Make-up
The microcontinent consists of the prominent bathymetric high, the Jan Mayen Ridge and several subsidiary ridges and intervening basins towards the south and west. Investigations using seismic reflection and refraction data have identified two passive margin sequences on the two sides of the microcontinent. Faults mapped on seismic reflection data are roughly N-S trending in the northern part becoming SW-NE trending to the south. The crustal thickness reaches a maximum of 16 km on the eastern side of the main ridge.
