Is Granite A Sedimentary Rocks

It is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents. 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. The most important geological processes that lead to the creation of sedimentary rocks are erosion weathering dissolution precipitation and lithification.

Granite belongs to the intrusive category of igneous rock which means it formed below the earth s surface as magma slowly cooled and crystallized.

Is granite a sedimentary rocks.

They are later known as basement rocks. Granite river rocks can have a speckled or banded appearance due to the coarse grains of minerals usually quartz and feldspar that form the granite composite. 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. In areas where earth s surface is covered with sedimentary rocks granites metamorphosed granites or closely related rocks are usually present beneath the sedimentary cover.

Granite is not the kind of rock that would form into sandstone. Granite is an example of a felsic intrusive rock while gabbro and diabase are examples of mafic intrusive rocks. Sedimentary rocks are formed on or near the earth s surface in contrast to metamorphic and igneous rocks which are formed deep within the earth. Under sedimentary rocks granites metamorphosed granites or related rocks are usually below this cover.

Outcrops of granite tend to form tors domes or bornhardts and rounded massifs. If the granite is exposed on the earth s surface it is caused by the rise of granite rocks and the erosion of the sedimentary rocks above it. Granite containing rock is widely distributed throughout the continental crust. Much of it was intruded during the precambrian age.

Definitions used for granite often lead to communication. Sandstone is a sedimentary rock that is worn away by dirt and dust rubbing against it in the wind. In general terms granite is an igneous rock. Sedimentary rocks are formed by the gradual consolidation of organic or inorganic solid fragments carried by suspended in or dropped by wind water or ice and deposited horizontally in layers.

Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands. If they are today exposed at the surface the only way that could happen is if the granite rocks were uplifted and the overlying sedimentary rocks were eroded.
