The type of internal igneous rock is called granite, which has medium to large grains; granite stone is made of quartz and mica, feldspar, and other things.
The color of granite stone depends on the mineral and chemistry of the stone and variable colors such as pink, light gray, gray, black, and it is seen in nature.
Granite stone is made from cold molten masses called magma. Granite with a set weight of 2758 kg per cubic meter is one of the hardest and most resistant stones. Granite stone is more robust than marble and travertine, and its polished and shiny surface is more preserved. Granite is the most common stone that is widely used in the construction industry.
Granites are more resistant to limestone and have higher strength; for this reason, it is mainly used in busy places such as paving streets and office and commercial buildings and subway stations, and we should know that the use of granite for indoor spaces such as kitchen counters, building stairs, and even single paving Are also unobstructed. Granite stone can also be a good choice for the facade of buildings, but it should be borne in mind that scoping the stone was not neglected.
Granite stones for building facades, paving, cabinets, stairs, and other things are used. Granite is the best choice for the stairs of buildings. The building’s stairs are worn and polluted due to heavy traffic, so they should use a stone such as granite for them that has high strength and durability. The best places to use granite are parking spaces, courtyard floors, open kitchens and stairwells, and generally busy floors.
The best perspective on the stone is its cleaned state, which shows the excellence of the tone and the impression of its gems. Stone is regularly utilized for deck and divider outlines because of its exceptional style and brilliance.
There are a lot of mines in the country of Iran from which granite stones of different colors are extracted. Granite stone is one of the most well-known and familiar building materials, and this stone has been used in the interior space and exterior space of buildings for thousands of years. Most granites are hard and thus become durable building material. They are impervious to water entrance and affect and endure mechanical conditions well.
Iran likewise has different granite mines, the most famous of Mashhad pearl granite, Nehbandan granite, Birjand green lettuce granite, Birjand forest green, Khorram Dareh granite, turquoise granite, Hamedan cotton flower granite.
Granites are generally mined and bought in Central Asian nations like India, China, and Vietnam. Obviously, it ought to be noticed that Brazil also shows itself strongly in the supply of beautiful and unique granites in the market, and almost the most beautiful granites belong to this country. The price of Iranian granite stone and foreign granite depends on several factors. Also, its most significant boundaries are thickness, size, and preparation.
Granite ledges are made of unadulterated stone found in nature. The stone is cut and smoothed with sharp edges. It is offered in the form of a uniform tile or granite stone, and then it is polished and prepared for sale.
On the other hand, quartzite rocks are formed by crushing quartzite rocks to which pigments and resins (what’s more, a mix of synthetic compounds called fasteners) are added. Of course, most of this composition (about 92 to 94%) is made of quartzite rock. But if you need a counter that is all stone, you can choose granite.
Although granite stone has its beauty, it also has its weaknesses. This stone must be insulated during installation and installed by a trusted person. Quartzite is not as difficult to install as granite and does not require much care.
Quartzite starts at $ 80 per square foot and eventually goes up to $ 140 with installation costs. Granite starts at $ 80 per square foot and can go up to $ 225.
Counters are made of natural stone, which includes granite and sandstone, easily stained. Quartzite does not get dirty quickly, and because it is made of other materials, it does not have pores like granite and does not get dirty inside and does not absorb germs and bacteria. Quartzite is easy to maintain and clean. Granite stone may crack more than quartzite.
Granite is made out of the primary minerals, which are: quartz and plagioclase and potassium and feldspar and other dim like minerals. The measure of these minerals in stone decides the name of granite. Other minerals such as pyrite, hematite, mannite, and ilmenite are sometimes found in granite rocks.
In the following, we will describe to you the granites that have been identified with other names due to the presence of more or less percentage of minerals:
Aplite: This type of granite is composed only of quartz and feldspar, and there may be a tiny amount of mafic minerals.
Pegmatite granite: This type of granite has a coarse grain texture.
Granophyre Granite: This type of granite has fine grains of crystals that are made of quartz and feldspar that these fine grains have grown inside and formed type granite. Of course, it must be said that some granites may be metallic minerals such as mercury, manganese, magnetite, copper, gold, and silver.
As we have said before, granite’s texture is granular, and these grains are spread from medium to large on the surface of the granite and are usually semi-shaped. Coarse grains of potassium feldspar precious stones are found in rocks called porphyry surfaces.
In some granites, magnificent minerals such as apatite and sphene are seen in very small sizes. Of course, there is another category for the texture of granites, which is called block, mass, and rubble. One of the most common textures in granites is its granular texture, which makes this texture fine to large grains. It can be seen in ceramics.
The Green Granite Group started its operation in 1985 from the city of Birjand, South Khorasan in eastern Iran. The unique climate in this region (Birjand, South Khorasan) gives us the opportunity to have mining operation all year round.
