| Abstract | Recent experimental work and calculations have shown that the primitive mantle abundances of six moderately siderophile elements (Fe, Ni, Co, Mo, W and P) and one highly siderophile element (Re) are consistent with metal-silicate equilibrium at the base of a 700-900 km deep magma ocean in the early Earth (i.e. [1]). Whereas heterogeneous accretion models can successfully explain the chondritic relative abundances of the highly siderophile elements (PGE's, Au), they cannot explain the depletion patterns of the volatile moderately siderophile elements such as Ga, Sn and Cu (e.g. [2]). This equilibrium magma ocean model must be tested for these highly and moderately siderophile elements. We have initiated systematic studies of three volatile, moderately siderophile elements whose mantle abundances are well characterized, and assess the effect of P, T, fo~ and metal and silicate liquid composition on the magnitude of four highly siderophile elements, Au, Re, Pd and Pt. |
