Geology and Mineral Deposits of the Granites-Tanami and Tennant Creek Inliers

Northern Australia's Palaeoproterozoic Tennant Creek and Granites-Tanami Inliers share a stratigraphic and tectonic history. Both feature sequences of flysch sediments and volcanics deposited in an intracratonic transtensional basin, deformed during the Barramundi Orogeny, and host regionally significant gold deposits. The dataset describes the geological evolution, structural controls on mineralization, and the uncertain origin of gold-bearing fluids in these terrains.

Use Cases

• Comparative tectonic analysis of the Barramundi Orogeny based on described stratigraphic sequences.
• Identifying regional stratigraphic controls for gold exploration using the Mount Charles beds and Warramunga Formation ironstones.
• Studying the genesis of polymetallic (W, Au, Cu, Bi, U, Ag/Pb) mineralization in the Davenport province.
• Modeling basin evolution from early rift sequences to later fluvial-shallow marine sedimentation.

Strengths

• Cross-platform presence on data.gov.au indicates official curation and importance.
• Provides a detailed, comparative geological synthesis of two major Australian mineral provinces.

Limitations

• Core data attributes (row count, file size, column names) are not provided on any platform.
• The listed update date (2026-04-30) is in the future, casting doubt on metadata accuracy.
• License and author information is missing, limiting clarity on reuse permissions.
