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 Hanson Formation (also known as the Shafer Peak Formation) is a geologic formation on Mount Kirkpatrick and north Victoria Land, Ross Dependency, Antarctica.It is one of the two major dinosaur-bearing rock groups found on Antarctica to date; the other is the Snow Hill Island Formation and related formations from the Late Cretaceous of the Antarctic Peninsula.
The base of the Beacon Supergroup is marked by an unconformity and is composed of the Devonian Taylor Group, a quartzose sandstone sequence; and the Late Carboniferous to Early Jurassic Victoria Group, consisting of glacial beds, sandstone, shale, conglomerate, and coal.
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.
