Abstract:
ODP Leg 189 Site 1172, drilled in the East Tasman Plateau, has allowed documentation of the Tasman Gateway during pre-rifting and rifting of Australia from Antarctica in the Late Cretaceous and early Paleogene, and of subsequent paleo-oceanographic events. The new 2G 750R magnetometer on the JOIDES Resolution brought much of the weakly magnetized carbonate Neogene section into a measureable range, and the silstones provided reliable magnetostratigraphy for much of the earlier time interval. The record established overall average sedimentation rates of 10m/m.y. for the Maastrichtian to late Eocene siliciclastic sediments laid down as the South Tasman Rise rifted from Antarctica.
