The Eucla Basin is an artesian depression located in Western Australia and South Australia. The onshore-offshore depression covers approximately 1,141,000 km2 and slopes southward to an open bay known as the Great Australian Bight.[1]
It extends more than 500 km offshore and about 350 km inland from the coastline. The Eucla Basin is a Cenozoic basin consisting mostly of carbonate sediments and sedimentary rocks. The basin contains a sandstone aquifer at its base (confined), and an unconfined limestone aquifer.
The surface area of the basin (and Nullarbor Plain) consists mostly of grazing and rangeland, but nickel and gold are mined at the western end. Very few people live in this part of the country, with most of the region having fewer than one inhabitant per km2. In normal years, the area receives less than 250 mm of precipitation. Due to a shortage of regional seals and source rocks, the basin has poor petroleum prospects, but it is forming as a major zircon producing area, and includes the Cyclone Zircon Project.
^The term 'Eucla Basin' was first used by H.Y. L. Brown ( see: - Brown, H. Y. L. (Henry Yorke Lyell); South Australia. Parliament. House of Assembly (1885), Report on geological character of country passed over from Port Augusta to Eucla, Govt. Printer, retrieved 5 April 2012 ) on a geological map of South Australia that was published in 1900 - see page 12, of Lowry, D. C.
