Usually granite is pink or greyish coloured, medium to coarse-grained, evenly granular rock. It is the lightest coloured variety of intrusive rock. The grains are usually white/pink orthoclase feldspars, with lesser amounts of white/grey plagioclase feldspar, and quartz. Small amounts of dark biotite and / or hornblende are usually present and best identified with the use of a hand-lens.
Large volumes of granitic rocks are associated with active continental margins where they form enormous batholiths.
