Multibeam bathymetry and magnetometer data from the Pitman fracture zone (FZ) permit construction of a plate motion history for the South Pacific over the past 65 million years. Reconstructions show that motion between the Antarctic and Bellingshausen plates was smaller than previously hypothesized and ended earlier, at chron C27 (61 million years ago). The fixed hot-spot hypothesis and published paleomagnetic data require additional motion elsewhere during the early Tertiary, either between… 
Revised Pacific-Antarctic plate motions and geophysics of the Menard Fracture Zone
A reconnaissance survey of multibeam bathymetry and magnetic anomaly data of the Menard Fracture Zone allows for significant refinement of plate motion history of the South Pacific over the last 44
A Late Miocene plate boundary reorganization along the westernmost Pacific-Antarctic ridge
Abstract Magnetic and bathymetric measurements carried out in the southwest Pacific between New Zealand and Antarctica south of 60°S, combined with the satellite-derived gravity map, add new
Geologic and kinematic constraints on Late Cretaceous to mid Eocene plate boundaries in the southwest Pacific
Abstract Starkly contrasting tectonic reconstructions have been proposed for the Late Cretaceous to mid Eocene (~ 85–45 Ma) evolution of the southwest Pacific, reflecting sparse and ambiguous data.
Plate convergence west of Patagonia and the Antarctic Peninsula since 61 Ma
Abstract A new plate kinematic model portrays plate motions immediately west and south of Drake Passage in the southeast Pacific Ocean. Overall intermediate-to-slow rate spreading generated oceanic
High‐resolution animated tectonic reconstruction of the South Pacific and West Antarctic Margin
[1] An animated reconstruction shows South Pacific plate kinematics between 90 and 45 Ma, using the satellite-derived gravity anomaly field, interpolated isochrons and plate rotation parameters from
Postspreading rifting in the Adare Basin, Antarctica: Regional tectonic consequences
Extension during the middle Cenozoic (43–26 Ma) in the north end of the West Antarctic rift system (WARS) is well constrained by seafloor magnetic anomalies formed at the extinct Adare spreading
Animated tectonic reconstruction of the Southern Pacific and alkaline volcanism at its convergent margins since Eocene times
Abstract An animated reconstruction shows South Pacific plate kinematics, in the reference frame of West Antarctica, between 55 Ma and the present-day. The ocean floor in the region formed due to
Tectonic evolution of the Pacific margin of Antarctica 1. Late Cretaceous tectonic reconstructions
We present new Late Cretaceous tectonic reconstructions of the Pacific margin of Antarctica based on constraints from marine magnetic data and regional free-air gravity fields. Results from
Cenozoic Reconstructions of the Australia-New Zealand-South Pacific Sector of Antarctica
Reconstructions are presented documenting the relative motion of the Australia. Antarctic and Pacific plates since Chron 27 (61.1 Ma). In addition to the motion of the major plates, the
Leg 197 synthesis: Southward motion and geochemical variability of the Hawaiian hotspot
The bend in the Hawaiian-Emperor volcanic chain is an often-cited example of a change in plate motion with respect to a stationary hotspot. Growing evidence, however, suggests that the bend might


Magnetic Anomalies, Bathymetry and the Tectonic Evolution of the South Pacific since the Late Cretaceous
Summary Bathymetric and magnetic anomaly data indicate that the South Pacific Ocean floor between New Zealand and Antarctica formed since late Cretaceous time by sea-floor spreading at the
A high-resolution seafloor spreading history of the South Atlantic since chron C34 is constrained by a combination of Seasat altimeter data and underway marine geophysical data. A set of 45 finite
Structural geomorphology of the eltanin fault system and adjacent transform faults of the Pacific-Antarctic plate boundary
Seabeam and SeaMARC II swath-mapping surveys, with ancillary magnetic and gravity profiling, describe the fast-slipping (84–86 mm year−1) 380 km-long Heezen transform (56° S) and the 145 km-long
Plate tectonics synthesis: The displacements between Australia, New Zealand, and Antarctica since the Late Cretaceous
Abstract A comprehensive study of the last 75 m.y. of plate tectonics history has been undertaken for the region south of 30°S in the South Pacific, Southeast Indian Ocean and the Tasman Sea. Some
Late Neogene motion of the Pacific plate
Oceanic crust between 38°S and 65°S along the Pacific-Antarctic ridge records a complete history of Neogene Pacific-Antarctic motion. We have modeled magnetic stages corresponding to portions of
Evolution of the eastern Indian Ocean since the Late Cretaceous: Constraints from Geosat altimetry
We propose a new model for the tectonic evolution of the eastern Indian Ocean from the Late Cretaceous to the present. Two types of data are used to improve previously published reconstructions.

Paleomagnetic test of the Early Tertiary Plate circuit between the Pacific Basin Plates and the Indian Plate
The internal consistency of early Tertiary reconstructions of the Pacific, Antarctic, and Indian plates has been tested by combining seafloor spreading data and paleomagnetic data. These tests show
