Late Devonian Photic Zone Euxinia Geochemical Data from the Canning Basin

Geochemical evidence from the Canning Basin in Western Australia indicates photic zone euxinia prevailed during the Givetian–Frasnian stages of the Late Devonian. The data likely contains biomarker assemblages, including hopane, sterane, and carotenoid abundances, from rock extracts and oils used to study anoxia and petroleum source rock formation. This dataset was published in Marine and Petroleum Geology, Volume 93, 2018, and is hosted by the Australian Ocean Data Network.

Use Cases

• Correlating oil biomarkers to source rock extracts based on hopane and sterane abundances mentioned in the description
• Modeling the persistence of photic zone euxinia in a confined basin setting based on geochemical evidence
• Investigating the relationship between nutrient supply, algal activity, and episodic anoxia pulses described for the Lennard Shelf

Strengths

• Data is associated with a peer-reviewed publication in Marine and Petroleum Geology, Volume 93, 2018
• Geographic coverage includes specific sub-regions within the Canning Basin: the Lennard Shelf and Barbwire Terrace
• Analysis includes specific biomarker assemblages: hopanes, steranes, and carotenoids

Limitations

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