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

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, describes sedimentary sequences from the Permian to Cretaceous periods, including petroleum-producing Lower Jurassic sandstones. It was last updated on 2026-04-20.

Use Cases

• Model subsurface structure and sediment thickness based on isopach and structure contour maps.
• Analyze petroleum migration and trapping mechanisms based on described Permian and Jurassic source rocks.
• Study tectonic evolution and basin subsidence history based on described fault movements and sediment compaction.
• Identify prospective areas for hydrocarbon exploration based on the discussion of the Lower Jurassic Hutton Sandstone.

Strengths

• Covers a large spatial area, detailing a 50,000 km² trough and a 300,000 km² basin.
• Provides specific geological measurements, including sediment thicknesses up to 10,000 m in the trough and 2500 m in the basin.
• Includes detailed temporal context for 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.
• Data is presented in HTML format, which may not be immediately machine-readable for analysis.
