摘要
The elastic properties of (Mg1-xFex)O ferropericlase are essential to analyze seismic data and to constrain its chemical composition in the lower mantle. In this study, we suggest a simple thermodynamic model that enables the estimation of the bulk moduli of (Mg1-xFex) O ferropericlase as a function of component x in terms of the elastic data of the end members. Our calculated bulk moduli compare favorably with reported experimental data when uncertainties are considered. (C) 2016 Author(s).
