Heterogeneity in the Crust and Upper Mantle
Most of our knowledge about the physical structure and the chemical composition of the Earth''s deep interior is inferred from seismic data. The interpretation of seismic waves generally follows the assumption that the Earth''s physical structure is grossly layered and that fluctuations of the physical parameters within individual layers are smooth in structure and small in magnitude. While this v...
