Is granite an example of a metamorphic rock.

Examples of metamorphic rocks. Igneous rocks are formed through the cooling and solidification of magma or lava. Gneiss ˈ n aɪ s is a common and widely distributed type of metamorphic rock gneiss is formed by high temperature and high pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks orthogneiss is gneiss derived from igneous rock such as granite. The table below shows examples of common metamorphic rocks.

This will result in the formation of an igneous rock not a metamorphic rock. Its composition is equal to that of granite but forms alternating layers of clear and dark minerals. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. There are hundreds of metamorphic rocks across the face of the earth with different compositions and.

Paragneiss is gneiss derived from sedimentary rock such as sandstone. Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure. Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window. The extensively known example of non foliated metamorphic rock is a marble.

Its basic component is calcium carbonate. Non foliated metamorphic rocks do not have a banded or layered appearance. In order to create metamorphic rock it is vital that the existing rock remain solid and not melt. If there is too much heat or pressure the rock will melt and become magma.

Granite is a light colored igneous rock. Composed of quartz feldspar and mica. 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. Some examples of metamorphic rocks are gneiss slate marble schist and quartzite.

Other examples include quartzite hornfels and novaculite.
