A geological report detailing the Permian stratigraphy of the Carnarvon Basin in Western Australia. The report is Part 2 of a three-part series published by the Australian Ocean Data Network, with a last update recorded for 2026-06-27. It describes an epicontinental basin containing sediments from Proterozoic to Tertiary periods, with a maximum known Permian thickness of 15,200 feet.
Use Cases
- Study Permian marine and glacial sediment sequences based on the detailed stratigraphic descriptions.
- Analyze basin structure and depositional history based on the report's discussion of down-warping and lack of tangential stress.
- Correlate geological units across the Carnarvon Basin based on the provided maximum thicknesses for different periods.
- Research regional palaeogeography and economic geology potential referenced as topics covered in the full report series.
Strengths
- Provides detailed maximum sediment thicknesses for multiple geological periods, including a 15,200-foot Permian sequence.
- Part of a structured three-part report series with continued figure numbering, suggesting methodological consistency.
- Covers a defined geographic area extending approximately 130 miles inland from the coast of Western Australia.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- The primary data format is a report (HTML/PDF), not a structured data table, which may limit direct machine analysis.
