The Kenn Plateau Off Northeast Australia: an Important Continental Fragment in the Southwe

140,000 km² of submarine plateau east of Queensland, representing a thinned continental fragment that rotated away from Australia. Geoscience Australia data describes its Cretaceous to present geological history, including fault blocks, sedimentary basins, volcanic chains, and 2000 m of subsidence. The dataset, last updated in April 2026, likely contains interpreted geophysical and geological information.

Use Cases

• Modeling plate tectonic reconstruction based on described rotation and fault block geometry
• Analyzing sedimentary basin development using described sequences of siliciclastic and carbonate sediments
• Studying volcanic hotspot chains and seamount formation based on the Tasmantid and Lord Howe chains
• Investigating subsidence and reef evolution patterns from the described 2000 m of plateau subsidence

Strengths

• Describes a specific, large (140,000 km²) geological feature with a detailed evolutionary timeline
• Includes multiple concrete geological processes: faulting, sedimentation, volcanism, subsidence, and unconformities
• Sourced from Geoscience Australia, a national geological survey organization

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data format is HTML, which may not be structured for direct analysis
