A late Carboniferous palaeomagnetic pole recorded from a syenite still, Stabben, Central Norway

Abstract

High-blocking remanence components ( D = 192°, I = − 12°) recorded in a syenite sill from the Island of Stabben, Central Norway, are considered to be of primary/deuteric origin and to correspond to the radiometric age (297 Ma). The upper part of the sill and the contact gneiss, however, are strongly contaminated by a younger magnetic overprint ( D = 8°, I = 59°). The primary component may represent a reliable Upper Carboniferous pole determination from Western Scandinavia, whereas the secondary component most probably relates to Cretaceous or younger faulting.
