Geoscience Australia provides a biozonation and stratigraphy chart for the Roebuck and Offshore Canning Basin. The chart uses fossil index species to establish relative rock ages and correlate sedimentary successions. It was last updated on March 25, 2026.
Use Cases
- Correlating sedimentary rock successions based on fossil index species mentioned in the description
- Calibrating biozones to the absolute geological timescale using described tie points
- Establishing relative rock ages using described fossil groups like foraminifera or dinoflagellate cysts
Strengths
- Focuses on a specific geological region: the Roebuck and Offshore Canning Basin.
- Describes the use of key fossil index species for establishing relative ages.
- Last update timestamp is precisely recorded: 2026-03-25 16:19:54.804457.
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.
