Short summary
We performed experimental measurements of elastic parameters of fayalite. The idea is to better define the effect of olivine Fe content on these parameters and test how sensitive these are when adjusting mineralogical models to seismic data. The trend of the olivine shear modulus with Fe content is well defined, but that of the bulk modulus remains less constrained, and more experiments on olivines with different Fe compositions are needed.
