Is Granite A Sedimentary Rock
The granite melts into lava then cools becoming igneous.
Is granite a sedimentary rock. Sedimentary igneous and metamorphic. The most important geological processes that lead to the creation of sedimentary rocks are erosion weathering dissolution precipitation and lithification. 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. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.
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. The sedimentary rock becomes metamorphic with heat and pressure. Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. Sedimentation is the collective name for processes that cause these particles to settle in place.
Sedimentary rocks may contain fossils of animals and plants trapped in the sediments as the rock was formed. In the rock cycle there are three different types of rocks. It forms from the slow crystallization of magma below earth s surface. Sedimentary rocks like this sandstone form layers.
Outcrops of granite tend to form tors domes or bornhardts and rounded massifs. Examples of sedimentary rock are. Generally the slower the molten rock cooled the larger. 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. Sedimentary rocks were originally sediments which were compacted under high pressure. 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 and igneous rocks began as something other than rock.
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. It erodes into sediment and then gets compressed into a sedimentary rock. Much of it was intruded during the precambrian age. It is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents.
