Recent field studies have shown that the rocks in NE Sulitjelma described by Th. Vogt in 1927 as parts of one large basic intrusion consist of a layered basic igneous complex which has been thrust over a series of metavolcanic rocks. This is in a.ccord with the conclusions reached by Kautsky in 1953. However, the thrusting appears to be syn-metamorphic, rather than postmetamorphic, and not all the nappes described by Kautsky in Sweden can be recognized on the Norwegian side of the border.
