Today, ornamental stones are widely used in the construction industry and in the construction of elements and sculptures around the world. Among the most famous ornamental stones are granite, marble and marble.

Each of these stones has a wide variety of designs, colors and mechanical properties. Meanwhile, the unique beauty of most marble stones has made them very popular in many countries. In this article, the sources of marble formation and the special conditions for the formation of this type of rocks are examined.

Formation of marble

Marble is originally composed of calcium carbonate along with other minerals such as various oxides, clay, mica and quartz at critical temperatures and pressures. Depending on the ingredients and the percentage of calcite, the type of marble and its physical properties will vary.

In this way, the marble stones that have been known so far have different colors and designs with different mechanical properties. In the continuation of this article, useful information about the formation points of marble and the characteristics of each region will be provided to you.

In which countries is marble formation most prevalent?

Marble is not limited to a specific geographical area, and in large areas of the earth's surface we see the extraction of various species of this ornamental stone. China, Turkey, Iran, Italy and Spain are the largest holders of marble resources in the world, according to statistics compiled each year on marble quarry in various countries.

Among the marble quarries are countries such as Egypt, Oman, France, Portugal, Indonesia, the Philippines and Mexico. Some countries have lower exports, despite the lack of facilities and machinery, despite the rich resources of marble. Countries such as China allocate significant volumes of extracted marble for domestic consumption.

Despite its vast marble resources, China is one of the largest importers of marble in the world. Italy is one of the oldest marble quarries. These stones can be seen in the facades of many historical monuments in this country. The Carrara and Monte Altissimo quarries are among the most important quarries in Italy.

What are the characteristics of a marble formation to make marbles?

Dolomite, calcite, and aragonite are the three main and key components of marbles. What causes the variety in the color and design of marbles is the impurities associated with these materials. The results of previous research into marble have shown that gemstones are often found among gneiss and mica schist.

In fact, marble stones should be found in the oldest part of the earth's crust. Although the conditions for the formation of different types of marbles are somewhat different, all of these rocks are formed under two factors: temperature and pressure over a long period of time.

In addition to impurities in dolomite or calcite, the intensity of temperature and pressure and the time it takes to form these rocks will affect the physical and mechanical properties of marbles.

For example, the Italian Carrara marble was formed over 200 million years, the Makranaya marble of Rajasthan 150 million years ago, and the Spanish Crema Marfil after 75 million years. This is why

natural marble has become a unique product.

Why the Harsin Sardar marble quarry is so popular?

Among the most important factors that lead to the popularity of ornamental stones, we can mention its strength, beauty in design and color, price and abundance. Resistance to opacity of the marble surface in the face of environmental factors is another excellent feature of marble. The price of marbles will not be unaffected by their popularity.

On the other hand, various factors such as the abundance of stone, the distance from the quarry and the quality of the stone will cause a difference in the price of these stones. Among the marble stones available in Iran, the stones extracted from the Harsin Sardar quarry have attracted the attention of many consumers. Harsin Sardar marble quarries have a good quality compared to many similar stones.

This quality is interesting in contrast to the reasonable price set for these stones. Excellent mechanical properties and high resistance to environmental destructive factors such as acid rain, have caused these stones to be used as facades of buildings and paving stones.

 Conclusion

There are several things to keep in mind when choosing and buying marble or any decorative stone. Interior designers and architects consider factors such as geographical area, weather conditions, the cost of the stone, and the level of harmony between the design and the color of the marble and other components of the decoration to choose the right marble.

Finally, by putting the conditions together, you can choose the right stone. Marble rocks on the planet's surface have a wide variety. Meanwhile, the geographical region of Iran has the most valuable marble quarries in Iran. Therefore, buyers in this field have a wide range of choices.
