Late Devonian Photic Zone Euxinia and Oil Correlation in the Canning Basin

Geochemical data from the Canning Basin in Western Australia, focusing on the Givetian–Frasnian stages of the Late Devonian. The dataset, associated with a 2018 research article, provides insights into photic zone euxinia and its role in forming petroleum source rocks. It includes biomarker analyses from oil fields and rock extracts to establish correlations.

Use Cases

• Modeling the development of photic zone euxinia based on geochemical evidence from the Lennard Shelf and Barbwire Terrace.
• Correlating petroleum sources using biomarker assemblages such as hopane, sterane, and carotenoid abundances.
• Assessing the impact of nutrient supply and restricted marine settings on persistent anoxia and bacterial predominance.
• Evaluating the petroleum potential of Late Devonian shales in the Fitzroy Trough based on the extent of anoxia.

Strengths

• Data is linked to a peer-reviewed research article published in Marine and Petroleum Geology in 2018.
• Analysis covers two distinct geographic margins within the Canning Basin: the Lennard Shelf and the Barbwire Terrace.
• Includes biomarker data from specific oil fields and wells (e.g., Blina-1, Mirbelia-1) and rock extracts from named formations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
