This paper describes a transregional structural discontinuity extending along latitude 25°S in Australia interpreted from the "Free-Air Gravity Anomaly Map of the World" (Bowin et al., 1982). The Amadeus Basin in Central Australia, enclosed between the Musgrave and Arunta blocks, is located along that latitudinal structure. The pattern of free-air gravity anomalies also reveals three east-west trending structures parallel to the 25°S discontinuity. A major intersection of structures trending E-W, N-S, NW and NE has been identified in the westernmost part of the Musgrave block, characterized by high gravity values. This area is considered to have potential for concentration of metals, especially nickel and cobalt.
