Understanding subduction infancy to mature subduction in Southwest Japan via the self‑consistent formation of a weak slab interface
초록: The weak slab interface controls long‐term subduction dynamics. A weak hydrous layer at the slab interface promotes mechanical decoupling between the forearc mantle and the subducting slab and converts a hot forearc mantle to a cold mantle. Often referred to as a cold nose, the cold forearc mantle, plays a key role in the […]
