Inner core composition paradox revealed by sound velocities of Fe and Fe-Si alloy
The origin of the observed low shear wave velocity in the solid inner core is unclear. Here, the authors report shear wave velocities of iron and iron-silicon alloy under Earth’s core conditions by shock compression and find that neither the effect of temperature nor incorporation of Si can explain...
