Igneous Granite With Feldspar Environment

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.

Igneous granite with feldspar environment.

It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. The alkali feldspars are primarily. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar.

Transparent highly coloured or iridescent varieties are sometimes used as gemstones. The type of igneous rock determined by its mineral composition can be gauged from its relative darkness. Each has a different composition according to where its magma collected. Being mostly quartz and feldspar the granites are light in colour.

They are used in the manufacture of glass and ceramics. It forms from the slow crystallization of magma below earth s surface. 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.
