Roadian–Wordian Permian Zircon U-Pb and Palynology Ages from the Canning Basin

U–Pb zircon dating results from middle Permian tuffs in the Canning Basin of Western Australia, revealing an apparent conflict with established spore-pollen zonation. The dataset includes ages such as 267.04 ± 0.14 Ma from the Pittston SD-1 drillhole and comparative data from other core holes. It was published by Mory et al. in 2017 and is hosted by Geoscience Australia.

Use Cases

• Calibrating Permian spore-pollen biozones based on U–Pb zircon ages.
• Investigating facies-dependent biases in palynological assemblages mentioned in the description.
• Comparing geochronological data from non-marine and marginal-marine depositional environments.
• Re-evaluating the age of the Microbaculispora villosa and Dulhuntyispora granulata zones.

Strengths

• Includes high-precision CA-IDTIMS U–Pb zircon dates, such as 267.04 ± 0.14 Ma.
• Provides comparative data from core holes spanning 350–400 km within the Canning Basin.
• Dataset is associated with a peer-reviewed publication in the Australian Journal of Earth Sciences.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
