Is Granite A Sedimentary Rock

Sedimentary rocks may contain fossils of animals and plants trapped in the sediments as the rock was formed.

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. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock. Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands. Generally the slower the molten rock cooled the larger.

Sedimentary and igneous rocks began as something other than rock. Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. 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. 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.

Examples of sedimentary rock are. Sedimentary igneous and metamorphic. The sedimentary rock becomes metamorphic with heat and pressure. The most important geological processes that lead to the creation of sedimentary rocks are erosion weathering dissolution precipitation and lithification.

Much of it was intruded during the precambrian age. Outcrops of granite tend to form tors domes or bornhardts and rounded massifs. In the rock cycle there are three different types of rocks. Sedimentation is the collective name for processes that cause these particles to settle in place.

Sedimentary rocks were originally sediments which were compacted under high pressure. The granite melts into lava then cools becoming igneous. It erodes into sediment and then gets compressed into a sedimentary rock. It forms from the slow crystallization of magma below earth s surface.

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. It is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents. Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the earth s surface. Sedimentary rocks like this sandstone form layers.
