Paleomagnetic and geochronological studies on Paleoproterozoic diabase dykes of Karelia, East Finland-Key for testing the Superia supercraton

Paleomagnetic results are presented for two Paleoproterozoic mafic dykes in the Taivalkoski area in northern Karelia Province of the Fennoscandian shield where, based on K-Ar data, the crust has seen minimal effects of the otherwise pervasive 1.8–1.9Ga Svecofennian orogeny. Within this study a new U–Pb baddeleyite age of 2339±18Ma has been determined for one of the E–W trending dykes (dyke AD13).
