Beetaloo Sub-basin boundary

\n## **Abstract** \n The boundary defining the spatial extents of the Beetaloo Sub-basin represents the top Kyalla Formation at a depth of approximately 400 m below topographic surface. The depth to top Kyalla Formation is calculated from the interpretation of 96 seismic lines constrained by 26 wells. The spatial extent of the boundary is further constrained by potential field geophysics.\n\n\n## **Attribution** \n Northern Territory Geological Survey (NTGS) Department of Primary Industries and Resources\n\n\n## **History** \nThe Mesoproterozoic Beetaloo Sub-basin is a fully concealed sub-basin located approximately 300 km southeast of Katherine. It comprises thick successions of the Roper Group within the McArthur Basin.
