Abstract/Summary

In Dronning Maud Land (DML), East Antarctica, a ca. 620-500 Ma mobile belt dissects the continent. This ca. 1000 km wide orogen has been linked to the East African Orogen on the one hand and relationships to the Kuunga orogen were suggested on the other. The mobile belt reworks mainly Grenville-age crust. The foreland hinterland boundaries are clearly defined in the Heimefrontjella (western DML) and in eastern DML (Sor Rondane), both as major dextral transpression zones. The mobile belt is characterized by medium to high-grade metamorphism between ca. 620 - 500 Ma.
