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

Isopach, structure contour, and palaeo-geological maps illustrate the geological development of the southern Taroom Trough and the lower part of the Surat Basin sequence. The dataset covers a 50,000 km² trough and a 300,000 km² basin, detailing sedimentary fill, tectonic history, and petroleum potential. It was published by Geoscience Australia Data and last updated on 2026-03 25.

Use Cases

• Model basin subsidence and compaction based on isopach and structure contour maps.
• Analyze petroleum migration and trapping mechanisms based on described structural features like the Mimosa Syncline.
• Study tectonic evolution based on the described faulting and movement timelines from the Late Permian to Late Triassic.
• Correlate stratigraphic sequences based on described sedimentary units like Permian coal measures and Jurassic stream sediments.

Strengths

• Covers a large, defined geographical area of 50,000 km² for the Taroom Trough and 300,000 km² for the Surat Basin.
• Includes specific geological measurements, such as sedimentary fill thickness ranging from less than 400 m to 10,000 m.
• Provides a detailed tectonic timeline, specifying fault movement periods from the Late Permian to Late Triassic.

Limitations

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