Qorveh of Sanandaj, as well as in Italy. The best marble mines in the world are in Iran and Italy, which is superior to Italy in terms of color variation. The reason for the variety of colors is the presence of iron, aluminum, magnesium and the like. If there is anhydrous iron oxide, its color is brown or yellow, its color is red or pink due to the presence of dehydrated or dehydrated iron oxide, such as pigeon iron ore in West Azarbaijan province, and if it contains manganese and materials They are black, brown, gray or black. Some marbles have streaks, some are striped, and some are spotty or curly. Due to the metamorphism of metamorphic deposits, they are caused by metamorphism. The economic significance of the gems that make up the metamorphic deposits before the transformation stage is low. Smaller calcareous limestone stones, which are less economically important, are converted into marble deposits of high economic significance, due to regional variation and sometimes due to the proximity of metamorphism.

The hardness of marble stones is 3 to 4, although it’s not hard to say that marbles made of quartz are more difficult to calcite marbles.
