Model study suggests a diamond layer at Mercury’s core-mantle boundary
Proposed scenario for diamond formation at the core-mantle boundary of Mercury. (a) Crystallization of the carbon-saturated silicate magma ocean and the potential, but unlikely, early production of diamond at its base. Graphite was the major phase formed in the magma ocean and accumulated at the surface to form an ancient graphitic crust. (b) During crystallization … Read more
