Permian Stratigraphy of the Carnarvon Basin, Western Australia

Western Australia's Carnarvon Basin, an epicontinental basin extending from Onslow to near Geraldton, is documented in this geological report. The report details Permian marine sediments, including glacial deposits, with a maximum known thickness of 15,200 feet, subdivided into Sakmarian, Artinskian, and Kungurian stages. It is part of a three-part series published by Geoscience Australia, with the last metadata update recorded in 2026.

Use Cases

• Modeling depositional environments based on described marine glacial sediments and unconformities.
• Correlating stratigraphic sequences using the detailed thickness data for Permian, Jurassic, Cretaceous, and Tertiary layers.
• Analyzing basin evolution from the described history of intermittent marine transgression and regression.
• Studying structural geology from the report's focus on depositional structures and large-scale down-warping without tangential stress.

Strengths

• Provides detailed maximum thickness measurements for multiple geological periods, including a 15,200-foot Permian sequence.
• Offers a regional geological context, describing the basin's geographic extent of about 130 miles inland from the coast.
• Part of a structured three-part report series with continued figure numbering for cohesive reference.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF/HTML report formats, not a structured data table.
