Granite

Granite is the most commonly found igneous rock on the earth’s surface. As its name shows, granite comes from the word ‘granum,’ which means grain. An igneous rock with a light-color and can easily be seen through the naked eye due to its large grains is known as granite. The word igneous is derived from a Latin word ignis, which means fire.
The magma, which is a hot liquid under the earth’s surface, is the agent that forms granite. Therefore it is known as Igneous or magmatic rock.

Some granite components include minerals, a little amount of mica, quartz, amphiboles, and feldspar. Granites are of plutonic origin. The color of granite is due to the presence of various minerals. If we view a granite rock carefully, then grains of pink, red, white, or white color is clearly visible. We can recognize it in our home. It’s used to make paving stones, stairs, floor tiles, cemetery monuments, etc. Further, several granite mountains in different countries are famous attractions.

Some of them include Georgia, South Dakota, Pikes Peak, Stone Mountain White Mountains, New Hemisphere, etc. It is a firm, compact granular structure. Granite is commonly used due to its exceptional features like durability, waterproof, antimicrobial, and stain-protection. Most granite remains deeper within the crust at a depth of more than 1.5 km to about 50km. The areas where granites are found abundantly are Finland, Norway, Sweden, northern Portugal in Chaves and Vila Pouca de Aguiar, Spain, and India.

The process of granite formation:

Magmas crystallize to form granites. These crust of rocks have a felsic composition and were formed after cooling molten rocks. The duration of cooling determined the size of the granite crust. Eutectic point is a period when the temperature is minimum in a cotectic curve. When magma reaches, this pointed granite is formed. Low degrees of partial melting, as well as igneous differentiation, makes magma to evolve to the eutectic point. 

The substance rich in potassium, namely feldspar and quartz(SiO2), are said to be the primary components of granite. This is because of fractional crystallization, which leads to a melt in titanium, iron, magnesium, sodium, and calcium, yet enhances melt in potassium and silicon. Another necessary process of the granite formation is studied, namely Granitization.

India is an excellent place with precious stones available and best known for several traditional stones. Not only granite, but it also contains a variety of marbles, sandstone, slate, quartzite, and also limestone in several states of India. Indian stone industry is highly spread, and some well-known granite manufacturing industries remain in several states like Rajasthan, Odisha, Tamilnadu, Madhya Pradesh, Chhattisgarh, and Karnataka.
 
Indian granites are available with mesmerizing patterns and colors, which are best to renovate your home or office. Annually about 200 varieties of granites are exported to different regions of the world. Granites in India are excellent for interior and exterior design and give your home an elegant look. Though these are magnificent, their durability and waterproof nature force you to choose from other precious stones. Several types of granites are seen in India. Here we discussed granites according to their variety of colors.
