- The island marks the northernmost part of the Jan Mayen Microcontinent, a submerged fragment of continental crust that was rifted away from eastern Greenland about 20 million years ago. The island consists of young basaltic rocks erupted from the Jan Mayen Fracture Zone, which bounds the microcontinent on the north.

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.
Abstract. 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. Volcanic rocks of Quaternary age predominate on the island.

May 12, 2016 · Recent volcanoes of the Jan Mayen hot spot are fed by magma from the Iceland plume as well as from relict and newly formed cambers in a zone of deep-seated Jan Mayen transform faults. Two main events determined the formation, geological history, magmatism, and geodynamics of the Jan Mayen microcontinent: (1) drift of this segment of the

Oct 15, 2014 · Geology. Last active in 1970 and 1985, the land is raw and barely vegetated in most places. It appears as a rocky moonscape of alternating layers of basaltic lava flows and ash or tephra—save for a few sparse areas with dandelions, arctic flowers, and thick beds of mosses.
Jan Mayen was formed by the Jan Mayen hotspot and is defined by geologists as a microcontinent. [2] Although administered separately, in the ISO 3166-1 standard, Jan Mayen and Svalbard are collectively designated as Svalbard and Jan Mayen, with the two-letter country code "SJ".
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.
