Chronostratigraphic AEM Interpretation for the Halls Creek-Birrindudu-Tanami Region

Interpreted airborne electromagnetic (AEM) data from the 2019–20 AusAEM survey covering over 200,000 km² in the Birrindudu Deep Dive region. The dataset comprises approximately 11,250 km of conductivity sections and is produced by Geoscience Australia as part of the Resourcing Australia’s Prosperity initiative. These interpretations provide multidisciplinary data for geological studies, including cover thickness modelling and resource prospectivity mapping.

Use Cases

• Resource prospectivity mapping based on interpreted subsurface stratigraphic unit boundaries.
• Groundwater potential assessment based on mapped palaeovalley features.
• Tectonic and geological evolution research based on mapped faulting and neotectonic features.
• Cover thickness modelling for geological studies based on the conductivity sections.
• Environmental monitoring and land-use planning based on multidisciplinary geological insights.

Strengths

• Covers an area over 200,000 km², almost the size of the state of Victoria.
• Comprises approximately 11,250 km of interpreted conductivity sections.
• Contributes to a national-scale chronostratigraphic interpretation covering over 115,000 km of AEM flight lines across approximately 27% of the Australian continent.
• Supports a multidisciplinary approach with features mapped for mineralisation, groundwater, and tectonics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey region.
