Geology of the Proterozoic Davenport Province in Central Australia

1870 Ma-old Warramunga Group turbiditic sediments form the oldest rocks in the Davenport province, overlain by the at least 10 km thick Hatches Creek Group. The dataset, hosted by the Australian Ocean Data Network, describes sedimentary, volcanic, and intrusive rock sequences, their geochemistry, and associated mineralisation. Total recorded production from the region amounts to about 4500 t tungsten concentrates and 15 kg gold.

Use Cases

• Modeling extensional ensialic tectonic settings based on described bimodal volcanic sequences and sedimentation patterns.
• Identifying potential mineral exploration targets based on described quartz veins with wolframite, scheelite, and auriferous veins.
• Correlating geological units with the Tomkinson Creek beds and Arunta Inlier based on stratigraphic descriptions.
• Analyzing geophysical signatures using described gravity lows and contoured aeromagnetic data for subsurface tracing.

Strengths

• Description provides specific geological timeframes, such as the 1870 Ma-old Warramunga Group and 1810-1820 Ma-old felsic volcanics.
• Includes quantified mineral production figures: about 4500 t tungsten concentrates and 15 kg gold.
• Details stratigraphic thickness and composition, noting the Hatches Creek Group is at least 10 km thick with three subgroups and twenty formations.

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 solely on central Australia.
