Abstract

It has been suggested that the ultrabasic and basic gneiss masses in the Lewisian near Scourie and Drumbeg are layered igneous bodies possibly containing primary igneous mineral assemblages. This hypothesis is reviewed in all its aspects and rejected on the grounds of field relationships, mineralogy, and geochemistry.
