Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

These larger grains and subsequent older structures also imply that they are not involved in the convection or flow of the mantle, meaning that the mantle may not be as well-mixed as we first thought.

Whether convection ... mantle processes couples melting-induced differentiation and trace-element partitioning, convective mixing or segregation, and mineral physics information on rock physical ...

Therefore, they do not take part in mantle convection (the flow in the Earth's mantle). Thus, contrary to what the geography books teach us, the mantle cannot be well-mixed either. Talavera-Soza ...
