The global mid-ocean-ridge system is characterized by several regional-scale depth and geochemical anomalies. A prominent depth discontinuity between the East Pacific Rise and the Pacific-Antarctic Rise also coincides with a geochemical discontinuity that has been suggested by previous workers to in...
