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 the Australian Ocean Data Network, includes marine glacial sediments and divides the Permian into Sakmarian, Artinskian, and Kungurian stages. It describes the basin's structure, which is characterized by depositional features and large-scale down-warping rather than tangential stress.

Use Cases

• Modeling depositional environments based on described marine glacial sediments and unconformities.
• Correlating stratigraphic sequences using the detailed thickness data for Sakmarian, Artinskian, and Kungurian stages.
• Studying basin evolution and paleogeography based on the report's analysis of transgression and regression events.

Strengths

• Report provides specific maximum thickness measurements for multiple geological periods, including a 15,200-foot Permian section.
• Describes the basin's structural history in detail, noting the absence of tangential stress and prevalence of depositional structures.
• Part of a structured three-part series with continuous figure numbering, providing broader geological context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified as the last updated metadata is for a future date (2026-06-16).
