What is Granite and how is it formed?

Formation of granite can be explained by plate tectonics. Almost all granite forms at convergent plate boundaries where subduction is taking place. Subduction is the downward plunging of one plate under another. There are two steps involved in the formation of Granite. In the first step the subducting plate dives into the Earth’s mantle, heats up and begins to melt. This creates magma. Now when the magma rises it starts melting in the rock above it which further makes more magma. So when this magma gets cooler, it makes igneous rocks like diorite. In the second step, melting, subduction and magma formation will continue. Now when the magmas produced in this stage rise upwards, it will make part of the diorite that was produced in the first step to begin to melt. This, combined with melting of surrounding sedimentary and igneous rocks, makes magma which cools to become granite.

Types of Granite

Types of Granite and their Formation

Granite is an igneous rock made up of primarily quartz, feldspar, micas, amphiboles, and a mixture of additional trace minerals. It is formed through the cooling and solidification of magma or lava. Granite forms from the slow crystallization of magma below Earth’s surface. The two major types of igneous rock are extrusive and invasive. Extrusive rocks are formed from lava on the surface of the Earth, which is a magma that has erupted from the crust. Intrusive rocks are formed from magma, which cools and solidifies within the crust of the earth.

Gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of granite, or sedimentary rock. Gneiss displays distinct foliation, representing alternating layers composed of different minerals. Mineralogy, gneiss appears to contain quartz, feldspar, mica, chlorite and other minerals of clay. Some also contain larger crystals embedded in the rock matrix, most commonly garnet, topaz and beryl minerals.

What Are the Characteristics of Granite?

The characteristics of granite are as versatile as its colors. Granite characteristics include strength and toughness. This rare and elegant natural stone is one of the oldest, toughest and strongest stones in the world. Granite is a stunning natural stone with hundreds of color options and designs to choose from. It is a highly durable natural stone which is more resistant to the acids found in lemons, vinegars, and cleaning products which means most granite does not etch. Granite is stain resistant which means you can easily clean it with a piece of cloth if coffee or wine spills over it. Granite can withstand heat up to 1200 degrees Fahrenheit. Granite countertops will not melt or blister when exposed to heat. Granite is comprised of many different minerals that give each slab a unique and attractive appearance. Granite countertops are considered a low maintenance countertop surface. The risk of damaging a granite countertop is minimal. The range of colors that granite has to offer makes it a much sought after countertop material. Same granite yet different patterns and colors result from its origin and the absorption of minerals in it. Quartz, amphiboles, feldspar, potassium, and mica are responsible for imparting such lovely and distinguished colors to granite. Every mineral deposit makes granite different in color. Quartz makes granite pearly white whereas biotite makes it brown.

Reason and Advantages of Granite

The applications of granite are as expansive as its properties. Granite can be used both in interior and exterior projects with equal dynamisms. While interior projects may include countertops for bathroom or kitchen, exterior projects encompass constructions and building monuments or pavements. Below we have discussed a few reasons and advantages of granite for which people use it a lot.

High durability and value for money: Granite is one of the hardest materials on earth. It is durable and it really lasts long. It can be easily repaired, can be re-polished and it can withstand UV rays, heavy use and tough weather conditions. Resistant to scratching, cracking, and chipping; a properly installed, sealed granite countertop will look like new and most likely last your lifetime under normal use. It increases the value of the property due to its characteristic combination which makes it a value for money material and it has higher resale value, higher valuation.

Highly resistant to stains, heat and scratches: It ranks 7 on MOH’s hardness scale and is hard to scratch. Granite is stain resistant which means you can easily clean it with a piece of cloth if coffee or wine spills over it. It is also heat resistant as it is formed due to lava heat melting earth’s crust. Granite is also non porous which means less water resistant and stain resistant.

Hardest countertop material which is easy to maintain: Among the many options you have for natural stone countertops, granite is one of the easiest to maintain. It does not require any chemical washing and you just need simple sealer to maintain it. It is among the hardest countertop materials available and is not easily damaged. Warm water, mild dishwashing liquid and soft clean cloth is generally all that’s needed to maintain your granite countertop surface.

Granite maintenance and care

You might also want to ponder upon certain limitations of Granite, which are very few when compared with the positives:

Granite needs to be sealed regularly: The most common disadvantage of granite is that it needs to be periodically resealed in order to keep it properly protected. Properly sealing protects granite from stains and bacterial growth. Sealing is required once or twice a year to keep the stone looking and performing its best for a lifetime.

Porosity: Granite is less porous when compared to marble. Granite easily absorbs acidic substances, liquids and cosmetics, which can bring stains to its surface.

Disadvantages of Granite
Applications for Granite

Suggested Applications for Granite

Granite, in particular, is very strong because it formed under extreme pressure and heat. It is also heat resistant and virtually scratch-resistant, which makes it the ideal material for bathroom floors. Granite is also best for bathroom walls as advanced tools and techniques make it possible to cut granite into just about any shape you can imagine. Granite, gives you much more room to have fun with your design. Being a hard material, granite walls are very resistant to cracks and chips. Also, to clean granite shower walls, all you need to do is wipe them down.

Granite is also good for vanity countertops as they are exceptionally strong, offering superior protection against dents, scratches, and stains. They are also naturally resistant to heat and humidity, making them a good choice for the bathroom.

When we talk about bathroom flooring, the best part of having granite flooring in the living room is its durability. It will stand up excellently to things like pet claws or heavy foot traffic without as much as a scratch. It also requires very less maintenance and simple sweeping and occasional mopping should be sufficient to keep your floors looking gorgeous. Granite is also very resistant to erosion and can be used as wall covering. Due to its high toughness, this stone can withstand difficult weather conditions.

Granite adds glamour to your kitchen as well. Its countertops not only add an instant upscale appeal to your kitchen but give your home lasting value, making it a wise investment. It is also heat resistant material which makes it an ideal material to have in your kitchen tops. Placing hot pots or pans directly on your countertop is acceptable since granite can take the heat without being damaged or weakened. It is also stain resistance which means granite countertops won’t absorb liquids when they are properly sealed.
