Geoscience Australia Data provides geological data for the Proterozoic River Supersequence, a stratigraphic unit in the Isa Superbasin. The supersequence comprises eight 3rd-order sequences and attains a maximum thickness of 3300 meters on the central Lawn Hill Platform. It documents a dynamic period of basin partitioning, syndepositional faulting, and includes at least three stratigraphic levels associated with Zn-Pb-Ag mineralization.
Use Cases
- Modeling basin architecture and fault-controlled deposition based on described seismic and outcrop-scale thickness changes.
- Analyzing facies distributions and paleoenvironments based on described siliciclastic, carbonate, and turbidite deposits.
- Investigating controls on base-metal mineralization based on the described stratigraphic levels associated with Zn-Pb-Ag.
- Reconstructing accommodation cycles and sequence stratigraphy based on the described 2nd- and 3rd-order sequences.
Strengths
- Maximum thickness of the supersequence is documented as 3300 meters.
- The description details eight 3rd-order sequences within the 2nd-order cycle.
- Spatial coverage is specified across the central and northern Lawn Hill Platform and McArthur Basin.
- Facies and depositional systems are described, including fluvial, shoreface, and turbidite environments.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last metadata update was 2026-04-20 03:01:49.307845.
