A palaeomagnetic study has been performed on Palaeo-Mesoproterozoic basic intrusions from three crustal blocks of the Ukrainian Shield. At least three different generations of dykes has been identified and positive field tests can be demonstrated for some of them. A sequence of 2.1 to 1.72 Ga apparent polar wander has been defined on basis of the new palaeomagnetic and Ar/Ar data presented here and on basis of old data from anorthosites. The calculated poles are significantly different from poles of similar age from the Fennoscandian Shield. Although the poles are not perfectly coeval the tectonic reconstructions demonstrate that the Ukrainian Shield collided with Fennoscandia at 1.80-1.85 Ga and then rotated some 45° into its present relative position.
