Description
OBSIP cruise,EW0113, Oct.27-Dec. 2, 2001 Freemantle, W. Australia. The Exmouth and Cuvier margin system represents one of the best locales to study the differences between wide versus narrow rifts and to define the interplay between strain partitioning, volcanism, segmentation, and the continent-ocean transition. We propose to conduct a geophysical expedition across the Exmouth and Cuvier magins, collecting 240-channel deep-penetration MCS data, OBS and sonobuoy refraction velocities, swath bathymetry, magnetic and gravity data, in order to investigate the tectonic, stratigraphic, and magmatic development of the region. We will determine the subsidence patterns (timing, style, magnitude, and distribution) from analysis of the pre-, syn, and post-rift stratal packages and lithofacies preserved along the Exmouth and cuvier passive margins.
