Geophysical and geological surveys in and around the Princess Elizabeth Trough, East Antarctica, weie carried out in the 1998-99 austral summer season The survey area covers the Princess Elizabeth Trough, the southern margin of the Kerguelen Plateau, and the Bruce Plateau Magnetic lineations, which were tentatively identified as anomalies Ml2 to M10, were recognized on the abyssal plain in the Princess Elizabeth Trough Six seismic sequences (A to F) are recognized in the Princess Elizabeth Trough and north of the Bruce Plateau On the southern Kerguelen Plateau, five seismic sequences (KP1 to KP5) are recognized The geological time of the seismic sequences was estimated based on correlation with lithostratigraphic results of ODP Site 738 and relationship to tectonic history in this area The geological times of the sequences are as follows Sequence F on the continental rise is a pre-rift sequence that was deposited in late Jurassic or older time On the abyssal plain in ihe Princess Elizabeth Trough, where magnetic hneations are observed, sequence F consists of oceanic crusts and was formed in the Early Cretaceous Sequence E is a syn-nft sediment formed during late Jurassic to Early Cretaceous time Sequence D is a post-rift sediments formed in the Early Cretaceous Sequence C was deposited with marine transgression, which occurred with regional crustal subsidence accompanying the subsidence of the southern Kerguelen Plateau after approximately 90 Ma Sequences C and B are correlated with sediments formed during Late Cretaceous to middle Eocene time and sediments forrred after the middle Eocene, respectively Sequence A is sediments formed during early Miocene to Quaternary time
