Color variation is a response to the percent of each mineral found in the sample.
Granite s mineral composition is mainly quartz and feldspar.
The crystals in granite provide a variety of mixed colors feldspar pink or red mica dark brown or black quartz clear pink white or black and amphibole black.
Granite is an igneous rock of plutonic origin meaning it formed beneath the surface rather than above ground.
It is mainly composed of quartz and feldspar although it may contain smaller amounts of other minerals such as mica and amphibole.
It forms from the slow crystallization of magma below earth s surface.
It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.
