| Abstract: | Abstract The results of thermodynamic calculations in the FeO-MgO-SiO2 (FMS) system show that the elastic properties and density across the 400-km discontinuity might be consistent with a transition zone of isochemical pyrolite composition and do not require chemical stratification. However, phase changes in pyrolite do not explain the 650-km discontinuity. |
