Palaeomagnetism of the Carboniferous E–W dyke swarm in Argyllshire

Abstract
Synopsis: The majority of 21 sampled dykes in this swarm have a coherent reversed magnetisation linked to the c. 320 Ma, Lower-Upper Carboniferous boundary, age of intrusion. Fifteen sites define a palaeopole at 354.6°E, 35.0°S (dp = 2.5, dm = 5.0), coinciding precisely with the apparent polar wander path for Europe at 320 Ma.
