Thermodynamic estimation the compressibility of ferropericlase under high pressure
Source abstract
Abstract
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.
