Permian Stratigraphy Report for the Carnarvon Basin, Western Australia

Western Australia's Carnarvon Basin is an epicontinental basin containing Proterozoic, Palaeozoic, Mesozoic, and Tertiary sediments. This report, Part 2 of a three-part series from the Australian Ocean Data Network, details the Permian stratigraphy, including marine glacial sediments with a maximum known thickness of 15,200 feet. The report was last updated in April 2026.

Use Cases

• Analyze Permian marine sediment deposition patterns based on described stratigraphic sequences.
• Study geological structures and basin evolution based on the description of depositional structures and down-warping.
• Model historical sea-level changes based on the described relationship to marine transgressions and regressions.
• Correlate subsurface rock units based on the described thicknesses for Sakmarian, Artinskian, and Kungurian stages.

Strengths

• Provides detailed maximum thickness measurements for multiple geological periods, including a 15,200-foot Permian section.
• Part of a structured three-part report series with continued figure numbering for cross-referencing.
• Describes the basin's geographic extent, from Onslow to near Geraldton and about 130 miles inland.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented as a PDF/HTML report, not as structured tabular data for direct analysis.
