An 800 km long basin system developed along the East Greenland margin since the Late Palaeozoic in which the Jameson Land Basin forms the southern part of the system. Along the margins of the Jameson Land Basin there are occurrences of barite, copper, lead, zinc and silver, which are particularly abundant in the northern part of the basin’s eastern margin in the Wegener Halvø area (Fig. 1). Structures and stratigraphic architecture play important roles in the mineralisation distribution, so detailed mapping is essential. We used 3D photogeology combined with geophysical data to map the different stratigraphic units, faults and dykes in three dimensions.
