Remanent magnetization of two intrusive bodies in southeastern Finland
Direction of natural remanent magnetization (NRM) was measured for a diabase from the intrusive contact of rapakivi granite (1650 Ma) and for a granodiorite intrusion (1810 Ma). The results, although statistically poor, suggest that the apparent polar wandering curve drawn earlier for the Middle Pre...

| Summary: | Direction of natural remanent magnetization (NRM) was measured for a diabase from the intrusive contact of rapakivi granite (1650 Ma) and for a granodiorite intrusion (1810 Ma). The results, although statistically poor, suggest that the apparent polar wandering curve drawn earlier for the Middle Precambrian of Fennoscandia from about 2000 to 1200 Ma is correct and not caused by differences in uplift rates. |
