Marble is a metamorphosed limestone that is considered as a decorative stone. Marble has special characteristics and is used in the construction of stone artifacts and buildings. Marble has more relative weight and resistance due to less pores than travertine, but their resistance and weight is less than granites. Marble stone is extracted in many mines in Iran, which has caused marble to be available in the market with a reasonable price and a lot of variety.
Marble has a wide variety of colors and is extracted in all colors of cream, white, green, pink, red, brown, gray, black, etc. This variety of colors has caused this stone to be widely used in different parts.
How marble is formed
Marble is one of the sedimentary carbonate rocks and it is created from the minerals kelist, calcium carbonate and magnesium carbonate. These compounds are formed in the marine to semi-marine sedimentary environment and after some time they gain sufficient density and resistance. Other secondary minerals are involved in the formation of marble stones, and these secondary materials have caused the appearance of various colors in marble stones.
The process of transformation is the distinguishing feature of marbles and limestones that marbles undergo fractures and cracks during pressures and displacements in different directions.
Fractures in the carbonate stone cause this stone to become marble, which creates empty spaces on the surface of the stone, which are filled secondarily and gradually by different materials.
Silica (quartz), clay and calcite are among the most important materials that fill these empty spaces, but the most important thing is the effect that these materials have on the strength and durability of the stone. For example, silica makes marble resistant to scratching, but materials such as clays reduce the overall resistance of these stones.
Specifications and characteristics of marble stone
Marble is a decorative stone, that’s why it has a finer structure than other stones, that’s why it is not correct to compare the hardness and resistance of this stone with granite stones. The hardness of this stone is the reason for the desirable polishing of this stone. The lack of pores in this stone has increased the resistance of marble. Marble is only resistant to the extent that it is a decorative stone, not to the extent of a building stone, and this stone should not be expected to withstand weather conditions.
The best marble stone
Marble has a wide variety and it is not possible to choose one of them as the best, but Dehbid Chamorghi marble, Dehbid Shayan marble, Dehbid Arin marble, Dehbid Zare marble, Hersin marble, Khoy marble and Persian Silk marble, as well as Lashter marble, are of better quality than They have other marble stones.
Advantages and disadvantages of marble
Among the advantages of marble stone, the following can be mentioned:
- Eye-pleasing and variety of color and design of marble stone
- Uniform surface compared to travertine stones
- The presence of various mines inside the country
- The price is right
- Resistance to alkaline conditions
- Little water absorption
Among the disadvantages of marble, the following can be mentioned:
- Corrosion and erosion if exposed to moisture after some time
- Lack of scratch resistance in some marbles
- Freezing and breaking of outer layers in some marbles
- Lack of resistance to acid rain and detergents
Applications of marble stone
- Table top in front of the sofa
- stone vase
- iPhone stand
- Elevator floor stone
- Cabinet plate
- Covering the floor or the wall in the form of book match and form match designs

Marble has a wide variety and can be extracted in most parts of Iran, but it is mostly extracted in the mines of Yazd, Central, Kerman, Fars and Lorestan.
European countries such as Italy, Ireland, Spain, Greece, Russia, Romania, Sweden and Germany have also mined this stone. Asian countries, like India and China, are among the other prominent marble miners in the world. The United States of America is also a good producer of marble. Italy, China, India and Spain are the main producers of marble.
Variation in the type and density of marble stones has caused various processing to be done on these stones. For example, Lashtar marble can be processed in various ways, and this has led to various uses of this stone.
To prevent stone crushing and increase stone strength during stone cutting, glue and net are used behind marble stones.
They use epoxy, resin and UV materials to cover the cracks on the surface of this stone. These materials prevent the penetration of water and stains on the surface of the stone.
Processing of marble stones is done in different sizes and thicknesses such as tiles, longitudinal, small pieces and slabs.
The price of marble
There are many factors influencing the price of marble stone and it is impossible to consider an exact price for this stone. The price of marble stones with fewer layers, such as Dehbid marble, is higher than marble with many veins. In other words, the purer and more uniform the stone is and the less impurities it has, the higher the price of the stone.
The size and thickness of the stone are other factors affecting the price, that’s why the price of marble tile is lower than its slab.
One of the other factors affecting the price of Gadopai Coop marble is that the more the processing with stones with larger cuts, the higher the price.
In general, the type of cutting machine, the required processing, the type of consumables and polishers, the type of finish, as well as the distance from the quarry, the uniformity and homogeneity of the stone, the size and height of the stone are factors that affect the price of marble.
Comparison of marble and marble
One of the differences between marble and marble is the way they are formed, both of these stones are formed as a result of the transformation of limestone, and the only difference between them is that marble needs more time to transform.
The texture of these two types of stones is another difference between these two types of stones that can be mentioned. Marble has an interlocking texture. The purest type of marble is very similar to white marble.
Comparison of marble and travertine
Marble is one of the most similar stones to travertine and the only way to distinguish between these two stones is that marble has less voids than travertine.

Types of marble
Various quarries have mined marble, which produce and extract marble stones with different structures, designs, and colors.
In the structure of marble stones, we see differences in veins, material, color, size and thickness. For example, Dehbid Zare marble has beautiful veins like deer horns, and Salsali marble has veins in the shape of a heartbeat.
