Includes bibliographical references. / The Sverdrupfjella Group in western Dronning Maud Land forms part of a 1200 Ma to 900 Ma orogenic belt which experienced a thermal overprint at around 500 Ma. Although the degree of tectonic reworking during this later event remains uncertain, evidence for late fluid alteration is widespread. In this study, the high-grade metamorphic rocks which make up the Sverdrupfjella Group were sampled in the central Kirwanveggen area. The stable isotope and whole-rock composition of these rocks have been determined, in order to test whether zones of intense fluid-rock interaction can be used as evidence for Pan African overprinting of Grenvillian orogenesis in western Dronning Maud Land.
