A 2017 study presents U–Pb zircon dating and palynological data from the middle Permian Canning Basin in Western Australia. The data reveals an apparent age conflict of 1.7 million years between tuffs in non-marine and marginal-marine facies, challenging established spore-pollen zonation. The dataset is associated with Geoscience Australia and the cited research article.
Use Cases
- Calibrating Permian spore-pollen biozones based on reported U–Pb zircon ages.
- Analyzing facies-dependent biases in palynological assemblages based on the described non-marine vs. marginal-marine comparison.
- Investigating age discrepancies in stratigraphic records based on the 1.7-million-year conflict highlighted in the description.
- Studying the geological history of the Canning Basin using the provided tuff and intrusive sill age data.
Strengths
- Includes high-precision CA-IDTIMS U–Pb zircon ages with a reported uncertainty of ±0.14 Ma.
- Provides specific geographic context for samples from the Pittston SD-1 drillhole and other core holes 350–400 km away.
- Directly links geochronological data to palynological zonation (Microbaculispora villosa Zone, Dulhuntyispora granulata Zone).
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/temporal bias inherent to the specific drill cores and facies described.
