Barnicarndy 1 Core: Ordovician Microfossils and Biomarkers from Western Australia

42 drill core samples from the Barnicarndy 1 well in Western Australia yielded a plethora of acid-resistant, organic-walled microfossils. Seven samples with the highest organic content were analyzed for molecular biomarkers and stable isotopes. This dataset records the evolution of terrestrial and marine organisms in the early Ordovician Nambeet Formation.

Use Cases

• Classifying microfossil assemblages based on the described abundance of acid-resistant, organic-walled specimens.
• Reconstructing paleo-redox conditions during deposition based on biomarker and stable isotope analysis.
• Correlating stratigraphic sequences using the described fossil content reflective of an open marine environment.
• Studying the type of preserved organic matter in organically poor calcareous shales.

Strengths

• Analysis of 42 drill core samples provides a substantial sample set.
• Seven samples underwent detailed molecular biomarker and stable isotopic analysis.
• Data is tied to a specific geological formation and well (Nambeet Formation, Barnicarndy 1).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; the abstract was presented in 2022.
