Is Granite Sedimentary

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.

Is granite sedimentary.

Essentially they are comprised of layer upon layer of sediment easy to remember sediment sedimentary build up over time. However in the dimension stone trade the word granite is used for any feldspar bearing rock with interlocking crystals that are large enough to be seen with the unaided eye. It forms from the slow crystallization of magma below earth s surface. Tile made from it is quite dense with a strength similar to porcelain says dave gobis executive director of the ceramic tile education foundation.

As an igneous rock granite is formed under very high heat and has a crystalline structure instead of a layered structure like sedimentary rock. The granite melts into lava then cools becoming igneous. Sedimentary rocks unlike the igneous rock granite form on both the earth s surface and underwater. It erodes into sediment and then gets compressed into a sedimentary rock.

Strictly speaking granite is an. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock generally the slower the molten rock cooled the larger it s mineral crystals with k feldspar megacrysts forming in special circumstances greater than 5cm. The sedimentary rock becomes metamorphic with heat and pressure. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline 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. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Sedimentary rock formation lacks the heat and pressure that created the igneous rock. Students of granites classify them in three or four categories.

I type igneous granites appear to arise from the melting of preexisting igneous rocks s type sedimentary granites from melted sedimentary rocks or their metamorphic equivalents in both cases. M type mantle granites are rarer and are thought to have evolved directly from deeper melts in the mantle. The definition of granite varies a geologist might define granite as a coarse grained quartz and feldspar bearing igneous rock that is made up entirely of crystals.
