Is Granite A Sedimentary Rock

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.

Is granite a sedimentary rock.

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. 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. Much of it was intruded during the precambrian age.

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. 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. 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.

Granite is not the kind of rock that would form into sandstone. Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands. 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 containing rock is widely distributed throughout the continental crust.
