oxide minerals of the Tellnes ilmenite norite are more primi tive than those sampled by us in the layered intrusion Thus the Tellnes deposit cannot be correlated with late stages in evolution of the Bjerkreim Sokndal intrusion nor with the internal mangerite dike system in the Åna Sira Anorthosite as suggested by Krause et al 1985
