Under pressure : An increase in the ionic character in CO bonds at high pressures and temperatures is shown by the chemical/phase transformation diagram of CO 2 (see picture). The presence of carbonate carbon dioxide ( i ‐CO 2 ) near the Earth′s core–mantle boundary condition provides insights into both the deep carbon cycle and the transport of atmospheric CO 2 to anhydrous silicates in the mantle and iron core.
