Activation of Dissolution‐Precipitation Creep Causes Weakening and Viscous Behavior in Experimentally Deformed Antigorite

Antigorite occurs at seismogenic depth along plate boundary shear zones, particularly in subduction and oceanic transform settings, and has been suggested to control a low‐strength bulk rheology. To constrain dominant deformation mechanisms, we perform hydrothermal ring‐shear experiments on antigori...
