Description
A palynological reconnaissance study from the Australian Government's Exploring for the Future program. The dataset focuses on acid-resistant organic-walled microfossils recovered from 42 samples within the Lower Ordovician Nambeet Formation in the Barnicarndy 1 stratigraphic well, located in the Canning Basin of Western Australia. Digital images accompany the record, showing a diverse suite of microfossils including acritarchs, cryptospores, and chitinozoans.
Use Cases
Biostratigraphic correlation of Lower Ordovician rock units based on identified microfossil assemblages.
Assessing thermal maturity of organic matter based on observed palynomorph color ranges.
Studying early life forms and depositional environments from the diverse microfossil suite described.
Evaluating microfossil preservation and yield for regional geological studies.
Strengths
Includes digital images of all identified microfossil types mentioned in the description.
Based on 42 samples from a fully cored stratigraphic well section (1354.80–2435.04 mRT).
Identifies a diverse suite of microfossils including acritarchs, cryptospores, and chitinozoans.
Allows correlation with assemblages from other wells in the Canning Basin (Samphire Marsh 1, Acacia 2).
Limitations
Microfossil yield per sample is described as mostly low, with preservation ranging from poor to good.
Row count and column-level documentation are unknown, limiting suitability assessment.
No palynomorphs were recovered from the Barnicarndy, Yapukarninjarra, and Yeneena Basin formations intersected in the well.
