Density and magnetic properties of rocks in the Caledonides of Jämtland, Sweden

• 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.
