The geology of Antarctica covers the geological development of the continent through the Archean, Proterozoic and Phanerozoic eons. The geological study of Antarctica has been greatly hindered by the fact that nearly all of the continent is continuously covered with a thick layer of ice.
The geology of the Antarctic Peninsula occurred in three stages: Pre-subduction stage of marginal basin deposition, later separated by the Gondwanian orogeny during the Permian -Late Triassic The middle subduction phase, characterized by the formation of the Antarctic Peninsula (inner) and South Shetland Islands (outer) magmatic arcs , during ...

The Antarctic Plate. The geology of Antarctica, largely obscured by the continental ice sheet, [57] is being revealed by techniques such as remote sensing, ground-penetrating radar, and satellite imagery. [58] Geologically, West Antarctica closely resembles the South American Andes. [59]
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 ...
The Beacon Supergroup is a geological formation exposed in Antarctica and deposited from the Devonian to the Triassic). The unit was originally described as either a formation or sandstone, and upgraded to group and supergroup as time passed.
Enderby Land is a region of Northeastern Antarctica which extends into the Southern Indian Ocean. The area is claimed by Australia as part of the Australian Antarctic Territory. The unique and diverse geological features of this region have been associated with the evolution and development of the supercontinent Gondwana.
