From: Sound velocity of CaSiO3 perovskite suggests the presence of basaltic crust in the Earth’s lower mantle

Extended Data Fig. 3

The elemental energy-dispersive spectroscopy mappings of Ca, Si, Al, Mg, Na, Cl and Au, superimposed on the backscattered-electron image of the cross-section, showed no chemical zoning in the CaSiO3 sample or at the interface with the sample and the other cell components.
