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

A geological report from Geoscience Australia describing the stratigraphy, tectonic evolution, and mineral deposits of two Palaeoproterozoic inliers in the Northern Territory. The document details sequences of flysch sediments, volcanics, and granitoid intrusions associated with the Barramundi Orogeny, with a focus on gold mineralization. The dataset was last updated on 2026-05-14 and is available in PDF and HTML formats.

Use Cases

• Analyzing regional stratigraphic controls for gold deposits based on descriptions of the Mount Charles beds and Warramunga Formation ironstones.
• Studying the role of structural controls in local-scale mineralization as described for the inliers.
• Investigating the origin of mineralizing fluids based on discussions of magmatic and metamorphic fluid components.
• Mapping basin and dome structures formed by D2 and D3 deformation episodes described in the report.
• Identifying potential for other metals like W, Cu, Bi, U, Ag/Pb based on descriptions of vein quartz-hosted mineralization in the Davenport province.

Strengths

• Report provides detailed geological descriptions of stratigraphy, tectonic evolution, and mineralization.
• Focus on a specific, economically significant mineral commodity (gold) is clearly stated.
• Document is from an authoritative source, Geoscience Australia Data.
• Last update timestamp is precisely provided: 2026 05 14 08:54:57.869189.

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 two Northern Territory inliers.
