Highlights • 238U-230Th-226Ra disequilibria in lavas from Northern Kolbeinsey Ridge (Eggvin Bank) support an eclogite-rich mantle source. • Jan Mayen Island lavas are likely the product of upwelling in a mantle plume containing moderate quantities of eclogite. • Low (226Ra/230Th) ratios in global OI...
