Core Density Deficit

Core Density Deficit is a geophysical construct that quantifies the discrepancy between the observed density of Earth's metallic core and the density predicted by high-pressure mineral physics models of pure iron–nickel alloys, indicating the presence of light elements such as oxygen, silicon, or sulfur in the core composition.
