On Earth, anorthosite is not as common as basalt or granite and is composed of coarse crystals. Large masses of anorthosite, however, do occur and can be found in such locations as the New England region of the United States, Zimbabwe, and Canada. A particularly large and well-known series of anorthosite complexes occurs in the Adirondack Mountains and is referred to as the Adirondack Fe-Ti deposits. This term is reflective of the iron and titanium ores that may be readily mined from the rock complexes in the form of ilmenite, magnetite, rutile, and hematite. Anorthosite is also sometimes quarried for use as crushed rock or as a building material.
