Abstract

Deep weathering and extensive tertiary and quaternary cover over some 350 000 sq. km of Archaean greenstone and granitic rocks of the Eastern Goldfields province of Western Australia have rendered much of the area inaccessible to direct methods of exploration. This paper shows how combined airborne magnetic and radiometric surveys with high quality resolution flown by Aerodata Holdings Ltd comprising 140 000 line km in the Wiluna Norseman sub-province (Fig. 1) have successfully penetrated the extensive cover and assisted in the geological interpretation of some 25 000 sq. km of the sub-province.
