Permian Stratigraphy Report for the Carnarvon Basin

Part 2 of a geological report details the Permian stratigraphy of the Carnarvon Basin in Western Australia. The report, published by the Australian Ocean Data Network, provides thickness data for geological periods, including Permian sediments up to 15,200 feet thick. It describes the basin's structure and sedimentary history from the Proterozoic to the Tertiary.

Use Cases

• Analyzing Permian sediment thicknesses (e.g., Sakmarian 7200 feet) for basin modeling.
• Studying the spatial distribution of geological units like marine Devonian sandstone or Tertiary limestone.
• Investigating depositional structures and the absence of tangential stress as described in the report.

Strengths

• Report provides specific maximum thickness measurements for multiple geological periods (e.g., Permian 15,200 feet).
• Covers a defined geographical area extending about 130 miles inland from the coast.

Limitations

• Data is presented as a textual report (PDF/HTML), not a structured, machine-readable dataset.
• Sample size and row counts for underlying data points are unknown.
• Information may be temporally stale relative to modern geological surveys.
