Permian Stratigraphy of the Carnarvon Basin, Western Australia

Part 2 of a three-part geological report details the Permian stratigraphy of the Carnarvon Basin, an epicontinental basin with a maximum known Permian thickness of 15,200 feet. The report, published by Geoscience Australia, describes marine sediments, including glacial deposits, that rest unconformably on older rocks. It provides detailed thickness breakdowns for Sakmarian, Artinskian, and Kungurian stages.

Use Cases

• Modeling sedimentary basin evolution based on described stratigraphic sequences and thicknesses.
• Studying Permian marine glacial sediments and their depositional environments as detailed in the report.
• Correlating regional geology using the provided thickness data for different geological periods.
• Analyzing large-scale structural history based on the description of depositional structures and epeirogenic movements.

Strengths

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

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 in report format (PDF/HTML); structured tabular data is not guaranteed.
