East Australian passive margin

Target entity: East Australian passive margin
Context triple: [Australian Plate, formsFeature, East Australian passive margin]

• A. Australian Southern Margin
  The Australian Southern Margin is a vast passive continental margin along the southern coast of Australia, characterized by extensive sedimentary basins, offshore hydrocarbon potential, and complex tectonic and stratigraphic evolution linked to the breakup of Gondwana.
• B. Southwest Indian Ocean passive margin system
  The Southwest Indian Ocean passive margin system is a broad tectonic and sedimentary region along the western Indian Ocean where the continental crust of Madagascar and nearby areas transitions into oceanic crust formed during the breakup of Gondwana.
• C. passive margin of Gondwana
  The passive margin of Gondwana was the long, tectonically quiet continental edge of the ancient supercontinent Gondwana, where thick sedimentary sequences accumulated and from which various microcontinents, such as Avalonia, later rifted away.
• D. Atlantic passive margin
  The Atlantic passive margin is a tectonically quiet continental edge along the Atlantic Ocean characterized by broad continental shelves, thick sedimentary deposits, and a lack of major active plate boundaries or significant seismic and volcanic activity.
• E. East Antarctic margin of the Southern Ocean
  The East Antarctic margin of the Southern Ocean is the remote, ice-dominated oceanic boundary fringing East Antarctica, characterized by extensive continental shelves, strong katabatic winds, and crucial roles in global ocean circulation and climate.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
