Paleomagnetic studies have been performed on five rapakivi related complexes in Sweden and Finland. Poles of varying quality have been defined and the majority of the ∼1640–1497 Ma poles are clustering on low latitudinal positions. By combining data from ∼1500 Ma intrusions a new high-quality pole (Plat: 13°N; Plon: 190°E; A₉₅: 11°, K: 14) for Baltica has been defined. Tectonic reconstructions, on the basis of the new data and previously published high-quality data, indicate that Baltica experienced stable low latitude to equatorial positions during 1640–1470 Ma, temporally coinciding with globally pronounced rapakivi-anorthosite magmatism. Our study argues against single hotspot source for  ∼1640–1620 Ma, ∼1590–1520 Ma, and 1470–1410 Ma rapakivi-anorthosites, but supports a model of large-scale superswell under a stationary low-latitude position of supercontinent Nuna for the origin of rapakivi-anorthosite magmatism. However, a possibility for convergent tectonism as the origin cannot be ruled out.
