Seismic imaging of the Scandinavian Caledonides to define ICDP drilling sites

Highlights
► COSC aims to further our understanding of the Caledonides and collisional orogens. ► A reflection seismic site survey reveals a highly reflective subsurface. ► The Seve nappe is easily distinguishable, correlating well with surface geology. ► The basal décollement is found at 1.5 km in the east and at 4.5 km in the west. ► On the basis of the new data, two locations are proposed for the two core-holes.
