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. Itsnorthern part (Nord-Jan) is formed by the large Beerenberg ...
Jan Mayen is a volcanic island located in the Norwegian-Greenland Sea (Fig. 1). It is situated on the Jan Mayen microcontinent, which separated from East Greenland and became completely isolated around ~21.56 Ma (Blischke et al. 2016 and references therein). The northern end of the island is located close to the Jan Mayen Fracture Zone (JMFZ ...
May 12, 2016 · Two main events determined the formation, geological history, magmatism, and geodynamics of the Jan Mayen microcontinent: (1) drift of this segment of the Laurasian plate over the Iceland plume in the Early Paleogene; (2) propagation of the rift zone of the mid-Atlantic Ridge into this region and separation of the Jan Mayen lithospheric block from northeastern Greenland. The lithosphere was ...
Modern active island arcs and their surroundings consist of two main physiographic zones-a volcanic ridge or arc and a submarine trench. Rocks in island arcs fall into three groups, the origin of which can be interpreted in terms of plate tectonics and of geological processes in the two zones and surrounding ocean floor. The groups are (1) volcanic arc deposits, consisting of undeformed ...
Dec 7, 2020 · A vertical cross-section of whole-mantle tomography passing through central Greenland and Jan Mayen (right). We can see that the Greenland plume is the heat source for the Jan Mayen volcano ...
Feb 3, 2015 · The island of Jan Mayen in the North Atlantic Ocean is home to the world’s northernmost active subaerial volcano, Beerenberg. Of the five known historical eruptions on the island, the locations of two eruptions (1732 and 1818) have not been accurately located. It is known that the 1732 and 1818 eruptions occurred on the south flank of Beerenberg, and several eruption sites have been proposed ...
Remote Jan Mayen Island, located in the Norwegian Sea along the Mid-Atlantic Ridge about 650 km NE of Iceland, consists of two volcanic complexes separated by a narrow isthmus. The large Beerenberg basaltic stratovolcano (Nord-Jan) forms the NE end of the 40-km-long island, which is ringed by high cliffs.
