Middle Permian Geochronology and Palynology Ages from the Canning Basin, Australia

A 2017 study by Mory et al. presents U–Pb zircon dating and palynological data from the Canning Basin, Western Australia. The dataset highlights an apparent age conflict of 1.7 million years between tuffs in non-marine and marginal-marine facies from the Roadian–Wordian stages. It was published in the Australian Journal of Earth Sciences and is hosted by the Australian Ocean Data Network.

Use Cases

• Calibrating spore-pollen zonation timelines based on conflicting CA-IDTIMS and palynology ages mentioned in the description.
• Analyzing the influence of non-marine depositional environments on palynoflora based on the facies comparison discussed.
• Investigating stratigraphic conflicts in the Roadian–Wordian stages using the reported tuff ages of 267.04 ± 0.14 Ma.
• Studying the impact of Late Triassic basaltic sills on Permian stratigraphy as noted in the description.

Strengths

• Includes high-precision CA-IDTIMS U–Pb zircon dates with a reported uncertainty of ± 0.14 Ma.
• Focuses on a specific, documented geological conflict spanning 350–400 km within the Canning Basin.
• Data is associated with a peer-reviewed publication in the Australian Journal of Earth Sciences.

Limitations

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