Permian coal beds occur within a fluvial sedimentary sequence in the Victoria Group of the Beacon Supergroup from the Ohio Range to northern Victoria Land, a 2000-km-long belt in the TransantarcticMountains, Antarctica. Although coal beds as thick as 10.7 m have been reported, most beds are thinner than 2 m. Coal beds are generally lenticular, and exposure along strike is commonly not more than 1-3 km. In northern Victoria Land the Takrouna Formation contains coal in the small North Victoria Basin; in southern Victoria Land the larger South Victoria Basin contains the Weller Coal Measures; and the southernmost and largest basin, Nimrod-Ohio Basin, from the Nimrod Glacier to the Ohio Range, contains the Buckley Formation and its equivalents. One hundred forty-four published analyses of Permian coal from this region show that ash contents range from 3.2 to almost 50% with an arithmetic mean of 15.3%, and sulfur ranges from 0.0 to 4.8% with an arithmetic mean of 0.57%. Apparent rank of the coals ranges from high-volatile C bituminous coal to anthracite, but most of the coal samples have apparent ranks of low-volatile bituminous coal and semianthracite. The relatively high rank of much of the coal of the Transantarctic Mountains probably is related both to heat and pressure from sediment load and to heat from igneous intrusion; the dominant mechanism, however, remains to be determined. Paucity of data on coal thickness and distribution dictates that coal resource estimates be assigned to the hypothetical classification. Calculations based on published geologic maps, geologic descriptions, and measured sections indicate hypothetical resources of 3 billion metric tons in the North Victoria Basin, 50 billion metric tons in the South Victoria Basin, and 100 billion metric tons in the Nimrod-Ohio Basin. "Coal Potential of Antarctica." Those authors show the localities of all major and most minor coal occurrences in Antarctica including Permian, Triassic, Jurassic (?), Cretaceous, and Tertiary coals. They summarize in tabular form the most important articles about each major area and present and discuss representative coal analyses from each area where analyses are available. Particularly useful is their bibliography of nearly a hundred references covering coal in all parts of the continent. Rose and McElroy [1987] and Whitby et al. [1983] discuss some of the difficulties and limiting factors that face any attempt to exploit coal in Antarctica. Included are a unique ecosystem, long distances to markets, and the logistic and human problems involved in maintaining a small remote settlement, as well as the technological problems of working in a cold dry climate. Problems analogous in some ways have been faced in Spitzbergen,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
