Paleomagnetic studies of rapakivi complexes in the Fennoscandian Shield : Implications for the origin of Proterozoic massif-type anorthosite magmatism [PDF]
, 2021 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 similar to 1640-1497 Ma poles are clustering on low latitudinal positions. By combining
