Mineral-melt partition coefficients and the problem of multiple substitution mechanisms: insights from the rare earths in forsterite and protoenstatite
A trace element may substitute into a mineral by more than one substitution mechanism, complicating the thermodynamic description of its partition coefcients. In order to understand this phenomenon better, the mineral/melt partition coefcients for all 14 rare earth elements (REE) plus Y and Sc were measured experimentally for coexisting forsterite and protoenstatite in the system CaO-MgO-SiO2-Al2O3-TiO2 at 1406 °C and atmospheric pressure. For both phases, the results show these large trivalent...[Show more]
