Which weathering product accumulates from convergent plate subduction?

💡 Explanation

Serpentinization emerges because hydration of mantle rocks forms serpentine minerals. High pressure changes from weathering drive metamorphic reactions; therefore serpentine, rather than granite, forms on the overriding plate, rather than magma upwelling.
