The Australian Geological Survey Organisation (AGSO) flew an airborne geophysical survey of 39,698 line kilometres over all but the southwestern 1:100 000 map Sheet area of the Throssell 1:250 000 map Sheet area in the Eastern Goldfields of Western Australia. The survey was flown in two separate blocks known as the eastern block and western block. The eastern block covers the eastern two thirds of the Throssell 1:250 000 Sheet (Blaxland, Buldya, Yamarna and Lake Throssell 1:100 000 Sheets) area and the western block covers the northern half of the western third of the sheet (Strawbridge 1:100 000 Sheet). The survey area covers part of the northeast margin of the Yilgarn Craton. Intermittent Archaean outcrop is restricted to the western half of the survey area. The cover includes Proterozoic Earaheedy Basin sediments in the north and Palaeozoic Officer Basin sediments in the east. The eastern block was flown along north-south flight lines and the western block was flown along east-west flight lines. Both blocks were flown at 400 m line spacing at a nominal altitude of 60 m above ground level. AGSO flew the survey in May and June 1998. The total magnetic intensity, gamma-ray spectrometric and digital elevation model data which were collected during the survey, have been processed and merged with a separately acquired neighbouring dataset covering the south-western 1:100 000 map Sheet area (Jutson 1:100 000 Sheet). The entire dataset is available for purchase, in both digital (point located data and gridded) and map form, from AGSO. Additionally an interpretation of the data is available from AGSO.
