- Abstract
Here we present reconstructions indicating the stationary position and paleogeography of the Iceland plume, as well as its direct connection to the Mesozoic–Cenozoic large igneous provinces of the northern Atlantic and the Arctic. The main evidence for the stationary position of the Iceland hotspot comes from paleomagnetic data for the trap formation of the Franz Josef Land archipelago. Our reconstructions show that the Barents Sea magmatic province included in these traps belongs to the trace of the Iceland plume and formed as part of the High Arctic Large Igneous Province during a single relatively brief event ca. 125 Ma. Older pulses of basaltic magmatism inferred previously for the Franz Josef Land archipelago for the Early and Middle Jurassic period do not have known analogs in adjacent territories of the present-day Arctic.
