Palaeomagnetism of the Lower Carboniferous Billefjorden Group, Spitsbergen
Abstract Palaeomagnetic data from mid to late Palaeozoic rocks are potentially valuable for testing models of the assembly of Spitsbergen and for determining the palaeo-position of parts of Spitsbergen relative to the major tectonic elements that comprised the Old Red Continent. Fine-grained red san...
