Researchers find rust and diamonds at the Earth’s core-mantle boundary. Scientists found carbon separated from the liquid iron-metal alloy and forms diamonds. The scientists discovered that water and metal react to form iron oxides and iron hydroxides, just like rusting on Earth’s surface. The discovery could shed light on the understanding of the carbon cycle in the Earth’s deep interior, says Arizona State University researcher Byeongkwan Ko, a recent Ph.D. graduate.Read Long Article
