A new article published in the journal Proceedings of National Academy of Sciences (PNAS).
How much oceanic crust detaches for subducted plates? How much remains trapped within the mantle transition zone ?
We try to bring new constraints from seismic observations, and propose a new thermochemical model for the mantle.
