Geological Maps of the Southern Taroom Trough and Surat Basin Evolution

Isopach, structure contour, and palaeo-geological maps illustrate the geological development of a 50,000 km² trough and a 300,000 km² overlying basin. The dataset, from Geoscience Australia, includes details on sedimentary fill thickness, tectonic history, and petroleum potential. It was last updated on 2026-05-14.

Use Cases

• Model basin subsidence and compaction history based on described isopach and structure contour maps.
• Assess petroleum prospectivity in Lower Jurassic sandstones based on described migration and trapping discussions.
• Reconstruct palaeo-environments and sediment deposition based on described sequences of marine, coal, and stream sediments.
• Analyze tectonic fault timing and basin structural features like the Mimosa and Dirranbandi synclines.

Strengths

• Covers a large, defined geographic area of 350,000 km² combined for the two basins.
• Describes specific geological features and sequences, including thickness ranges from less than 400 m to 10,000 m.
• Includes discussion of petroleum sources and potential prospective areas like the Bollon area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in HTML format, which may require extraction for computational analysis.
