The Australian Ocean Data Network provides isopach, structure contour, and palaeo-geological maps illustrating the geological development of the southern Taroom Trough and the overlying Surat Basin. The dataset covers a 50,000 km² trough and a 300,000 km² basin, detailing sedimentary fill up to 10,000 meters thick and discussing petroleum potential. It was last updated on 2026-04-16.
Use Cases
- Modeling basin subsidence and compaction history based on isopach and structure contour maps.
- Assessing petroleum prospectivity in Lower Jurassic sandstones based on described migration and trapping mechanisms.
- Analyzing tectonic evolution based on the timing of fault movements and syncline formation described.
- Correlating sedimentary facies and thickness changes across the 350,000 km² combined area of the trough and basin.
Strengths
- Covers a large, defined geographical area of 350,000 km² combined for the Taroom Trough and Surat Basin.
- Includes specific geological measurements, such as sedimentary fill thickness ranging from less than 400 m to 10,000 m.
- Provides a detailed chronological narrative of tectonic events from the Permian to the Jurassic.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for quantitative analysis.
- The primary file format is HTML, which may not be readily machine-readable for analysis.
