What we should know about Marble

.Marble is a metamorphose carbonate rock that has a distinct crystalline texture due to recrystallization under heat and pressure and it is mainly composed of calcite and dolomite minerals or a combination of both

.The difference in the appearance of marble and travertine is that the surface of travertine has holes, marble rarely has holes and porosity but it has fossils and light veins

?How marble stones are formed

Marble is a metamorphosed stone that is formed by the recrystallization of limestone, in such a way that over time and under pressure and heat, the texture and structure of limestone is transformed, recrystallized and a large, rough and veined calcite is formed

?Where are the marble mines located

In Iran, many mines have been identified and are being exploited. Of course, there are certainly many mines of marble in our country, Iran, which have not been identified or if they have been identified, they have not been exploited. Marble is produced and processed in a wide range of colors in Iran

.The total number of marble mines in the country is about 652. The largest share with 163 mines belongs to Isfahan province. Fars province with 76, Khorasan Razavi with 67 and Kurdistan with 51 mines are in the next ranks

.According to mines distribution on the map , the marble stone poles can be considered as the center, south, northeast and west of Iran

?What designs and colors does marble have

.This stone has chains called stylolite, which can be seen in the stone’s texture like a heart rhythm

Pure marble has white and shiny color. The light gray to black color is caused by carbonaceous materials. Green colors are usually produced by chlorite or other silicates. The pink and red color is due to the presence of very fine scattered particles of hematite or manganese carbonate, And the yellow and cream color is due to the presence of limonite

.Pietra Gray marble is grayish black background with white veins 

.Dehbid Spider marble has brown background 

.Dehbid Shayan marble stone has a cream colored background

.Galaxy marble has black color background

:Use of marble stone

Due to its calcareous nature , marble stones have very high water absorption. For this reason, they shouldn’t be used in places with a lot of moisture, such as restrooms, toilets, kitchens, and bathrooms. This stone is not resistant to natural factors such as rain, cold and heat and weathering like travertine and granites. Therefore, if marble stones are used in places that are exposed to cold and heat, they will have putrefaction and corrosion

In general, marbles are not a good choice for outdoor spaces, unless they are very thick which can prevent water penetration and corrosion of the stone, and also delay deep cracks, or if the surface doesn’t have abrasion As we mentioned before, this stone is the most ideal choice for indoor use, and on the other hand, the high variety of colors and the possibility of carving patterns on this stone and its abration have distinguished it from other stones. Marble can be processed by UV and special mastics which increases its capabilities and lifespan
