Larter British Antarctic Survey, High Cross, Madingley Road, Cambridge, CB3 0ET, UK [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 both published and new work on marine geophysical data. The Great South Basin and Bounty Trough, New Zealand, are shown as the earliest Pacific–Antarctic plate boundary that opened before 83 Ma. The earliest true Pacific–Antarctic seafloor formed within the eastern parts of this boundary, but later and farther west, seafloor formed within its Antarctic flank. After 80 Ma, the Bellingshausen plate converged with an oceanic part of the Antarctic plate to its east, while its motion simultaneously caused rifting in continental Antarctica to the south. The Pacific–Bellingshausen spreading center developed a set of long offset transform faults that the Pacific–Antarctic plate boundary inherited around chron C27 when the Bellingshausen plate ceased to move independently as part of a Pacific- wide plate tectonic reorganization event. -

Geology: Seismic and Gravity Data Reveal Tertiary Interplate Subduction in the Bellingshausen Sea, Southeast Pacific
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Electronic Publication Information Center Seismic and gravity data reveal Tertiary interplate subduction in the Bellingshausen Sea, southeast Pacific Karsten Gohl* Frank Nitsche Heinz Miller Alfred Wegener Institute for Polar and Marine Research, P.O. Box 120161, D-27515 Bremerhaven, Germany ABSTRACT Satellite gravity data reveal extraordinary lineations in the gravity field of the western Bell- ingshausen Sea. Major north-south–striking gravity anomalies west of Peter I Island and be- tween the island and the De Gerlache Seamounts raise questions of the deep crustal structure and tectonic events in that part of the Antarctic plate. As part of two cruises in the Bellingshausen and Amundsen seas with RV Polarstern in 1994 and 1995, we acquired multichannel seismic records and shipborne gravity data across the gravity anomalies. The combined data set shows strong ev- idence for a converging event within the oceanic crust, including a subducted crustal segment and possibly accreted sediments on top of the downgoing basement. West and east of the basement step and diffraction zone, the seismic sections indicate normally developed oceanic crust with moderate basement undulations. The sequence of undisturbed sediments on top of the compres- sional structure suggests a tectonic event between 50 and 13 Ma, while relative motion between the Antarctic-Bellingshausen plate and the Phoenix plate had already begun in the Late Creta- ceous. We suggest that this convergent tectonic structure could have developed as an early Ter- tiary transcurrent plate boundary to accommodate the relative motion between the Antarctic- Bellingshausen plate and the southward migrating and subducting Phoenix plate. -

Highly accurate, vertical deflection profiles (1-2 Jlrad), derived from 22 repeat cycles of Geosat altimetry, reveal subtle lineations in the gravity field associated with the South Pacific fracture zones. These fracture zone lineations are correlated with sparse shipboard bathymetric identifications of fracture zones and thus can be used to determine paleo-spreading directions in uncharted areas. The high density of Geosat altimeter profiles reveals previously unknown details in paleo-spreading directions on all of the major plates. Magnetic anomaly identifications and magnetic lineation interpretations from published sources were combined with these fracture zone lineations to produce a tectonic fabric map. Tne tectonic fabric was then used to derive new plate reconstructions for twelve selected times in the Late Cretaceous and Cenozoic. -
Late Cretaceous to Early Tertiary Subduction History of the Antarctic Peninsula
Journal of the Geological Society, London, Vol. 155, 1998, pp. 255–268. Printed in Great Britain. Late Cretaceous to early Tertiary subduction history of the Antarctic Peninsula JOE J. McCARRON1,2 & ROBERT D. LARTER1 1British Antarctic Survey, High Cross, Madingley Road, Cambridge CB3 0ET, UK (e-mail: [email protected]) 2Present address: Companias Shell de Colombia, c/o Expat Mail, Postbus 245, 2501 CE Den Haag, The Netherlands Abstract: Quantitative estimates of the rates and azimuths of Phoenix plate convergence with the Antarctic Peninsula have been derived from plate rotation calculations for two periods in the Late Cretaceous and early Tertiary (83.0–67.7 and 61.1–53.4 Ma). Published marine magnetic anomaly identifications and ‘flow lines’ interpreted from gravity anomaly maps were used in simple spherical geometry calculations to derive Phoenix–Pacific stage rotations. These were combined with published Pacific–Antarctic rotation data to determine contemporaneous Phoenix–Antarctic stage rotations. The results indicate a significant change in azimuths of relative motion between the Late Cretaceous and early Tertiary. Late Cretaceous, and perhaps earlier, oblique subduction probably caused migration of fore-arc slivers along the margin, resulting in variations in width of the accretionary prism. Comparison between synthetic magnetic profiles and a 900 km long magnetic profile across ocean floor produced at the Antarctic–Phoenix ridge during the early Tertiary establishes the time of a major decrease in spreading rate, and hence also in convergence rate, as chron C23r (52.3 Ma). The associated change in subduction dynamics may have caused the dextral transtensional deformation observed in the George VI Sound region and initiated uplift of blueschist facies rocks now exposed on Smith Island.
