Mercury isotopes were measured in a suite of well-characterized (for Sr-Nd-Pb-Hf isotopes) ocean island basalts from Tubuai, Pitcairn, Samoa, and Iceland. Lavas from the Afar hotspot were also examined. The data show that ocean island basalts exhibit both mass-dependent fractionation of Hg isotopes....
