Igneous Granite With Feldspar Environment

The type of igneous rock determined by its mineral composition can be gauged from its relative darkness.

Igneous granite with feldspar environment.

Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Strictly speaking granite is an. 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. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock.

It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Alkali feldspar any of several common silicate minerals that often occur as variously coloured glassy crystals. It forms from the slow crystallization of magma below earth s surface. Each has a different composition according to where its magma collected.

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. Being mostly quartz and feldspar the granites are light in colour. Transparent highly coloured or iridescent varieties are sometimes used as gemstones.

Of the hundreds of named igneous rocks consider the three rocks granite andesite and basalt. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Formally granite is a plutonic rock that is composed of between 10 to 50 quartz typically semi transparent white and 65 to 90 total feldspar typically a pinkish or white hue.
