Roebuck and Offshore Canning Basin Biozonation and Stratigraphy Chart No.14

Roebuck and Offshore Canning Basin Biozonation and Stratigraphy Chart No.14 is a biostratigraphic reference chart from the Australian Ocean Data Network. It uses fossil index species to define biozones for correlating sedimentary rock successions. The chart was last updated on 2026-06-04.

Use Cases

• Correlating sedimentary rock layers based on fossil index species mentioned in the description.
• Calibrating biozones to the absolute geological timescale using described radio-isotopic tie points.
• Establishing relative ages of rock strata using described fossil groups like foraminifera or dinoflagellate cysts.

Strengths

• Chart is specifically focused on the Roebuck and Offshore Canning Basin regions.
• Description details the scientific principles of biostratigraphy and biozone definition.
• Last update timestamp is precisely recorded as 2026-06-04 06:40:16.888636.

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 the specific Australian basins covered.
