Late Cenozoic (<35-25 Ma) intraplate volcanism adjacent to and within Svalbard from refs. 6,8,10,33; Interpreted seamounts in NE Atlantic from ref. 11; High Arctic Large Igneous Province (HALIP) from ref. 17; North Atlantic Large Igneous Province (NALIP) from ref. 43; Depth to lithosphere-asthenosphere boundary (LAB) and Moho temperature contours from ref. 54; Extent of Arctic Azolla from ref. 27. ACEX and ODP drilling sites, and location of used seismic reflection profiles (1-4) are indicated (see also S1). EVZ/WVZ: Eastern/Western volcanic zone, SMZ: Sparsely-magmatic zone. Box in bottom-right indicates a simplified Sr-Nd isotopic trend of Late Cenozoic basalts within the studied region (see also S6). AB Amundsen Basin, Bjø Bjørnøya, GR Gakkel Ridge, JMMC Jan Mayen micro-continent, LT Lena Trough, MJR Morris Jesup Rise, MS Mosby Seamount, NB Nansen Basin, SB Sophia Basin, S-N/Q Neogene/Quaternary basalts in Svalbard, YP Yermak Plateau. Inset map: Arctic Bathymetry (IBCAO) with areas affected by Late Cenozoic intraplate volcanism. Red box indicates area displayed. Other abbreviations/explanation in text and “Methods” section.
