Granit Origin
Granite is a common and widely-occurring group of intrusive felsic igneous rocks that form at great depths and pressures under continents. The word granite comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a crystalline rock.
There are two theories for the origin of granite. The magmatic theory states that granite is derived by the crystal fractionation of magma. Thus granite bodies are the result of intrusion of liquid magma into the existing rocks. The granitization theory states that granite is formed in place by extreme metamorphism. There is evidence to support both theories, and both are useful to explain different observed features. The two may actually merge: as metamorphic conditions increase to the melting point of the metamorphosed granite, it will melt and become a liquid magma.

Granite Types and Colors
Based on the composition, the color and the make of the granite also varies there are various types of granite comprising of over hundreds of shades. Within India itself there are around 200 shades of granite available. To name a few -Tropical Green Paradiso, Kerala White, Pink and Grey Granite, Monumental red granite which is very coarse, Kashmir White, Tiger Skin, Bash Paradiso, Colombo Juparana, Sea Green, Turaiyur Blue, Hosur Gray, Raw Silk, Ruby Red, Fish Belly, Tumkur Pink, Sira Grey, Savan Rose, English Teak, Hasan Green Tiger Black, Chilly Red, Pista Green, Black Galaxy, Daisy Blue, Blue Pearl, Purplish Granite Porphyry, Mokalsar Green, Silver galaxy, Ivory Shine, Tan Brown, Steel gray, China Pink, Sea weed green, Spotty Black, Chilka Blue, Red Pearl, Spotty Ribbon Gneiss, Deep Pink Granite, American/ Cobra / Emerald Green
