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.

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. It is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents. Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. The sedimentary rock becomes metamorphic with heat and pressure.

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. It forms from the slow crystallization of magma below earth s surface. Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands. 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.

Generally the slower the molten rock cooled the larger. The particles that form a sedimentary rock are called sediment. Sedimentary rocks like this sandstone form layers. Sedimentary igneous and metamorphic.

It erodes into sediment and then gets compressed into a sedimentary rock. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Granite containing rock is widely distributed throughout the continental crust. The most important geological processes that lead to the creation of sedimentary rocks are erosion weathering dissolution precipitation and lithification.

Sedimentary rocks were originally sediments which were compacted under high pressure. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock. 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. Sedimentary and igneous rocks began as something other than rock.

Examples of sedimentary rock are. In the rock cycle there are three different types of rocks. Much of it was intruded during the precambrian age. Sedimentation is the collective name for processes that cause these particles to settle in place.
