Coxcomb Peak
Coxcomb Peak () is a dolerite elevation which overlooks the south end of Plumstead Valley in the Allan Hills, Victoria Land. It was reconnoitered by the New Zealand Antarctic Research Program The New Zealand Antarctic Research Programme (NZARP) was a research program that operated a permanent research facility in Antarctica from 1959 to 1996. It was created by the Geophysics Division of New Zealand's Department of Scientific and Indust ...

Dolerite
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ...

Plumstead Valley
The Allan Hills are a group of hills at the end of the Transantarctic Mountains System, located in Oates Land and Victoria Land regions of Antarctica. They are mainly ice free and about long, lying just north-west of the Coombs Hills near the heads of Mawson Glacier and Mackay Glacier. They were mapped by the New Zealand party (1957–58) of the Commonwealth Trans-Antarctic Expedition and named for Professor R. S. Allan of the University of Canterbury, New Zealand. Allan Hills is referred to as the ''Allan Nunatak'', and mapped north of Carapace Nunatak, in the memoirs of the Scott Base Leader Adrian Hayter. Both names are in the USGS listing. Meteorites According to William A. Cassidy, describing the 1976–1977 ANSMET meteorite collecting season, "Looking across the Mackay Glacier at the great sky-blue patches of ice beyond Mount Brooke, we were looking for the first time at ice that had a tremendous upstream collecting area. We were looking at Meteorite Heaven... The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand Antarctic Research Program
The New Zealand Antarctic Research Programme (NZARP) was a research program that operated a permanent research facility in Antarctica from 1959 to 1996. It was created by the Geophysics Division of New Zealand's Department of Scientific and Industrial Research (DSIR), originally based in Wellington. The programme promoted research in geochemistry, zoology, geology, botany, meteorology, and limnology. History NZARP began as a proposal by the New Zealand government, in 1953, for a research base in Antarctica. Its mission was to provide support for a variety of scientific fieldwork in Antarctica. Members worked as researchers, assistants, tour guides, operators, and administrators to Scott Base. Ground was broken for Scott Base on 10 January 1957. Assembly of the base began 12 January, conducted by the eight men who first assembled the base in Wellington, and was completed by 20 January. In 1959, the NZARP was established to work with the Ross Dependency Research Committee in the Ros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
