Graphite Peak
Graphite Peak () is a peak, high, standing at the northeast end of a ridge running northeast from Mount Clarke, just south of the head of Falkenhof Glacier in Antarctica. It was so named by the New Zealand Geological Survey Antarctic Expedition (1961–62) because of the graphite Graphite () is a crystalline form of the element carbon.

Mount Clarke (Antarctica)
The Barton Mountains () are a group of mountains located south of the Commonwealth Range and the Hughes Range and bounded by Keltie Glacier, Brandau Glacier, Leigh Hunt Glacier, and Snakeskin Glacier, in the Queen Maud Mountains. Exploration and naming The Barton Mountains were mapped by the United States Geological Survey (USGS) from surveys and from United States Navy aerial photographs, 1958–63. They were named by the Advisory Committee on Antarctic Names (US-ACAN) after Lieutenant Commander Walter H. Barton, U.S. Navy, officer in charge of the Squadron VXE-6 detachment at Beardmore South Camp in the 1985–86 field season. Lieutenant Commander Barton developed, coordinated, and executed the logistical plan for this large and remote camp, which was in operation for 78 days and required over 800 flight hours in support of research in the Beardmore Glacier area. Location The Barton Mountains lie to the south of the point where the Brandau Glacier enters the Keltie Glacier fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falkenhof Glacier
Keltie Glacier is a large Antarctic glacier, long, draining from Pain Névé southwest around the southern extremity of the Commonwealth Range, and then northwest to enter Beardmore Glacier at Ranfurly Point. It was discovered by the British Antarctic Expedition, 1907–09, under Ernest Shackleton, who named it for Sir John Scott Keltie Sir John Scott Keltie (29 March 1840 – 12 January 1927) was a Scottish geographer, best known for his work with the Royal Geographical Society. History Keltie was born in Dundee and attended school in Perth. He matriculated at the Unive ..., Secretary of the Royal Geographical Society, 1892–1915.

New Zealand Geological Survey Antarctic Expedition
The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active throughout the 1950s and 1960s. Features named by the expeditions 1957–1958 expedition The 1957–1958 expedition went to the Ross Dependency and named the Borchgrevink Glacier. Other features named include: * Carter Ridge * Felsite Island * Halfway Nunatak * Hedgehog Island * Moraine Ridge 1958–1959 expedition * Cadwalader Beach * Cape Hodgson * Carter Ridge * Isolation Point * Mountaineer Range * Mount Aurora * Mount Hayward * Mount Henderson (White Island) * Mount Bird. 1960–1961 expedition * Deverall Island * Lonewolf Nunataks 1961–1962 expedition * Aurora Heights * The Boil * Ford Spur * Graphite Peak * Half Century Nunatak * Half Dome Nunatak * Hump Passage * Last Cache Nunatak * Lookout Dome * Montgomerie Glacier * Mount Fyfe * Mount Macdonald * Snowshoe Pass * Turret Nu ...

Graphite
Graphite () is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. Under high pressures and temperatures it converts to diamond. It is a weak conductor of heat and electricity. Types and varieties Natural graphite The principal types of natural graphite, each occurring in different types of ore deposits, are * Crystalline small flakes of graphite (or flake graphite) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken. When broken the edges can be irregular or angular; * Amorphous graphite: very fine flake graphite is sometimes called amorphous; * Lump graphite (or vein graphite) occurs in fissure veins or fractures and appears as massive platy intergrowths of fibrous or acicular crystalline ...

Mountains Of The Ross Dependency
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
