| Abstract: | Geodynamic studies have shown that mantle convection is like a giant blender to make the original heterogeneous mantle mixing and homogenizing. However,some models,especially from geochemical data show that the modern mantle may still contain a number of reservoir bodies with different chemical composition. Then,the modern mantle is homogeneous? Authors have defined a box replacement degree of convective mantle mixing and pervasion degree of convective mantle mixing (that equals to initial density of tracin... |
