![]() ![]() So the carbon escaping from the liquid outer core would become diamond when it enters into the mantle." The stable form of carbon at the pressure-temperature conditions of Earth's core-mantle boundary is diamond. "Therefore, solubility of carbon, which likely exists in the Earth's core, decreases locally where hydrogen enters into the core from the mantle (through dehydration). "At the pressures expected for the Earth's core-mantle boundary, hydrogen alloying with iron metal liquid appears to reduce solubility of other light elements in the core," said Shim. However, scientists have found that much more carbon exists in the mantle than expected. "In fact, the temperature is high enough that some minerals should melt at such conditions."īecause carbon is an iron loving element, significant carbon is expected to exist in the core, while the mantle is thought to have relatively low carbon. "Temperature at the boundary between the silicate mantle and the metallic core at 3,000 km depth reaches to roughly 7,000 F, which is sufficiently high for most minerals to lose H 2O captured in their atomic scale structures," said Dan Shim, professor at ASU's School of Earth and Space Exploration. However, they found that for the conditions of the core-mantle boundary carbon comes out of the liquid iron-metal alloy and forms diamond. The researchers found that water and metal react and make iron oxides and iron hydroxides, just like what happens with rusting at Earth's surface. ![]() They conducted experiments at the Advanced Photon Source at Argonne National Laboratory, where they compressed iron-carbon alloy and water together to the pressure and temperature expected at the Earth's core-mantle boundary, melting the iron-carbon alloy. graduate, and his collaborators published their findings on the core-mantle boundary in Geophysical Research Letters. Therefore, a chemical reaction similar to rusting steel could occur at Earth's core-mantle boundary.īyeongkwan Ko, a recent Arizona State University Ph.D. The temperature at the core-mantle boundary is at least twice as hot as lava, and high enough that water can be released from the hydrous minerals. Scientists have shown that the oceanic crust that sits on top of tectonic plates and falls into the interior, through subduction, contains hydrous minerals and can sometimes descend all the way to the core- mantle boundary. The Earth's core is the largest carbon storage on Earth-roughly 90% is buried there. His music can be found at their "FIREPOWER" - "Redeemer of Souls" - "Touch Of Evil: Live" - "Nostradamus".
