Carbonate melts under lower mantle conditions
文献摘要：
Carbonate melts at high pressure and temperature conditions are crucial to the deep carbon cycle and play critical roles in the dynamics and evolution of Earth's mantle.Melting of carbon-bear-ing rocks,which generates carbonatitic and carbonated silicate melts in the mantle,has been suggested as the primary agents for the outgassing of carbon from Earth's interior dictating the deep carbon cycle.Crystalline carbonates containing tetrahedral or 3+1 coordinated carbon under high-pressure conditions have been predicted by theoretical calculations and confirmed by exper-iments,with important implications to both the storage and out-gassing of carbon in Earth's lower mantle[1].Also pressure induced transformation from 3-fold to 4-fold carbon-oxygen coor-dination has been reported in carbonate glass[2].However,the existence of tetrahedral carbon in carbonate melts under lower mantle conditions is still not clear since high temperature may dis-sociate the structure.
