There is considerable evidence that over long periods of time or at temperatures close to melting the crystalline mantle of the earth behaves as a fluid. Such behavior is explained by diffusion creep which gives a Newtonian viscosity. In this paper a one-dimensional fluid model is presented for the deep structure of dip-slip fault zones in island arc areas where the oceanic crust appears to be moving downwards under the adjacent continents. A strongly temperature dependent viscosity confines velocity gradients to a narrow fault zone; within this zone viscous dissipation locally heats the fluid and reduces its viscosity. Given the slip velocity across the fault zone the temperature and rates of heat production predicted are in good agreement with observations; the heat production due to viscous heating explains the volcanic activity and high surface heat flux associated with island arc areas. Taking a reasonable value for the shear stress associated with the fault zone the predicted dimensions of the fault zone and heat flux away from the fault zone are in reasonable agreement with observation.
