Reaction-induced rheological weakening enables oceanic plate subduction

Plate subduction initiation requires weak boundaries between tectonic plates, but how weaknesses develop is unclear. Here, using high-pressure friction experiments on peridotite gouge material, the authors show that hydration reactions contribute to the weak mantle shear zones leading to subduction...
