Which outcome is accelerated by increased saturation during subduction?

💡 Explanation

Increased water saturation enhances mantle wedge melting because it lowers the mantle's solidus temperature via flux melting; therefore, more magma genesis occurs, rather than decreased melting associated with lower saturation.
