What Is Granite And How Is It Formed?

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). Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock.
