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

A biostratigraphy chart from Geoscience Australia defines fossil-based biozones for correlating sedimentary rock layers in the Roebuck and Offshore Canning Basin. The chart uses index fossils like foraminifera and dinoflagellate cysts to establish relative geological ages. It was last updated on 2026-04-20.

Use Cases

• Correlating sedimentary rock successions based on fossil index species mentioned in the description.
• Calibrating relative geological timescales using biozones defined by first and last fossil appearances.
• Supporting basin analysis and resource exploration in the Offshore Canning Basin region.

Strengths

• Chart is produced by Geoscience Australia, a national geological authority.
• Description details the scientific methodology of biostratigraphy and biozone definition.
• Last update timestamp (2026-04-20) is provided.

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 basin focus.
