Part 5. Plate boundary evolution in the New Guinea region: Plate model for late Cainozoic volcanism at the southern margin of the Bismarck Sea, Papua New Guinea

Abstract

Two Late Cainozoic volcanic arcs can be recognised at the southern margin of the Bismarck Sea, Papua New Guinea. Both arcs provide striking examples of the geodynamic complexity to be expected in regions characterised by small plates whose instantaneous poles of rotation are nearby (cf. Krause, 1973).
