We report geochemical and Hf-Pb-Sr-Nd isotopic analyses of a suite of picrites and associated high-MgO volcanic rocks (6–17 wt.% MgO) from the Kerguelen Archipelago, which are rare compared to other oceanic islands, to better constrain the nature and the origin of components present in the Kerguelen...
