Geochemical evidence from the Lennard Shelf and Barbwire Terrace in Western Australia's Canning Basin indicates photic zone euxinia prevailed during the Givetian–Frasnian. Biomarker assemblages from oils and rock extracts, including hopane, sterane, and carotenoids abundances, are used to correlate petroleum sources. The dataset is associated with a 2018 study published in Marine and Petroleum Geology.
Use Cases
- Correlating petroleum sources based on biomarker assemblages like hopane and sterane abundances mentioned in the description
- Analyzing the relationship between nutrient supply, algal activity, and episodic photic zone euxinia
- Studying the impact of restricted marine settings on persistent euxinia and bacterial predominance
- Investigating the link between widespread photic zone euxinia and organic-rich shale deposition
Strengths
- Data is linked to a peer-reviewed 2018 publication in Marine and Petroleum Geology with a specific DOI
- Geochemical evidence is described for two distinct geographic margins: 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
