Description
<jats:title>Abstract</jats:title><jats:p>Seismological observations show that, in some regions of the lower mantle, an increase in bulk sound velocity, interestingly, occurs in the same volume where there is a decrease in shear velocity. We show that this anti-correlated behavior occurs on cation substitution in bridgmanite by making single crystal elasticity measurements of MgSiO<jats:sub>3</jats:sub> and (Mg,Fe,Al)(Si,Al)O<jats:sub>3</jats:sub> using inelastic x-ray scattering in the ambient conditions. Cation substitution of ferrous iron and aluminum may explain large low shear velocity provinces in the lower mantle.</jats:p>
