Most commonly grey (gray if American), but it can be various other colours such as black and blue, although these are much rarer forms. Colors in granite include pink, red, orange, white, gray, green, black, or light to moderate yellow.
Kingston Granites was created in 1898.
The pink color in some granites is due to the coloration of orthoclase (alkali) feldspar.
Granites are mainly used for construction of firm and decorative platforms.
Granites and basalts.
No Granites are usually intrusive rocks.
Basalts are higher in plagioclase feldspar, pyroxene, olivine and iron content than granites, which are typically higher in quartz, alkali feldspars, and micas.
Granite is an intrusive igneous rock and comes from magma. It is a very hard, granular, crystalline rock that is mainly composed of quartz, mica, and feldspar.
The intrusive granites which contain ores are the product of solidified magmas, most probably ones that have undergone significant magmatic differentiation.
Among the minerals that contribute to granite's color are quartz (white/gray), feldspar (pink/gray), biotite (black), and iron oxides (red/brown). The combination of these colors makes each granite slab unique and visually appealing.
