The other rocky planets mercury venus and mars are covered with basalt as is the ocean floor of earth. Granite is a coarse grained light colored igneous rock composed mainly of feldspars and quartz with minor amounts of mica and amphibole minerals. Granite is an igneous rock made up of primarily quartz feldspar micas amphiboles and a mixture of additional trace minerals. Rocks containing less than 20 percent quartz are almost never named granite and rocks containing more than 20 percent by volume of dark or ferromagnesian minerals are also seldom called granite.

Biotite may occur in granite of any type and is usually present though sometimes in very small amounts. Granite is the signature rock of the continents. Granite ˈɡrænɪt is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Intrusive rocks form from molten material magma that flows and solidifies underground where magma cools slowly.

The minor essential minerals of granite may include muscovite biotite amphibole or pyroxene. Granites can be predominantly white pink or gray in color depending on their mineralogy. Eventually the overlying rocks are removed exposing the granite. More than that granite is the signature rock of the planet earth itself.
