Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window. When a granite pluton formed deep underground is uplifted and exposed at the surface. Granite ˈɡrænɪt is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granite belongs to the intrusive category of igneous rock which means it formed below the earth s surface as magma slowly cooled and crystallized.

The most common group of minerals in earth s crust are the. This granite has very large mineral grains indicating the rock cooled very slowly. The most common hard rocks are granite marble and slate. Granite is an igneous rock that was never exposed to air or water as it cooled down allowing it to solidify in a very dense form.

Marble is metamorphosed limestone quartzite is metamorphosed sandstone and gneiss another common metamorphic rock sometimes begins as granite. Marble and slate are both metamorphic rocks which have been formed over time by the compression of limestone and shale respectively. Orthogneiss is gneiss derived from igneous rock such as granite. Schist with garnet crystals red round minerals top of rock.

These rocks form via high temperature and high pressure metamorphic processes acting on sedimentary or igneous rocks. All metamorphic rocks began as other rocks parent rocks that were then subjected to elevated. Paragneiss is gneiss derived from sedimentary rock such as sandstone. Granite and gabbro have a similar texture.

Differing amounts of muscovite biotite and hornblende type amphiboles. The table below shows examples of common metamorphic rocks. Gneiss is formed by high temperature and high pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. It is in fact the most common and widely distributed type of metamorphic rock.

Granite containing potassium feldspar plagioclase feldspar quartz and biotite and or amphibole. Remember these rocks are formed under extreme heat and pressure.
