Granite is an igneous rock and is formed from magma. Granitic magma has many potential origins but it must intrude other rocks. Most granite intrusions are emplaced at depth within the crust, usually greater than 1.5 kilometres and up to 50 km depth within thick continental crust. The origin of granite is contentious and has led to varied schemes of classification. Classification schemes are regional and include French, British, and American systems.

Granite grinder is a common and widely occurring type of intrusive, felsic, igneous rock. Granites usually have a medium to coarse grained texture. Occasionally some individual crystals (phenocrysts) are larger than the groundmass in which case the texture is known as porphyritic. A granitic rock with a porphyritic texture is sometimes known as a porphyry. Granites can be pink to gray in color, depending on their chemistry and mineralogy. By definition, granite has a color index (i.e. the percentage of the rock made up of dark minerals) of less than 25%. Outcrops of granite tend to form tors, and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite is usually found in the continental plates of the Earths Crust.

Uses of Granite:

The Red Pyramid of Egypt (c.26th century BC), named for the light crimson hue of its exposed granite surfaces, is the third largest of Egyptian pyramids. Menkaure's Pyramid, likely dating to the same era, was constructed of limestone and granite blocks. The Great Pyramid of Giza (c.2580 BC) contains a huge granite sarcophagus fashioned of "Red Aswan Granite." The mostly ruined Black Pyramid dating from the reign of Amenemhat III once had a polished granite pyramidion or capstone, now on display in the main hall of the Egyptian Museum in Cairo (see Dahshur). Other uses in Ancient Egypt include columns, door lintels, sills, jambs, and wall and floor veneer.[15] How the Egyptians worked the solid granite is still a matter of debate. Dr. Patrick Hunt[16] has postulated that the Egyptians used emery shown to have higher hardness on the Mohs scale.

Granite mill is a kind of igneous rock and is shaped from magma. Granitic magma has some latent origins but it must intrude other rocks. In general, granite intrusions are placed in the crust, and located about 1.5 to 50km depth within thick continental crust. The nature of granite is controversial that emerge a lot of classification. These classifications are territorial; French, British, and American systems are included.

Granite belongs to a common type of intrusive, felsic, igneous rock. Granites generally have a medium, and its texture is coarse and grained. Sometimes individual crystals (phenocrysts) are larger than the groundmass due to the porphyritic texture. Porphyry is a granitic rock with a porphyritic texture. Granites can be colored in pink and gray owing to their chemistry and mineralogy. Granite possess less than 25% color index (i.e. the percentage of the rock comprised dark minerals). Tors and rounded massifs are easily formed by outcrops of granite. Granites appear in circular depressions surrounded by some hills at sometime, which shaped by the metamorphic aureole or hornfels and is often found in the continental plates of the Earths Crust.
