文摘
- •
Plate bending does not create sufficiently negative dynamic pressure to promote mantle hydration.
- •
Available geophysical observations can be interpreted in terms of crack-like porosity, instead of alteration.
- •
The occurrence of lower-plane earthquakes requires an insignificant amount of water in the slab mantle.
