    Abstract

    The Tertiary Werner Bjerge complex is divided into a basic complex, a northern complex and a nepheline syenite complex. The basic complex consists of cumulate rocks (ranging from ultramafic to gabbros). The northern complex includes a wide range of felsic rock types, of which two granites have been examined. In the nepheline syenite complex the rock types investigated include foyaites, a tinguaite, and quartz-bearing pegmatite. It is concluded that the geochemical coherence between various rock units of the intrusion suggests a comagmatic origin, while the close similarities between the mineralogies of the Kangerdlugssuaq and Werner Bjerge alkaline complexes suggest a similar origin.-C.N.
