Abstract
In his recent classification of anorthosites,Berrange(1966) has interpreted the West Greenland anorthosites as orognic-plutonic types. However, recent work has shown that in the central high-grade region of Fiskenaesset nearly all the anorthosite horizons have intense chromite layering. The anorthosites have been metamorphosed under granulite facies conditions and subsequently downgraded. The conclusions are made that the West Greenland anorthosites as a whole should be classified as pre-orogenic stratiform types and that most of the present features are of secondary origin and should not be confused with those of the orogenic-plutonic association.
