Barnicarndy 1 Core: Ordovician Microfossils and Biomarkers from Canning Basin

Scientific analyses of 42 drill core samples from the Barnicarndy 1 well in Western Australia's Canning Basin. The data likely contains counts and measurements of acid-resistant, organic-walled microfossils, plus molecular biomarker and stable isotope data from seven selected samples. This work was presented at the 2022 Australian Organic Geochemistry Conference and is hosted by the Australian Ocean Data Network.

Use Cases

• Classifying early Ordovician marine microfossil assemblages based on sample analysis.
• Analyzing paleo-redox conditions during deposition using biomarker and stable isotope data.
• Correlating stratigraphic sequences in the Canning Basin using fossil content.
• Studying the type and preservation of organic matter in organically-poor calcareous shales.

Strengths

• Analysis is based on 42 physical drill core samples from a specific well.
• Includes detailed molecular (biomarker) and stable isotope data from 7 samples with the highest organic content.
• Sample context is well-defined: early Ordovician Nambeet Formation, Canning Basin, Western Australia.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The average total organic carbon content is reported as low (0.17 wt%).
