- Density and magnetic properties were determined on some 1350 rock samples, taken from the different lithologies in the Caledonides of Jmtland, Sweden. The density determinations showed a strong trend of increasing density when moving from east to west in the investigated area. There was also a general increase in density upwards in the tectono-stratigraphy from the autochthon to the Seve of the Seve-Kli Nappe Complex. The determination of magnetic properties showed that east of the Caledonian Front the dominating high-susceptibility rock was the Rtan granite. In the Eastern Complex, west of the Caledonian Front, high-susceptibility rocks were found in the parautochthonous and allochthonous crystalline basement, whereas in the Western Complex the Ottfjllet dolerite in the Srv Nappe was the dominating high-susceptibility rock.

- The building of a very quiet non-magnetic house can raise special problems in Precambrian areas and in the cold climate of northern Sweden. The special precautions taken in the construction of a non-magnetic house belonging to the University of Lule have resulted in a laboratory for high-precision rock magnetic and palaeomagnetic work. The mean total field in the house one metre above the floor is 52011 ±3 nT and the maximum variation inside is 12 nT. The geographical, position is the mountain Rånekölen, latitude 65.8°N, longitude 22.3°EGr, about 30 km north of Luleå.
