Geological Survey of the Proterozoic Davenport Province

Geological data describes the Proterozoic Davenport province in central Australia, detailing its sedimentary, volcanic, and intrusive rock composition. The report covers the Warramunga and Hatches Creek Groups, including formation ages, thickness, mineralogy, and recorded mineral production like 4500 tonnes of tungsten concentrates. This information was published by the Australian Ocean Data Network.

Use Cases

• Correlate rock formations like the Hatches Creek Group with other regional sequences using described lithology and geochemical signatures.
• Analyze the distribution of mineralisation, such as tungsten and gold, within specific stratigraphic levels of the Hatches Creek Group.
• Model the extensional ensialic tectonic setting using data on bimodal volcanism, sedimentation rates, and faulting.
• Interpret geophysical anomalies by linking gravity lows and aeromagnetic contours to subsurface granite intrusions and volcanic units.
• Study paleoenvironments by examining described fluvial and shallow marine sedimentary facies within the group's subgroups and formations.

Strengths

• Detailed stratigraphic breakdown of the Hatches Creek Group into three subgroups, twenty formations, and two named members.
• Includes specific geochemical comparisons between volcanic groups, noting differences in Ti, P, Th, U, Zr, Nb, Y, Ca, Al, Sr, and V content.
• Provides quantified historical mineral production figures, including about 4500 tonnes of tungsten concentrates and 15 kg of gold.

Limitations

• No structured data columns or sample records are provided, only descriptive text in report format.
• The spatial data is described narratively; precise geographic coordinates or vector/raster files are not specified.
• Temporal coverage is focused on the Proterozoic era with specific formation dates, but lacks modern time-series data.
