Proterozoic Davenport Province Geology And Mineralization

1870 to 1660 million-year-old geological data for the Davenport province in central Australia, detailing sedimentary, volcanic, and intrusive rock sequences. The Australian Ocean Data Network compiled this report, which includes records of mineral production such as 4500 tonnes of tungsten concentrates and 15 kg of gold. The dataset was last updated in April 2026.

Use Cases

• Correlate rock formations like the Warramunga and Hatches Creek Groups using geochemical features such as Ti, P, Th, U, Zr, Nb, Y, Ca, Al, Sr, and V content.
• Map subsurface extensions of Hatches Creek Group units using contoured aeromagnetic data described in the report.
• Analyze the distribution of mineralisation, particularly quartz veins with wolframite and scheelite, within the lower part of the Hatches Creek Group.
• Study the tectonic setting by examining the described sedimentary environments (fluvial, shallow marine) and bimodal volcanic sequences.

Strengths

• Provides detailed stratigraphic breakdown including three subgroups, twenty formations, and two named members within the Hatches Creek Group.
• Includes specific production figures for mineral resources, such as 4500 t tungsten concentrates and 15 kg gold.
• Covers a substantial geological time range from approximately 1870 to 1660 million years ago.

Limitations

• Sample data and specific row/column counts are unavailable, limiting quantitative analysis.
• Data is presented in PDF and HTML formats, which are not readily machine-readable for direct computational use.
• The geographic scope is restricted to a single province in central Australia.
