Cenozoic geology and regolith (Shaw 1968). In McDILLS, the Etingambra Formation is up succession established in the Lake Eyre Basin in South to 12 m thick (Stewart 1968). It is composed of sandstone, Australia extends well into the Northern Territory. with subordinate siltstone and irregular beds and lenses of ¿ne conglomerate containing poorly to moderately rounded NORTHERN NT clasts. The sandstone is medium to coarse grained, poorly bedded and often friable. Wells et al (1967) described the South Alligator Valley succession as a Àuvial deposit. The Etingambra Formation is equivalent to the Eyre In the South Alligator 9alley in the north of the NT, Formation, and therefore it appears that the stratigraphic Urangesellschaft Australia Ltd (Urangesellschaft) has NORTHERN TERRITORY Tennant Creek Townsville QUEENSLAND Barkly Homestead Ranken River Roadhouse Warrabri Basin Mount Isa Willowra Basin Georgina River Yuendumu Ti-Tree Winton Witcherry Bundey Basin Basin Basin Boulia Plenty River Atula Lake Lewis Waite Basin Old Cork Basin Basin Longreach Papunya Basin Alice Springs Arema Basin Diamantina River Hale River Todd River Farm Basin Hay River Springvale Basin Hermannsburg Santa Teresa Basin Creek Thompson River Barcoo River Ayers Rock Erldunda Eyre Finke River Windorah Basin Lake Eyre Basin Birdsville Hamilton Basin Oodnadatta Innamincka Cooper Creek Callabonna Sub-basin Strzelecki Creek Marree SOUTH AUSTRALIA Billa Kalina Basin Tarkaroolo Sub-basin NEW SOUTH WALES 0 250 500 km Torrens Basin VICTORIA Adelaide Adelaide town locality drainage Palaeogene–Neogene basin, palaeovalley road State boundary endorheic lake Lake Eyre Basin, present-day catchment A13-184.ai Figure 42.17.
