Is granite a igneous sedimentary or metamorphic rock.

The rock cycle is a continuous process describing the transformation of the rocks through various stages through their lifetime. To aid in their study of the earth geologists group rocks into three categories based on their origin. Igneous rocks are molten rocks expelled as lava that has cooled and become solid. In the rock cycle there are three different types of rocks.

The granite melts into lava then cools becoming igneous. The rock cycle simply moves from the igneous to metamorphic to sedimentary rocks and the process repeats itself over and over. Gray or light red. Sedimentary igneous and metamorphic.

About 27 000 years ago lava flowed on top of the navajo sandstone forming black ropey basalt in snow canyon state park washington county. Sedimentary and igneous rocks began as something other than rock. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below earth s surface.

Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks. Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. Sedimentary rocks were originally sediments which were compacted under high pressure. Examples of igneous rocks.

Igneous sedimentary and metamorphic. It is distinguished from granite because it does not contain quartz. Composed of feldspar and quartz. Each category is then further subdivided.

Metamorphic rocks on the other hand are transformed rocks as a result of exposure to extreme heat and pressure beneath the earth s mantle. Partial melt granitic type rocks are granitic gneiss which is a metamorphic rock. Even the granites that form via metamorphism of sediments are igneous because they pass through a melting stage. Sedimentary rocks are generally formed by matter that has settled beneath lakes and ocean floors.

It consists of calcium plagioclase pyroxene olivine hornblende and hypersthene. It erodes into sediment and then gets compressed into a sedimentary 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. The existing rock type which undergoes a change is referred to as the protolith.

The sedimentary rock becomes metamorphic with heat and pressure.
