Northern Territory Geological Survey: New gravity grid of the Northern Territory

摘要

The Northern Territory Geological Survey (NTGS) has released a new Territory-wide gravity grid (Figure 1). The new grid incorporates the recently released East Tennant and South West McArthur-Barkly gravity surveys, both funded under Geoscience Australia's Exploring for the Future programme. NTGS also contributed funding to extend the South West McArthur-Barkly gravity survey under the Northern Territory Government's Resourcing the Territory 2018-22 initiative. These surveys infilled existing 4 kmspaced data to 2 km. Figure 2 illustrates the finer scale of features visible in the new grid over the East Tennant area.
