The copper deposits of the Birtavarre district, Troms, Northern Norway. Kopperforekomster i Birtavarre-området Troms.
The report gives the results of a 4-year (1952-55) programme for the investigation of a former copper-mining area in the north of Norway, carried out by the Geological Survey of Norway (NGU). The stratigraphy and structure of the district have been discribed in a previous NGU publication (Padget 195...

The report gives the results of a 4-year (1952-55) programme for the investigation of a former copper-mining area in the north of Norway, carried out by the Geological Survey of Norway (NGU). The stratigraphy and structure of the district have been discribed in a previous NGU publication (Padget 1955). The ore deposits occur in one particular division (Ankerlia Series) of the layered Caledonian schists which underlie the whole area (see Plates 1 and 2). No deposits have been found outside this division. The greatest concentration of deposits occurs in the centre area along the south limb of a major, open E-W anticline (Moskogaissa anticline). In the same area the normally NW-plunging linear structures of the schists show a marked swing to an E-W direction (Plate 2).
