Southern Taroom Trough and Surat Basin Geological Maps

Isopach, structure contour, and palaeo-geological maps illustrate the geological development of the southern Taroom Trough, a 50,000 km² subsurface extension of the Bowen Basin, and the overlying 300,000 km² Surat Basin. The dataset likely contains maps detailing sedimentary thickness, structural features, and stratigraphic sequences from the Permian to Cretaceous periods. It is hosted by the Australian Ocean Data Network on data.gov.au.

Use Cases

• Analyze basin subsidence and compaction history based on isopach maps showing sedimentary thickness from less than 400 m to 10,000 m.
• Model petroleum migration and trapping based on descriptions of structural features like the Mimosa and Dirranbandi Synclines.
• Study stratigraphic sequences and depositional environments based on described Permian marine sediments, Upper Permian coal measures, and Jurassic stream sediments.
• Assess hydrocarbon prospectivity in specific areas like the Bollon region based on discussions of Lower Jurassic sandstone potential.

Strengths

• Includes detailed geological maps (isopach, structure contour, palaeo-geological) for a 50,000 km² and a 300,000 km² basin.
• Description provides specific geological facts, such as maximum sedimentary thickness increasing northward from less than 400 m to 10,000 m.
• Covers a long temporal sequence from the Lower Permian to the Lower Cretaceous, detailing multiple sedimentary phases.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on a specific Australian region.
