Barnicarndy 1 Core: Early Ordovician Microfossils and Biomarkers from Western Australia

Western Australia's Canning Basin provides the location for this dataset of organic-walled microfossils and molecular fossils from the early Ordovician Nambeet Formation. It includes data from 42 drill core samples, with seven analyzed for biomarkers and stable isotopes. The data was published by Geoscience Australia and presented at the 2022 Australian Organic Geochemistry Conference.

Use Cases

• Classifying early Ordovician marine microfossil assemblages based on acid-resistant organic-walled specimens.
• Analyzing paleoenvironmental redox conditions based on molecular biomarker and stable isotope data.
• Correlating sediment depositional environments using fossil content and geochemical signatures described in the study.

Strengths

• Data is derived from 42 drill core samples, providing a material basis for analysis.
• Seven core samples with the highest organic content were analyzed for detailed biomarker and stable isotope composition.
• The dataset is associated with a specific scientific conference presentation (2022 Australian Organic Geochemistry Conference).

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%), which may limit certain analyses.
