Is Granite A Sedimentary Rock

It forms from the slow crystallization of magma below earth s surface.

Is granite a sedimentary rock.

Formally granite is a plutonic rock that is composed of between 10 to 50 quartz typically semi transparent white and 65 to 90 total feldspar typically a pinkish or white hue. But there has been a famous debate over the years because extreme metamorphosis of crustal sediments can produce melts of rocks that are also granite. It is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents. Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands.

Sandstone is a sedimentary rock that is worn away by dirt and dust rubbing against it in the wind. Generally the slower the molten rock cooled the larger. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

Much of it was intruded during the precambrian age. Granite is not the kind of rock that would form into sandstone. A rock with a similar composition and appearance as granite gneiss can form through long and intense metamorphism of sedimentary paragneiss or igneous rocks orthogneiss. In general terms granite is an igneous rock.
