%X Overview scale interpretation of the Murray?Riverina airborne magnetic and radiometric survey has revealed many bedrock features in a region covered by significant overburden. Regional Bouguer gravity data suggest basins and granitic bodies at depth. Pattern contrasts in the magnetic data contribute to a greater understanding of event timing and define numerous covered features, including granitic bodies, two areas of intrusive pipe-like clusters, possible extension basins of the Oaklands Basin and numerous mineral sand strand lines and their re-deposition as ``lunettes'. Radiometric data in this area mainly reflect the lack of outcrop and define soil types and drainage patterns. Opportunities exist for a number of deposit types of economic potential: petroleum near a Bouguer gravity low at Booligal; biogenic Gas and Coal in two grabens extending north from Hay; orogenic Gold associated with an extension of the Bendigo Terrane from Victoria into the Murray Basin; porphyry gold associated with previously unmapped granites; and diamonds associated with the clusters of intrusive pipes in the central west of the survey area.
