Abstract:
The Pacific plate has undergone a substantial northward displacement during the late Mesozoic and the Cainozoic. Here we give additional documentation for such motion based on palaeomagnetic measurements of a sequence of sedimentary and basalt samples collected from middle Oligocene to Aptian sections of Deep Sea Drilling Project (DSDP) site 289 (Andrews, 1975; 00° 29.92'S, 158° 30.69'E) drilled on the Ontong Java Plateau.
