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.
Nearly every aspect of science, from geology to biology and glaciology to arts, was covered but a major undercurrent ran through the conference. Antarctica is changing, faster than expected.

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 ...
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').
The Pleiades are a volcanic group in northern Victoria Land of Antarctica.It consists of youthful cones and domes with Mount Atlas/Mount Pleiones, a small stratovolcano formed by three overlapping cones, being the dominant volcano and rising 500 m (1,600 ft) above the Evans Névé plateau.
The geology of the Ellsworth Mountains, Antarctica, is a rock record of continuous deposition that occurred from the Cambrian to the Permian periods, with basic igneous volcanism and uplift occurring during the Middle to Late Cambrian epochs, deformation occurring in the Late Permian period or early Mesozoic era, and glacier formation occurring ...
Brown Bluff is a basalt tuya on the Tabarin Peninsula of northern Antarctica. [2] It formed in the last 1 million years as a result of subglacial eruptions within an englacial lake. The volcano's original diameter is thought to have been about 12–15 kilometers (7.5–9.3 mi) and was probably formed by a single vent.
