Eurasian Basin Eurasian Basin The Eurasia Basin, or Eurasian Basin, is one of the two major basins into which the Arctic Basin of the Arctic Ocean is split by the Lomonosov Ridge (other being the Amerasia Basin). The Eurasia Basin may be seen as an extension of the North Atlantic Basin through Fram Strait. It is further split by the mid-ocean Gakkel Ridge into the Nansen Basin and the Amundsen Basin. The latter basin is the deepest one of the Arctic Ocean and the geographic North Pole is located there. The Eurasia Basin is bounded by Greenland, the Lomonosov Ridge, and the
Sydney Basin offshore with under water depths of up to . Another Australian Government agency classifies that the basin covers approximately . The Sydney Basin is part of a major basin system that extends over from the Bowen Basin in Queensland through to the Basin in NSW. Onshore, the basin contains of Permo-Triassic clastic sediments, while the offshore basin contains of sediments. The basin overlies the Lachlan Fold Belt and Late Carboniferous volcanoclastic sediments. The basin formed during extension in the Early Permian, with half-graben infilled with the Dalwood and Talaterang Groups. Foreland loading followed with the compression of the Currarong Orogen
