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.
Is granite a sedimentary rock.
Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.
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.
Outcrops of granite tend to form tors domes or bornhardts and rounded massifs.
It is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents.
Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock.
Much of it was intruded during the precambrian age.
Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands.
Granite containing rock is widely distributed throughout the continental crust.
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.
Sandstone is a sedimentary rock that is worn away by dirt and dust rubbing against it in the wind.
It forms from the slow crystallization of magma below earth s surface.
