The area mapped lies in the southern part of the Northern Territory and in Western Australia between latitudes 23 °S. and 26°S. and longitudes 127°30'E. and 136°30'E. (Pis 45, 46). It is 575 miles long and 205 miles wide and occupies 118,000 square miles. Sedimentary rocks of the Amadeus Basin crop out over an area of about 60,000 square miles; the remainder of the area is underlain by basement rocks or sedimentary rocks of the Great Artesian Basin in the southeast and of the Canning Basin in the west. The mapping of the Amadeus Basin by the Bureau of Mineral Resources was completed in 1964. The basin was mapped in stages: Joklik and others in 1949-51; Prichard, Quinlan, and others in 1956; Wells, Forman, Ranford, and others in 1960-64. The results of these surveys have been published by Joklik (1955), Prichard, Quinlan (1962), Wells et al. (1964, 1965, 1966, 1967), Ranford et al. (1966), Forman (1966c), and Forman et al. (1967). This Bulletin is a summary and synthesis of the entire survey. Figure 1 shows the areas covered by the various publications; previous investigations have been described in detail in them, and only an outline of earlier work in the region is given here.
