남극 대륙은 원생누대, 고생대, 중생대, 신생대에 걸쳐서 지질학적인 발전 과정을 거쳐 왔다. 1억 7천만년 전, 남극 대륙은 당시 초대륙이었던 곤드와나 대륙의 일부였다. 남극 대륙이 지금과 같은 모습을 갖추게 된 것은 약 35Ma 전의 일이었다.

Ab diesem Äon entwickelte sich das Grundgebirge, dessen Kratone bzw. kratonisierte Krustenblöcke zeitlich bis Paläoproterozoikum weiterreichen.Ostantarktika nahm eine Zentralposition während der Formierung und dem Zerfall von verschiedenen Kontinenten und Superkontinenten ein, vermutlich beginnend mit dem hypothetischen ersten Superkontinent Ur. Verlässlichere Nachweise sind seit Rodinia und Gondwana, insbesondere Ostgondwana vorhanden. In letzteren hatte Ostantarktika tektonischen Kontakt mit Groß-Indien (Indischer Subkontinent, Madagaskar, Seychellen, Sri Lanka), Teilen von Australien und Afrika, wodurch sich am Kontinentalrand zwischen dem Mesoproterozoikum und dem Paläozoikum mehrere gebirgsbildende Prozesse ereigneten. Diese erzeugten orogene Gürtel. Die letzte große Gebirgsbildung fand zwischen dem ausgehenden Mesozoikum und dem Paläogen statt. Auf dem Grundgebirge und den orogenen Gürteln lagerte sich regional ein paläozoisches bis mesozoisches Deckgebirge ab. Nach der Separierung des Teilkontinents Ostantarktikas im Mesozoikum ist dieser umgeben einerseits vom heutigen Südlichen Ozean mit seinen Nebenmeeren und andererseits vom Transantarktischen Gebirge. Dieses bildet die geologische Grenze zu Westantarktika. Zusammen mit Ostantarktika formen sie den Kontinent Antarktika. Seit dem mittleren Eozän ist Ostantarktika bzw. ganz Antarktika größtenteils vom antarktischen Eisschild bedeckt. Nur kleinere Aufschlüsse ragen am Kontinentalrand aus der Eisbedeckung hervor und können direkt untersucht werden. Die übrigen subglazialen Bereiche wurden/werden mittels Fernerkundung erforscht.

, The geology of Antarctica covers the geolo … 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. However, techniques such as remote sensing have begun to reveal the structures beneath the ice. Geologically, West Antarctica closely resembles the Andes of South America. The Antarctic Peninsula was formed by uplift and metamorphism of sea-bed sediments during the late Paleozoic and the early Mesozoic eras. This sediment uplift was accompanied by igneous intrusions and volcanism. The most common rocks in West Antarctica are andesite and rhyolite volcanics formed during the Jurassic Period. There is also evidence of volcanic activity, even after the ice sheet had formed, in Marie Byrd Land and Alexander Island. The only anomalous area of West Antarctica is the Ellsworth Mountains region, where the stratigraphy is more similar to the eastern part of the continent. The West Antarctic Rift System, a major active rift valley, lies between West and East Antarctica. Its major phase of rapid, broad extension occurred in Cretaceous time, and involved the action of both normal and strike slip faults within West Antarctica and contiguous Zealandia. The rift is still active with slow movement of West Antarctica away from East Antarctica. East Antarctica is geologically very old, dating from the Precambrian, with some rocks formed more than 3 billion years ago. It is composed of a metamorphic and igneous platform which is the basis of the continental shield. On top of this base are various more modern rocks, such as sandstones, limestones, coal and shales laid down during the Devonian and Jurassic periods to form the Transantarctic Mountains. In coastal areas such as Shackleton Range and Victoria Land some faulting has occurred. More than 170 million years ago, Antarctica was part of the supercontinent Gondwana. Over time Gondwana broke apart and Antarctica as we know it today was formed around 35 million years ago.ay was formed around 35 million years ago.

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. However, techniques such as remote sensing have begun to reveal the structures beneath the ice. More than 170 million years ago, Antarctica was part of the supercontinent Gondwana. Over time Gondwana broke apart and Antarctica as we know it today was formed around 35 million years ago.ay was formed around 35 million years ago.
