Napier Mountains
The Napier Mountains are a group of close set peaks, the highest being Mount Elkins, at about 2,300 meters above sea level. This mountain range is located in Enderby Land, in the claimed Australian Antarctic Territory, East Antarctica. Location The Napier Mountains are roughly four degrees west of Cape Boothby, Edward VIII Bay and Edward VIII Ice Shelf, and 3.5 degrees east of Amundsen Bay. The Napier Mountains are centered about 64 km south of Cape Batterbee in Enderby Land, East Antarctica. It extends about 64 km in a NW-SE direction from Mount Codrington, and also includes Mount Kjerringa, and the Young Nunataks. Discovery The Napier Mountains were discovered in January 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson. They were named by Mawson after the Hon. Sir John Mellis Napier, a Judge of the Supreme Court of South Australia, 1924–42 and Chief Justice of South Australia, 1942–67. This mountain rang ...

Enderby Land
Enderby Land is a projecting landmass of Antarctica. Its shore extends from Shinnan Glacier at about to William Scoresby Bay at , approximately of the earth's longitude. It was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig ''Tula'', and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing. Nation state claims Subject to the constraints of the Antarctic Treaty System, the longest-held nation-state claimant rights in the territory is Australia, being a large part of its claimed Australian Antarctic Territory up to various high latitudes towards the South Pole. Features Coastal features include Amundsen Bay, Casey Bay and Cape Monakov. Mountain ranges or sub-ranges being crests above pack ice (escarpments), are the Scott Mountains, the Tula Mountains, and the Napier Mountains. The highest peak is Mount Elkins at Above Ordnance Datum (convent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ANARE
The Australian National Antarctic Research Expeditions (ANARE ) is the historical name for the Australia: Antarctic Program#Australian Antarctic program, Australian Antarctic Program (AAp) administered for Australia by the Australian Antarctic Division (AAD). History Australia has had a long involvement in South Pole, south polar regions since as early as Douglas Mawson's Australasian Antarctic Expedition in 1911. Further Australian exploration of the Antarctic continent was conducted during the British Australian and New Zealand Antarctic Research Expedition (BANZARE), which was conducted over the years 1929–1931. The Australian National Antarctic Research Expeditions were established in 1947 with expeditions to Macquarie Island and Heard Island. In 1948 the Australian Antarctic Division (AAD) was established to administer the expedition program. ANARE Name The name ANARE fell out of official use in the early 2000s. However current and former Australian Antarctic expedit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphism
Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of , and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. Metamorphism is distinct from weathering or diagenesis, which are changes that take place at or just beneath Earth's surface. Various forms of metamorphism exist, including regional, contact, hydrothermal, shock, and dynamic metamorphism. These differ in the characteristic temperatures, pressures, and rate at which they take place and in the extent to which reactive fluids are involved. Metamorphism occurring at increasing pressure and temperature conditions is known as ''prograde metamorphism'', while decreasing temperature and pressure characterize ''retrograde metamorphism''. Metamorphic petrology is the study of metamorphism. Metamorphic petrologists re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrane
In geology, a terrane (; in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or " sutured" to crust lying on another plate. The crustal block or fragment preserves its own distinctive geologic history, which is different from that of the surrounding areas—hence the term "exotic" terrane. The suture zone between a terrane and the crust it attaches to is usually identifiable as a fault. A sedimentary deposit that buries the contact of the terrane with adjacent rock is called an overlap formation. An igneous intrusion that has intruded and obscured the contact of a terrane with adjacent rock is called a stitching pluton. Older usage of ''terrane'' simply described a series of related rock formations or an area having a preponderance of a particular rock or rock groups. Overview A tectonostratigraphic terrane is not necessarily an independent microplate in origin, since it may not contain the full thickness ...

Wilkinson Peaks
The Wilkinson Peaks, also known as Langnabbane, is a group of peaks in the Napier Mountains standing southeast of Mount Griffiths and northeast of Mount Elkins in Enderby Land.

They were visited in 1961 by an ANARE (Australian National Antarctic Research Expeditions) sledge party and renamed by the Antarctic Names Committee of Australia (ANCA) for Brian Geoffrey Wilkinson, the assistant diesel mechanic at Mawson Station The Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD).
