Abstract
Original and published material was used to examine the history of eruptive magmatism at the Jan Mayen hotspot, although the scientific community is not unanimous in recognizing it as part of the Iceland plume. It is shown that occurrences of alkaline magmatism that is characteristic of present-day volcanoes on Jan Mayen Island started in the Early Eocene and were caused by the passage of eastern Greenland near the plume. Magma was supplied to the Jan Mayen hotspot via deep-seated faults and channelways from relict and new magma chambers during the Oligocene, as well as the Miocene, Pliocene, and Quaternary periods. These chambers were probably replenished by cycles of magmatism at the Iceland plume and as a result of local magma generation in the Jan Mayen transform fault zone; the Jan Mayen volcanoes are currently observed to migrate towards this fault.
