Breakup and seafloor spreading between Greenland and Eurasia established a series of new plate boundaries in the North Atlantic region since the Paleocene. A regional kinematic model from the pre-breakup to present day is assuming that Eurasia and Greenland moved apart as a two plates system. However, regional geophysical datasets show that this system suffered several adjustments since its inception and additional temporal plate boundaries existed in the NE Atlantic.
The formation of a highly extended or even fragmented Jan Mayen microcontinent was one of the consequences of plate boundaries relocations. The major Oligocene plate boundary reorganization (and microcontinent formation) might have been precluded by various ridge propagations NE and possible SW of Jan Mayen microcontinent. The existence of additional (short lived) plate boundaries within the North Atlantic oceanic area has been tested using statistical methods.
