Abstract
The area east of Ataa Sund consists mainly of amphibolite facies grade Archaean gneisses, amphibolites and granites. Intense early Proterozoic deformation led to low-angle ductile imbrication of thrust sheets with movement directions to the west. Late tectonic Proterozoic basic sills with olivine-rich cumulates were intruded along the thrust sheets.
