Sciences de la Terre et des Planetes332 (5)323-329ODP Leg 189 was designed to test the hypothesis that opening of the Tasmanian Seaway and initiation of circumpolar circulation contributed to the thermal isolation of Antarctica, leading to the development of initial ice-sheet and oceanic thermohaline circulation. The clay assemblages of the Tasmanian region contain the traces of two tectonic stages associated with ocean opening south of the south Tasman Rise near the Palaeocene-Eocene boundary and strike-slip activity between the western Tasmanian land-bridge and Antarctica during the Late Eocene. Earliest Oligocene clays indicate that cooling of Antarctic margins and activity of western boundary circulation progressed with the regional subsidence.completedOceanographyAntarctic OceanAntarcticaAustralasiaAustraliaCenozoicCircum-Antarctic regionclay mineralscoolingdrillingEoceneglacial geologyice sheetsIndian Oceanland bridgesLeg 189marine sedimentsocean circulationOcean Drilling Programocean openingOligocenePacific Oceanpaleo-oceanographypaleoclimatologyPaleogenesedimentssheet silicatessilicatesSouth PacificSouthwest PacificsubsidenceTasman SeaTasmania AustraliaTasmanian SeawaytectonicsTertiarythermohaline circulationWest Pacificurn:org.iodp:exp:189urnlargerWorkCitationcampaignFrenchgeoscientificInformation-180.0000180.0000-90.000025.0000AntarcticaIndian OceanTasman SeaTasmania Australia
