Hydrocarbon and Geothermal Prospectivity of Central Australian Sedimentary Basins

Central Australia, bounded by 22.5°S 134°E and 31.5°S 144°E, contains stacked sedimentary basins beneath the Mesozoic Eromanga Basin. The dataset describes the geological history and preserved depocentres of the Warburton, Cooper, Pedirka, Galilee, Simpson, and Eromanga Basins. It was published by the Australian Ocean Data Network and is scheduled for an update in May 2026.

Use Cases

• Model hydrocarbon prospectivity based on descriptions of organically-mature continental coal measure sequences.
• Analyze basin evolution and tectonism based on the described geological history from the Carboniferous to the Cainozoic.
• Map preserved depocentres for exploration planning based on the spatial separation of the Cooper, Pedirka-Simpson, and Galilee Basins.
• Assess geothermal potential based on the described basin inversion and subsidence events.

Strengths

• Focuses on a specific geographic region bounded by coordinates 22.5°S 134°E and 31.5°S 144°E.
• Describes multiple basin systems (Warburton, Cooper, Pedirka, Galilee, Simpson, Eromanga) with a detailed geological timeline.
• Scheduled for an update on 2026-05-05, indicating planned maintenance.

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 Central Australia.
