" Aside from its hardness, granite is characterized by a mineral profile heavy in quartz - often ranging between 20 and 60 percent - and feldspars. The rock is often phaneritic, which means it consists of an even grain, but much variety exists: Some granites show some large crystals embedded in fine-grained structure, which can be due to a marked shift in the rate of magma cooling in its formation. Depending on mineral type and proportion, granite usually ranges from pale to dark gray in hue. Quartz monzonite is typically medium- to coarse-grained, and often of a darker cast than granite. A monzonite rock is one with a quartz content of 10 percent of less; above that value, it is classified as quartz monzonite. "
