Roebuck and Offshore Canning Basin Biozonation Chart No.14

Biozonation Chart No.14 provides a fossil-based stratigraphic framework for the Roebuck and Offshore Canning Basin. The chart, published by the Australian Ocean Data Network, uses index fossils like foraminifera and dinoflagellate cysts to correlate rock layers and establish relative geological ages. It is available in PDF and HTML formats and was last updated in April 2026.

Use Cases

• Correlating sedimentary rock successions based on fossil index species mentioned in the description.
• Calibrating relative geological ages to the absolute timescale using described biozone tie points.
• Studying basin evolution and depositional history using the described biostratigraphic framework.

Strengths

• Chart is specifically focused on the Roebuck and Offshore Canning Basin.
• Description details the scientific principles of biostratigraphy and biozone definition.
• Last updated date is explicitly provided: 2026-04-10 22:23:52.927106.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on an Australian basin.
