Summary
In this account we describe a modern Petrophysical and Palaeomagnetic Laboratory in terms of construction details, software and applications. The Norwegian Geological Survey Laboratory allows definite measurements of magnetic susceptibility, weight, volume, density and the natural remanent magnetization (NRM). These parameters are of crucial importance in the regional interpretation of aeromagnetic and gravity data. The stability of NRM is tested by means of thermal and alternating field demagnetization, thus allowing carefully planned palaeomagnetic studies. Such studies provide a method in dating of rocks or orogenic/hydrothermal vents, azimuthal orientation of borecores and assists tectonic modelling on a variety of crustal scales.
