Anorthosites and their associated rock types have been a subject of controversy for a considerable number of years. Several genetic theories have been suggested to explain the observed field characteristics, but none have been completely accepted by authorities on the subject. Theories on the origin of anorthosite may be classed as magnetic, metasomatic, and anatectic, and all contain useful ideas. Where an aspect of the problem appears to be successfully solved by one genetic theory, another remains embarrassingly unexplained. It is quite possible that a complex series of events is responsible for the formation of the anorthosites and their associated rock types. Kranck (1961) points out that, "The origin of the anorthosites is almost as controversial a subject as the granite problem.”
