Barnicarndy 1 Core: Ordovician Microfossils and Biomarkers from Western Australia

Western Australia's Canning Basin contains core samples from the Barnicarndy 1 well drilled in 2019. The dataset includes analysis of 42 drill core samples for acid-resistant microfossils and 7 samples for molecular biomarkers and stable isotopes from the early Ordovician Nambeet Formation. This work was presented at the 2022 Australian Organic Geochemistry Conference.

Use Cases

• Reconstructing early Ordovician marine paleoenvironments based on microfossil assemblages mentioned in the description
• Analyzing ancient redox conditions and organic matter type based on molecular biomarker and stable isotope data
• Correlating stratigraphic sections in the Canning Basin using the described fossil record
• Studying the evolution of terrestrial and marine organisms in the early Ordovician as indicated by the dataset title

Strengths

• Analysis of 42 drill core samples provides a substantial sample set for microfossil study
• Molecular biomarker and stable isotope data from 7 core samples with the highest organic content
• Specific average total organic carbon content of 0.17 wt% is provided for context

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to a single core from the Canning Basin
