Canning Basin Geological Evolution and Stratigraphic Intervals

Australian Ocean Data Network provides a geological description of the Canning Basin in Western Australia, covering an area of approximately 430,000 km² onshore and 165,000 km² offshore. The dataset details a sedimentary rock sequence about 10,000 meters thick, divided into 11 basin-wide stratigraphic intervals from the Ordovician to the Eocene. This record was last updated in April 2026.

Use Cases

• Analyze the 11 stratigraphic intervals to model depositional environments and sea-level changes over time.
• Map major structural features like the Fitzroy Graben and sub-basins for tectonic history reconstruction.
• Correlate sedimentary units containing turbidites, evaporites, and glacial debris to specific geological periods.
• Study the relationship between earth movements, such as the Alice Springs Orogeny, and recorded unconformities.

Strengths

• Describes a substantial geological area covering approximately 595,000 km².
• Documents a thick sedimentary sequence of about 10,000 meters.
• Provides a detailed chronological framework with 11 defined stratigraphic intervals.

Limitations

• Data is presented as descriptive text in PDF/HTML, not as structured, queryable data.
• No quantitative measurements, sample data, or columnar information are provided.
• The temporal coverage is broad but described qualitatively without precise date ranges for all intervals.
