TEMPEST™ Airborne EM Data for Induced Polarization Modelling in the Musgrave Province

Geoscience Australia Data provides field survey data from the TEMPEST™ fixed-wing airborne electromagnetic (AEM) system, used to model induced polarization (IP) effects. The dataset covers three exploration scales, including a regional-scale inversion of the Musgrave Province in South Australia and deposit-scale analysis of the Nemo-Babel mineralization. The data was last updated on 2026-06 17.

Use Cases

• Comparing fixed-wing and helicopter-borne AEM system performance based on overlapping survey line data mentioned in the description
• Inverting regional-scale airborne electromagnetic surveys for induced polarization effects based on the Musgrave Province case study
• Ground-truthing modelled chargeability anomalies against known mineralized zones based on the Nemo-Babel analysis
• Assessing the impact of IP modelling on inversion misfit and resistivity distributions as described in the regional study

Strengths

• Data is associated with a peer-reviewed study published in Geophysical Journal International, Volume 245, Issue 1, April 2026
• Analysis spans three distinct exploration scales: deposit, survey-line, and regional scale
• Includes comparative modelling with a helicopter-borne system (SkyTEM312FAST) along overlapping lines
• Regional-scale inversion covers the entire Musgrave Province in South Australia

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 data_gov_au, focusing on Australian regions
