Fission Wall
Fission Wall () is a granite cliff, high, on the north face of Mount Griffith, Hays Mountains, in the Queen Maud Mountains of Antarctica. The feature was climbed on November 16, 1987, by a United States Antarctic Research Program – Arizona State University geological party led by Edmund Stump Edmund is a masculine given name or surname in the English language. The name is derived from the Old English elements ''ēad'', meaning "prosperity" or "riches", and ''mund'', meaning "protector". Persons named Edmund include: People Kings and ....

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Mount Griffith
Mount Griffith () is a mountain, standing north-northeast of Mount Vaughan in the Hays Mountains of the Queen Maud Mountains of Antarctica. It was first observed and roughly mapped in December 1929 by the Byrd Antarctic Expedition (ByrdAE) geological party under Laurence Gould. It was remapped in December 1934 by the ByrdAE geological party under Quin Blackburn, and named by Richard E. Byrd for Raymond Griffith of Twentieth Century-Fox 20th Century Studios, Inc. (previously known as 20th Century Fox) is an American film production company headquartered at the Fox Studio Lot in the Century City area of Los Angeles. As of 2019, it serves as a film production arm of Walt Disn ... Pictures, who assisted in assembling motion-picture records of the expedition.

Hays Mountains
The Hays Mountains () are a large group of mountains and peaks of the Queen Maud Mountains of Antarctica, surmounting the divide between the lower portions of Amundsen Glacier and Scott Glacier and extending from the vicinity of Mount Thorne on the northwest to Mount Dietz on the southeast. They were discovered by Rear Admiral Richard E. Byrd on the South Pole flight of November 28–29, 1929, and mapped in part by the Byrd Antarctic Expedition geological parties to this area in 1929 and 1934. They were named by Byrd for Will H. Hays, former head of the Motion Picture Producers and Distributors of America. Key features Mount Astor, a prominent peak in the range, was named by Byrd for Vincent Astor, of the Astor family, for his philanthropic contributions to the 1929 expedition. Features Geographical features include: * Cappellari Glacier * Cox Peaks * Dragons Lair Névé * Fission Wall * Forbidden Valley * Heinous Peak * Koerwitz Glacier * Mount Armstrong * Mount Astor * M ...

Queen Maud Mountains
The Queen Maud Mountains are a major group of mountains, ranges and subordinate features of the Transantarctic Mountains, lying between the Beardmore and Reedy Glaciers and including the area from the head of the Ross Ice Shelf to the Antarctic Plateau in Antarctica. Captain Roald Amundsen and his South Pole party ascended Axel Heiberg Glacier near the central part of this group in November 1911, naming these mountains for the Norwegian queen Maud of Wales. Despite the name, they are not located within Queen Maud Land. Elevations bordering the Beardmore Glacier, at the western extremity of these mountains, were observed by the British expeditions led by Ernest Shackleton (1907–09) and Robert Falcon Scott (1910-13), but the mountains as a whole were mapped by several American expeditions led by Richard Evelyn Byrd (1930s and 1940s), and United States Antarctic Program (USARP) and New Zealand Antarctic Research Program (NZARP) expeditions from the 1950s through the 1970s.

United States Antarctic Research Program
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

Fission Track Dating
Fission track dating is a radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium-bearing minerals and glasses. Fission-track dating is a relatively simple method of radiometric dating that has made a significant impact on understanding the thermal history of continental crust, the timing of volcanic events, and the source and age of different archeological artifacts. The method involves using the number of fission events produced from the spontaneous decay of uranium-238 in common accessory minerals to date the time of rock cooling below closure temperature. Fission tracks are sensitive to heat, and therefore the technique is useful at unraveling the thermal evolution of rocks and minerals. Most current research using fission tracks is aimed at: a) understanding the evolution of mountain belts; b) determining the source or provenance of sediments; c) studying the thermal evolution of basins; d) determinin ...

Cliffs Of The Ross Dependency
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
