Castlemaine, Woodend, Nth Bacchus Marsh, Vic, 1997 VIMP Survey (GSV3071) (P663), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Castlemaine, Woodend, Nth Bacchus Marsh, Vic, 1997 VIMP Survey (GSV3071) (P663), radiometric line data, AWAGS levelled were acquired in 1996 by the VIC Government, and consisted of 38794 line-kilometres of data at 200m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.
