Geological Evolution of the Southern Taroom Trough and Surat Basin, Australia

The southern Taroom Trough and overlying Surat Basin in Australia are described through isopach, structure contour, and palaeo-geological maps. The Taroom Trough covers 50,000 km2 with up to 10,000 m of sedimentary fill, while the Surat Basin covers 300,000 km2 with up to 2500 m of sediment. The dataset, hosted by the Australian Ocean Data Network, was last updated on 2026-06-05.

Use Cases

• Modeling basin subsidence and compaction history based on described sediment thickness and tectonic movement timelines.
• Assessing petroleum prospectivity in the Lower Jurassic Hutton Sandstone based on the discussion of migration and trapping.
• Mapping regional structural features like the Mimosa and Dirranbandi Synclines described in the geological evolution.
• Correlating Permian and Jurassic sediment sequences for stratigraphic analysis as detailed in the description.

Strengths

• Covers a large geographic area of 350,000 km2 combined for the two basins.
• Provides specific sediment thickness ranges, from less than 400 m to 10,000 m in the Taroom Trough.
• Includes a detailed chronological narrative of tectonic events from the Permian to the Late Jurassic.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified despite the 2026 update date, as the underlying geological study may be older.
