- Jan Mayen is made up of basalt flows and pyroclastic flow related mafic deposits. The two most recent eruptions were in 1970 and 1985, although the Central Crater and Egg Island craters on the southern side of the mountain have continuous fumarole activity.

The geology of Jan Mayen is part of the larger Jan Mayen Ridge, an undersea volcanic ridge that forms the boundary of the Iceland Plateau to the northeast. North of the island, the sea floor slopes steeply, plunging a depth of greater than two kilometers in the vicinity of Jan Mayen Rift Zone.
Jan Mayen is an Arctic island situated in the middle of the North Atlantic Ocean, at the northernmost tip of the submarine aseismic Jan Mayen Ridge just southward of the seismically active Jan Mayen Fracture Zone.

The Jan Mayen microcontinent (JMMC) is a structural entity encompassing the Jan Mayen Ridge and the surrounding area, including the Jan Mayen Basin, the Jan Mayen Basin South, the Jan Mayen Trough and the Southern Ridge Complex (SRC) (Fig. 1; Table 1).
Mar 16, 2022 · The Jan Mayen microcontinent within the central NE-Atlantic formed during two breakup processes that involved seven distinct magmatic and tectonic phases over a period of ∼40 million years (∼63–21 Ma). Compilation of geophysical, geological, and geochemical data has illuminated details of rifting processes during the two breakup events.

The complex pattern of volcanic zones in Iceland is offset WNW by the Tjornes Fracture Zone (S mundsson, 1974) to the Kolbeinsey Ridge (Iceland-Jan Mayen Ridge by Tal wani & Eldholm, op.cit.), which is the active spreading ridge north of Iceland.

May 12, 2016 · The wedging of the Jan Mayen plate (microcontinent) into the triple junction of the plates (Greenland, Eurasian, Jan Mayen) promoted intense volcanism and the formation of two large volcanic complexes: (1) the Greenland‒Faroes and the (2) Trail‒Vøring.
A new tectonic scheme is proposed for the evolution of the southern Norwegian-Greenland Sea. The Jan Mayen fragment began to split from the East Greenland margin at the end of anomaly 20 times (43 Ma).
