Canning Basin Borehole Biostratigraphy and Stratigraphic Correlations

157 boreholes provide biostratigraphic data for a basin-wide zonation scheme in Western Australia. The report compiles logs and correlations for 604 key boreholes, visualized in 25 correlation transects. Geoscience Australia Data produced this tectonostratigraphic framework, last updated in March 2026, to enhance understanding of regional geology and groundwater systems.

Use Cases

• Correlating geological units across the basin based on biostratigraphic zonation and log patterns.
• Modeling aquifer extent and variability for groundwater assessments using the hydrostratigraphic classification.
• Refining regional sequence stratigraphy by grouping units into defined supersequences (e.g., L-K, J, I, H).
• Integrating diverse data types like chemostratigraphy and geochronology for a unified tectonostratigraphic framework.

Strengths

• Compiles data from 157 boreholes to create a basin-wide consistent zonation scheme.
• Includes stratigraphic correlations for 604 of 805 key boreholes, visualized in 25 correlation transects.
• Integrates multiple data sources including biostratigraphy, borehole logs, and past research for a robust framework.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
• Data may reflect geographic bias inherent to the specific boreholes selected within the Canning Basin.
