Upper mantle shear-wave velocity conversions to temperature and density: open-source V2RhoT_gibbs sheds light into challenges and possibilities Open
Variations of seismic wave speed, in particular shear-wave velocity (vs), are largely temperature controlled in the Earth’s mantle. Seismic tomography models thus provide us with insights into upper mantle temperature variations, the…
