A phaneritic, intrusive igneous rock characterized by a predominance of plagioclase feldspar
The second, or Labrador series is characterized, as already remarked, by the predominance of great beds of anorthosite, composed chiefly of triclinic feldspars . . .
A granular igneous rock composed almost exclusively of a soda-lime feldspar, usually labradorite
Type of igneous rock composed predominantly of calcium-rich feldspar. It is considerably less abundant than either basalt or granite, but the complexes in which it occurs are often immense. All anorthosites found on the earth consist of coarse crystals, but some from the moon are finely crystalline
