The Earth's outer core does not dissolve into the mantle due to chemical immiscibility and thermodynamic equilibrium

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the Earth's outer core does not dissolve into the mantle due to chemical immiscibility and thermodynamic equilibrium?

No. Recent studies on core-mantle interactions show that chemical reactions, iron-water exchange, and material transfer do occur across the boundary, refuting the claim that the core remains separate solely due to absolute immiscibility and equilibrium.
