The Antarctandes (Antartandes in Spanish), also known as the Antarctic Peninsula cordillera,[1] is the mountain range that is located on the northern Antarctic Peninsula, in the Graham Land and Palmer Land regions of Antarctica and may also be considered to extend across the continent.

Geology

Some geologists consider the Antarctandes a southernmost continuation of the Andes Range System on Antarctica. According to this theory the Andes start at the border between Colombia and Venezuela; run along western South America; submerge into the Atlantic Ocean to the east of Tierra del Fuego to form the underwater Scotia Arc mountain range; resurface periodically in the Shag Rocs, South Georgia and the South Sandwich Islands, South Orkney Islands and South Shetland Islands; and finally resurface on the northern Antarctic Peninsula. Chile calls the peninsula Tierra de O'Higgins, and Argentina Tierra de San Martín.

Geography

The highest mountain of the Peninsular Antarctandes is Mount Hope (3,239 m) in the Eternity Range in Palmer Land.[2]

To the southwest, the Antarctandes continue as the Ellsworth Mountains, the highest mountain range in Antarctica and much-covered by glaciers in Palmer Land; then through the Whitmore Mountains to the Queen Maud Mountains. From there, the Antarctandes follow the western coast of the Ross Sea to Cape Adare. The major transcontinental Transantarctic Mountains System shares the Cape Adare to Queen Maud ranges with the Antarctandes but then veers east along the eastern coast of the Weddell Sea. To the southeast of the Antarctic Peninsula, the Antarctic Plateau extends to the South Pole. The Antarctandes thus form a serpentine arc, over 5,000 kilometres long, along the southern rim of the Pacific Ring of Fire.

The Peninsular Antarctandes range is claimed by Argentina for Argentine Antarctica, Chile for Chilean Antarctic Territory, and the United Kingdom for the British Antarctic Territory. All these claims are frozen by Article 4 of the 1960s Antarctic Treaty System.

Antartandes es el nombre que recibe el conjunto de cadenas montañosas que sirve de eje a la península Antártica y que algunos geólogos consideran como continuación de la cordillera de los Andes en el continente antártico. De acuerdo con esta teoría, los Andes se inician en la frontera entre Colombia y Venezuela y se sumergen en el océano Atlántico al este de Tierra del Fuego formando la cordillera submarina llamada dorsal del Scotia, reapareciendo de a trechos en las islas Aurora, Georgias del Sur, Sandwich del Sur, Orcadas del Sur y Shetland del Sur, continuando luego en la península Antártica. La Antartandes se encuentra en un área en donde convergen los reclamos territoriales de Argentina (Antártida Argentina), Chile (Territorio Chileno Antártico) y el Reino Unido (Territorio Antártico Británico), por lo que la teoría que los vincula con América del Sur es de aceptación general en Argentina y Chile.

[fr] Antarctandes

Les Antarctandes, en espagnol Antartandes, sont une chaîne de montagnes d'Antarctique qui constituent les reliefs de la péninsule Antarctique. Elles se trouvent dans le prolongement de l'arc des Antilles australes au nord et des monts Ellsworth au sud. Elles doivent leur nom au fait qu'elles constituent le prolongement de la cordillère des Andes en Antarctique[réf. souhaitée].

[it] Antartande

Le Antartande, conosciute anche come cordigliera della Penisola Antartica,[1] sono una catena montuosa situata sull'asse della penisola Antartica, da molti ritenuta essere la continuazione della cordigliera della Ande nel continente antartico. Stando a questa teoria, la cordigliera della Ande, che inizia al confine tra Colombia e Venezuela, si inabissa nell'Oceano Atlantico a est della Terra del Fuoco formando l'Arco di Scotia, una catena montuosa sottomarina che affiora in alcuni punti dando origine così ad un arco insulare (tra queste isole vi sono l'arcipelago della Georgia del Sud, nella parte settentrionale, le isole Sandwich Australi, nella parte orientale, e le isole Orcadi Meridionali, nella parte meridionale) per poi riemergere e continuare nella penisola Antartica per circa 1200 km.

Антарктанды, или Антарктические Анды[1] — горная система, расположенная на Антарктическом полуострове. Представляют собой зону мезозойско-кайнозойской складчатости, связанную единством происхождения с южноамериканскими Андами. От последних Антарктанды отделяет море Скоша, возникшее в начале олигоцена[2].
