Geological data describes the Proterozoic River Supersequence, an approximately 15-million-year stratigraphic unit in the Isa Superbasin. The dataset includes information on eight 3rd-order sequences, facies distributions, and thickness variations up to 3300 meters, documented from outcrops, drillholes, and seismic imaging. It was published by Geoscience Australia and is associated with research on basin partitioning and Zn-Pb-Ag mineralisation.
Use Cases
- Modeling syndepositional fault movement and basin partitioning based on described fault offsets and thickness changes.
- Analyzing facies distributions and depositional environments from described siliciclastic, carbonate, and turbidite intervals.
- Investigating the relationship between stratigraphic architecture and base-metal mineralisation at three described levels within the supersequence.
Strengths
- Describes a stratigraphic unit with a defined duration of approximately 15 million years.
- Includes specific maximum thickness measurements (3300 m) and documents facies changes across fault blocks.
- Links geological architecture to mineralisation, noting at least three stratigraphic levels with base-metal potential.
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.
