Geology of the Proterozoic Davenport Province, Central Australia

Geological data for the Davenport province in central Australia, situated between the Tennant Creek and Arunta Inlier regions. The description details sedimentary, volcanic, and intrusive rocks, including the 1870 Ma Warramunga Group and the at least 10 km thick Hatches Creek Group. The dataset is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Map subsurface geology based on described contoured aeromagnetic data.
• Model mineral prospectivity for tungsten and gold based on described stratigraphic controls.
• Analyze geochemical signatures of felsic and mafic volcanics based on described elemental variations.
• Reconstruct Proterozoic tectonic environments based on described extensional ensialic setting.

Strengths

• Description includes specific geological timeframes, such as 1870 Ma for the Warramunga Group.
• Contains quantified historical mineral production figures, including about 4500 t tungsten concentrates and 15 kg gold.
• Integrates multiple data types, including geological mapping, geophysical (gravity, aeromagnetic), and geochemical information.

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 a specific Australian province.
