The Australian Ocean Data Network provides a geological bulletin describing the southern McArthur Basin in the Northern Territory. The description details a mid-Proterozoic sedimentary sequence divided into four stratigraphic groups with reported thicknesses up to 12 kilometers. The data was last updated on June 5, 2026.
Use Cases
- Modeling basin evolution based on described stratigraphic groups and unconformities.
- Analyzing depositional environments based on described rock types like evaporitic dolostones and quartz sandstones.
- Studying structural geology based on the described Batten Fault Zone and wrench-faulting.
- Correlating regional geology using the provided U-Pb age of 1690±25 Ma.
Strengths
- Provides specific geological thicknesses, such as the Tawallah Group at about 4500 meters.
- Includes a precise radiometric date (U-Pb age of 1690±25 Ma) for stratigraphic correlation.
- Describes detailed stratigraphic divisions and structural features like the Batten Trough.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
