Gneiss however is distinguished from granite by its strong fabric and alternating dark and light colored bands.

Composition of granite geology.

Different granites have unique chemical compositions that produce different mineral proportions. This rock gained popularity for gravestones around the end of the 19th century and is the most common stone in contemporary cemeteries today. Granite is a good approximation for the continental crust both in density and composition. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture.

Felsic rocks are less dense than mafic and ultramafic rocks and thus they tend to escape subduction whereas basaltic or gabbroic rocks tend to sink into the mantle beneath the granitic rocks of the continental cratons. 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 coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. This chart illustrates the generalized mineral composition of igneous rocks.

The presence of quartz is a good indicator of granite. The only commonly igneous rock in the historic gravestone materials roster granite is made up of quartz feldspar and other interlocking materials such a biotite. Granite has a felsic composition and is more common in recent geologic time in contrast to earth s ultramafic ancient igneous history. No radiometric ages available for granite facies but it is conceivable that the two facies are different in age.

A rock with a similar composition and appearance as granite gneiss can form through long and intense metamorphism of sedimentary paragneiss or igneous rocks orthogneiss. Granites and rhyolites compositionally equivalent to granite but of a fine grain size are composed mainly of orthoclase feldspar quartz plagioclase feldspar mica and amphibole. A rock expert will define the exact composition of the rock and most experts will not use granite to identify the rock unless it meets a certain percentage of minerals. Granite facies intrudes both the kittery formation and the tonalite and granodiorite facies and covers an area of about 45 sq km.

It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. In fact granitic rocks are generally classified by their mineral proportions and given names such as granite granodiorite tonalite and diorite. A simple course on rocks along with granite mica and amphibole minerals can be described as a coarse light magmatic rock consisting mainly of feldspar and quartz. Strictly speaking granite is an.
