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 dataset, from Geoscience Australia, details a 50,000 km² trough with up to 10,000 m of sedimentary fill and a 300,000 km² basin with up to 2500 m of Jurassic-Cretaceous sediments. It was last updated on 2026-04-30.

Use Cases

• Modeling basin subsidence and compaction history based on described sediment thickness and tectonic movement timelines.
• Identifying potential petroleum traps based on structural features like the Mimosa and Dirranbandi Synclines.
• Correlating stratigraphic units and depositional environments from the described Permian to Cretaceous sediment sequences.
• Assessing hydrocarbon prospectivity in specific formations, such as the Lower Jurassic Hutton Sandstone in the Bollon area.

Strengths

• Covers a large geographic area, detailing a 50,000 km² trough and a 300,000 km² basin.
• Provides specific quantitative data, including sediment thicknesses up to 10,000 m and 2500 m.
• Includes a detailed geological timeline from the Permian to the Cretaceous with tectonic events.

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 conversion for spatial analysis.
