Late Devonian Photic Zone Euxinia and Oil Source Rock Data from the Canning Basin

Geochemical data from the Canning Basin in Western Australia investigates photic zone euxinia during the Givetian–Frasnian stages of the Late Devonian period. The dataset includes biomarker assemblages from rock extracts and oils, used to correlate petroleum source rocks. It was published in Marine and Petroleum Geology in 2018 and is hosted by Geoscience Australia Data.

Use Cases

• Correlating oil samples to source rocks based on hopane, sterane, and carotenoid abundances.
• Modeling the development of photic zone euxinia in relation to nutrient supply and basin restriction.
• Investigating the link between widespread anoxia, mass extinctions, and organic-rich shale deposition.

Strengths

• Data is tied to a specific peer-reviewed study published in Marine and Petroleum Geology.
• Analysis covers two distinct geographic margins within the Canning Basin: the Lennard Shelf and Barbwire Terrace.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
