Summary(Plain Language Summary, not published)
Airborne gravity gradiometry surveys measure the gravitational field of the Earth. The field was measured by a gravity gradiometer aboard an aircraft flown at 80 m altitude in parallel lines spaced at 500 m across the survey area. The gravitational field reflects density contrasts in the underlying bedrock and provides qualitative and quantitative information used in geological mapping. Understanding the geology will help geologists map the area, assist mineral/hydrocarbon exploration activities, and provide useful information necessary for communities, aboriginal associations, and government to make land use decisions. This survey was flown to improve our knowledge of the area. It will support ongoing geological mapping and resource assessment.
