Geochemical Evidence for Excess Iron in the Mantle Beneath Hawaii

Humayun, Munir; Qin, Liping; Norman, Marc


Chemical interaction of Earth's mantle with the liquid outer core should influence the mantle's iron content. Osmium isotope ratios in Hawaiian lavas indicate a mass flux of ≤1% core to the mantle, which is the immediate source of these lavas. We presen
