Granite is an igneous rock that is formed from magma.
Granite is formed when magma is cooled under the earth's crust.
It cools very slowly because it hardens under the earth's surface.
The granitization theory says that granite is formed through metamorphism of other igneous or sedimentary rock or metamorphic heat.
Its name came from a latin word, granum, which stands for grain because it has a grain or crystallized structure.
It is compose of quartz, mica, alkaline feldspar, and plagioclase feldspar.
Other minerals such as hornblende, magnetite, hematite, pyrite, zircon, garnet, and corundum make up the granite also.
The proportion of these minerals determines the kind of granite that is formed.
The A-Q-P diagram is used to classify granite rocks.
If there are more plagioclase feldspar, the granite is considered monzogranite.
The proportion of these minerals determines the color and texture of the granite.
It is available in various color such as pink, gray, and black.
Its impurities make the vein appearance on the granite.
The chemical component of granite includes silicon dioxide, aluminum oxide, potassium oxide, sodium oxide, calcium oxide, iron oxide, magnesium oxide, water, titanium dioxide, diphosphorus pentoxide, and manganese oxide.
Its structure has made it a strong and hard type of rock, which made it a popular material for construction use.
This is because the crystals within the granite have very little spaces among them.
Aside from its strength, it is also widely abundant on the earth's crust, which makes it readily available to the people.
Granite is usually found in Norway, Finland, Spain, Brazil, India, South Africa, and the United States.
Granite is also a source of natural radiation.
Granite has a small percentage of uranium in its composition.
Even so, studies have found that the radiation it emits is not hazardous to human beings.
Granite is manufactured as tiles for building construction.
Granite is considered more durable than marble because it can withstand extreme events such as acid rains.
Granite for interior decoration is usually polished ones because it is more appealing to the eye.
These are often used as kitchen countertops for instance.
It is also used in bathroom, floors, and walls.
Although granite is known for its durability, it still needs to be sealed and restored once or twice every year to prevent stains from appearing.
Granite is also preferred by many builders because it can withstand high level of pressure.
Aside from that, it weathers slowly.
This is so because granite is scratch resistant.
Granite is also heat resistant, which able it to give a cooling effect to anyone who touches it.
This characteristic makes the house more comfortable to stay in.
Scientific studies indeed confirm that granite has many positive attributes and characteristics.
These traits are the reason why it is perfect for building construction and design.
Granite, which comes from the deepest part of the volcanoes, is truly precious rocks that benefit the human society in their economic pursuits.
Granite is every person's friend in house construction.
It will never let you down.
