Reaction-enhanced permeability during serpentinite dehydration
Fluid mobilization during prograde metamorphic reactions is a poorly understood, yet crucial, phenomenon that has implications for a number of geologic problems. Here we present the first experiments to characterize permeability evolution during dehydration of a natural rock. Dehydration of serpentinite specimens resulted in the generation of pore space and the rapid development of an interconnected pore network. During breakdown of antigorite to olivine + talc + H2O, permeability increased...[Show more]
