Proterozoic River Supersequence Geology of the Lawn Hill Platform, Australia

The River Supersequence dataset describes a 15-million-year Proterozoic stratigraphic unit in the Isa Superbasin, northern Australia. It comprises eight 3rd-order sequences with a maximum thickness of 3300 meters, documented through outcrop, drillhole, and seismic analysis. The data was published by the Australian Ocean Data Network and is associated with a 2000 scientific citation.

Use Cases

• Modeling sedimentary basin evolution based on described sequence stratigraphy and accommodation cycles.
• Analyzing syndepositional faulting and basin partitioning based on documented fault offsets and thickness changes.
• Studying paleoenvironmental transitions based on described facies changes from siliciclastic shorelines to turbiditic sub-basins.
• Investigating base-metal mineralisation patterns based on the three identified stratigraphic levels associated with Zn-Pb-Ag.

Strengths

• Describes a specific 15-million-year stratigraphic cycle with a documented maximum thickness of 3300 meters.
• Integrates multiple data sources including outcrop, drillhole, and seismic analysis.
• Identifies at least three stratigraphic levels associated with base-metal mineralisation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific Lawn Hill Platform study area.
