Figure F2. Predicted topography of the northwest Pacific (Smith and Sandwell, 1997) and magnetic lineations of the western Pacific compiled from Nakanishi et al. (1989) and the PLATES Project (1998). Ages of selected lineations (solid black lines) are given using the time scale of Channell et al. (1995). Open circles show locations of selected DSDP/ODP sites. Site 1149 is located 2200 km northwest of Site 801 along a fracture zone bounded flow line spanning ~36 m.y. White dashed lines = locations of fracture zones (GMT software; Wessel and Smith, 1995).
