IGNEOUS

Granite Basics:

Three things distinguish granite.

First, granite is made of large mineral grains that fit tightly together, which is where its name came from.

Second, granite always consists of the minerals quartz and feldspar, with or without a wide variety of other minerals (accessory minerals). The quartz and feldspar generally give granite a light color, ranging from pinkish to white. But that light background color is punctuated by the darker accessory minerals. Thus classic granite has a "salt-and-pepper" look. The most common accessory minerals are the black mica biotite and the black amphibole hornblende.

Third, almost all granite is igneous (it solidified from a fluid state) and plutonic (it did so in a large, deeply buried body or pluton). The random arrangement of grains in granite—its lack of fabric is evidence of its plutonic origin. (about.com)
