Geological Evolution Maps of the Southern Taroom Trough and Surat Basin, Australia

The southern Taroom Trough and overlying Surat Basin in Australia are documented through isopach, structure contour, and palaeo-geological maps. The dataset, published by the Australian Ocean Data Network, describes 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 and Cretaceous sediments.

Use Cases

• Modeling basin subsidence and compaction history based on described sedimentary thickness and structural features.
• Assessing petroleum prospectivity based on described source rocks and reservoir sandstones like the Hutton Sandstone.
• Reconstructing palaeo-geography and tectonic evolution based on isopach and structure contour maps.
• Analyzing sediment distribution patterns from described Permian to Cretaceous depositional sequences.

Strengths

• Covers a large, defined geographic area of 50,000 km² for the Taroom Trough and 300,000 km² for the Surat Basin.
• Provides specific geological metrics, including maximum sedimentary thicknesses of 10,000 m and 2500 m.
• Includes detailed stratigraphic and tectonic history with named formations and structural features.

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/temporal bias inherent to data_gov_au.
