Proterozoic River Supersequence Stratigraphy and Facies on the Lawn Hill Platform

The River Supersequence dataset describes a 15-million-year stratigraphic unit within the Isa Superbasin of northern Australia. It comprises eight sequences with a maximum thickness of 3300 meters, featuring siliciclastic and carbonate facies, lowstand deposits, and syndepositional faulting. This geological data was published by the Australian Ocean Data Network and is associated with research on Zn-Pb-Ag mineralisation.

Use Cases

• Modeling basin partitioning and accommodation cycles based on described sequence stratigraphy.
• Analyzing facies distribution and depositional environments like shoreface and turbidite systems.
• Correlating stratigraphy with base-metal mineralisation across the three described levels.
• Studying synsedimentary fault movement and its impact on sediment thickness and facies changes.

Strengths

• Maximum thickness of the supersequence is documented as 3300 meters.
• Describes eight 3rd-order sequences within a defined 15-million-year cycle.
• 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 is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific study area on the Lawn Hill Platform.
