Geology of the Proterozoic Davenport Province, Central Australia

Geoscience Australia Data provides a geological description of the Proterozoic Davenport province, situated between the Tennant Creek and Arunta Inlier regions. The data describes sedimentary, volcanic, and intrusive rock sequences, including the 1870 Ma-old Warramunga Group and the at least 10 km thick Hatches Creek Group. It includes details on rock types, stratigraphy, geochemistry, deformation history, and recorded mineral production of about 4500 t tungsten concentrates and 15 kg gold.

Use Cases

• Modeling ancient sedimentary environments based on described fluvial and shallow marine facies.
• Correlating regional stratigraphy using described subgroups, formations, and correlations to the Tomkinson Creek beds and Arunta Inlier.
• Analyzing geochemical signatures for mineral exploration based on described differences in Ti, P, Th, U, Zr, Nb, Y, Ca, Al, Sr, and V contents in felsic volcanics.
• Interpreting subsurface geology using described aeromagnetic and gravity geophysical data correlations.
• Studying the tectonic history of an extensional ensialic setting based on the described volcanic, sedimentary, and deformation sequence.

Strengths

• Includes specific geochronological dates, such as 1870 Ma for the Warramunga Group and 1660 Ma for subsequent granite intrusions.
• Provides detailed stratigraphic thickness and composition, noting the Hatches Creek Group is at least 10 km thick and comprises three subgroups, twenty formations, and two named members.
• Contains quantified historical mineral production data, specifically about 4500 tonnes of tungsten concentrates and 15 kg of gold.
• Integrates multiple data types, including described rock chemistry, geophysical anomalies, and field observations.

Limitations

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