Is Granite Sedimentary

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

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. It erodes into sediment and then gets compressed into a sedimentary rock. It forms from the slow crystallization of magma below earth s surface. Sedimentary rocks unlike the igneous rock granite form on both the earth s surface and underwater.

As an igneous rock granite is formed under very high heat and has a crystalline structure instead of a layered structure like sedimentary rock. M type mantle granites are rarer and are thought to have evolved directly from deeper melts in the mantle. 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. Essentially they are comprised of layer upon layer of sediment easy to remember sediment sedimentary build up over time.

Students of granites classify them in three or four categories. Sedimentary rock formation lacks the heat and pressure that created the igneous rock. Granite is an example of a felsic intrusive rock while gabbro and diabase are examples of mafic intrusive rocks. 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.

The granite melts into lava then cools becoming igneous. Strictly speaking granite is an. 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. 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.

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. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. 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.
