Abstract

A comparison of pore fluids and authigenic carbonates sampled by the Ocean Drilling Program from the Nankai, Peru, Barbados, and Cascadia accretionary wedges illustrates significant disequilibria in oxygen isotopes, which in some cases may be related to rapid incursions of fluids along fault conduits in the past. The required high fluid-flow rates suggest a mechanism of seismically induced fluid migration to bring fluids rapidly from depths of greater than 2 km to the surface.
