A marked change in crustal thickness is seen at the deformation boundary between the undisturbed Archaean core in the south and reworked Archaean gneiss in the foreland of the Nagssugtoqidian orogen in West Greenland. In addition, intra-crustal boundaries can be tentatively interpreted. This is the first information on crustal structure in the area, which is known for kimberlite, carbonatite and ultramafic lamprophyre occurrences, and diamond exploration.
