The Antarctic plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau, and some remote islands in the Southern Ocean and other surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea ), the Antarctic plate began moving the continent of Antarctica south to its present ...
Glaciation began at the end of the Devonian period (360 Ma) as Gondwana became centered on the South Pole and the climate cooled, though flora remained. During the Permian period the plant life became dominated by fern-like plants such as Glossopteris, which grew in swamps. Over time these swamps became deposits of coal in the Transantarctic ...
The high, flat, and cold environment of the Antarctic Plateau at Dome C Surface of Antarctic Plateau, at 150E, 77S. The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about 1,000 kilometres (620 mi), and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station.
During the Late Cretaceous exhumation, the Antarctic plate was extended east and west due to low-angle faulting. Seafloor spreading and propagation of the Adare Trough into the continental crust (East Antarctic craton) at the rift zone caused a rise in the East Antarctic lithosphere during the early Cenozoic exhumation.

The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent , located in the Earth 's southern hemisphere , is centered asymmetrically around the South Pole and largely south of the Antarctic Circle .
Retroarc thrusting also occurred at this time. Both events were most likely caused by the incipient subduction of the south-east Pacific Plate under the Gondwana supercontinent. As a result, marginal basin clastics from the Pacific plate's oceanic basement were obducted onto the continental margin of Gondwana, composed of older crystalline ...

Bathymetry of the Kerguelen Plateau Location of the plateau – the white spot is Kerguelen Island. The Kerguelen Plateau (/ ˈ k ɜːr ɡ əl ən /, / k ər ˈ ɡ eɪ l ən /), [1] also known as the Kerguelen–Heard Plateau, [2] is an oceanic plateau and large igneous province (LIP) located on the Antarctic Plate, in the southern Indian Ocean.
