Abstract

extended CO2 carbonates amorphization carbon dioxide pressure‐induced ionization deep carbon cycle
Under pressure: An increase in the ionic character in CO bonds at high pressures and temperatures is shown by the chemical/phase transformation diagram of CO2 (see picture). The presence of carbonate carbon dioxide (i‐CO2) near the Earth′s core–mantle boundary condition provides insights into both the deep carbon cycle and the transport of atmospheric CO2 to anhydrous silicates in the mantle and iron core.
