Geology of the Proterozoic Davenport Province, Central Australia

4500 tonnes of tungsten concentrates and 15 kg of gold were recorded from mineralisation in the Davenport province. The dataset describes the sedimentary, volcanic, and intrusive rocks of this Proterozoic geological province, including stratigraphic groups, formation ages, and geophysical characteristics. It is provided by the Australian Ocean Data Network via data.gov.au and was last updated in May 2026.

Use Cases

• Correlate stratigraphic units based on described rock types and formation ages.
• Identify potential mineral exploration targets based on described tungsten and gold mineralisation.
• Model subsurface geology using described aeromagnetic and gravity geophysical data.
• Study Proterozoic tectonic settings based on the described extensional ensialic environment.

Strengths

• Includes specific production figures: 4500 tonnes of tungsten concentrates and 15 kg of gold.
• Provides detailed geological chronology with specific age ranges, such as 1870 Ma and 1810-1820 Ma.
• Describes geophysical correlation methods, such as using contoured aeromagnetics to trace subsurface units.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
