Australian Ocean Data Network provides a biostratigraphy chart for the Roebuck and Offshore Canning Basin. The chart uses fossil taxa to establish relative ages and correlate sedimentary rock successions. It was last updated on 2026-05-05.
Use Cases
- Establish relative ages of rock layers based on fossil index species.
- Correlate sedimentary rock successions within and between basins using biozones.
- Calibrate fossil-based zones to the absolute geological timescale using radio-isotopic tie points.
- Study the distribution and abundance of fossil groups like foraminifera or dinoflagellate cysts.
Strengths
- Chart is based on established biostratigraphic principles using key fossil index species.
- The description details the methodology for defining biozones using first appearances and last appearances.
- The chart is provided by the Australian Ocean Data Network, a recognized data aggregator.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The data format is PDF/HTML, which may require parsing for structured analysis.
