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 ...

A speculative representation of Antarctica labelled as ' Terra Australis Incognita ' on Jan Janssonius's Zeekaart van het Zuidpoolgebied (1657), Het Scheepvaartmuseum The name given to the continent originates from the word antarctic, which comes from Middle French antartique or antarctique ('opposite to the Arctic') and, in turn, the Latin antarcticus ('opposite to the north').
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. [3]
The Indian Plate and the Australian Plate are now separated by the Capricorn Plate and its diffuse boundaries. [44] During the opening of the Indian Ocean, the Kerguelen hotspot first formed the Kerguelen Plateau on the Antarctic Plate c. 118 to 95 Ma and then the Ninety East Ridge on the Indian Plate at c. 100 Ma .
