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 frozen continent of Antarctica was the last continent humanity set foot on. The first documented landings made below the Antarctic Circle took place in 1820, when Admiral Fabian Gottlieb von Bellingshausen and the crew of the Vostok and Mirny, as part of the Russian Antarctic Expedition, made land at Peter I Island and Alexander Island.
These smaller plates are often not shown on major plate maps, as the majority of them do not comprise significant land area. For purposes of this list, a minor plate is any plate with an area less than 20 million km 2 (7.7 million sq mi) but greater than 1 million km 2 (0.39 million sq mi).
Retroarc thrusting also occurred at this time. Both events were most likely caused by the incipient subduction of the south-east Pacific Plate under the Gondwana supercontinent. As a result, marginal basin clastics from the Pacific plate's oceanic basement were obducted onto the continental margin of Gondwana, composed of older crystalline ...
The Louisville Ridge stretches diagonally across this bathymetric map of the southwest Pacific Ocean towards the Pacific-Antarctic Ridge at right bottom The Pacific-Antarctic Ridge (PAR, Antarctic Pacific Ridge, South Pacific Rise, South Pacific Ridge) [ 4 ] is a divergent tectonic plate boundary located on the seafloor of the South Pacific ...
A map of the Antarctic region, including the Antarctic Convergence and the 60th parallel south The Antarctic Plate. The Antarctic (/ æ n ˈ t ɑːr t ɪ k,-k t ɪ k /, US also / æ n t ˈ ɑːr t ɪ k,-k t ɪ k /; commonly / æ ˈ n ɑːr t ɪ k /) [Note 1] is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole.
The Transantarctic Mountains (TAM) separate East and West Antarctica. The rift system that formed them is caused by a reactivation of crust along the East Antarctic Craton. This rifting or seafloor spreading causes plate movement that results in a nearby convergent boundary which then forms the mountain range.
