Fluid flow patterns through impermeable rocks where flow is controlled by faults and fractures can be complex. In accretionary prisms, the principal driving mechanism for flow is rapid burial that results in seaward-directed fluid flow. DiLeonardo et al. (2002) explored the potential for flow oblique to convergence along the décollement zone in the toe area of the northern Barbados Ridge accretionary prism. Using various seismic reflection data volumes to investigate basement-controlled strike-slip faults below the décollement, they inferred an ENE grain defined by faults that propagate upward from the ocean crust but then largely become detached at the décollement. Although...
