To better constrain Baltica's position within Pangea, we conducted a palaeomagnetic study of Permo-Triassic dykes from the Oslo Graben, as a follow-up to an initial, but rather limited, study by Torsvik and colleagues in 1998. The age of these so-called Lunner dykes had previously been determined as ~240 Ma in that study, but details in their analyses and new 40Ar/39Ar ages reveal that there may have been some argon loss in the initially dated dyke minerals and that a combined (weighted mean)...[Show more]
