The Australian Geological Survey Organisation (formerly the Bureau of Mineral Resources, Geology and Geophysics) flew an airborne geophysical survey of 63 600 line km over the Dubbo 1:250 000 Map Sheet area from March to May, 1991. This survey, which formed part of the National Geoscience Mapping Accord, was flown along eastwest flight lines 400m apart at an altitude of 100m above ground level. A large portion of the western one-half of the survey area was infilled with additional lines to reduce the line separation to 200m. The NSW Department of Mineral Resources funded the additional flying. Total magnetic intensity and gamma-ray spectrometric data were collected during the survey. These data have been processed and are available for purchase, in both digital (position located data and grids) and map form, from the Australian Geological Survey Organisation.
