Evidence for a mid-Cretaceous source for southern Australian asphaltites is presented, based on geochemical and carbon isotopic comparisons. The dataset likely contains geochemical signatures such as carbon isotopes, methylsteranes, norsteranes, and metalloporphyrins. The article was prepared for the Eastern Australian Basins Symposium in 2001.
Use Cases
- Identify hydrocarbon source rock age based on biomarker comparisons mentioned in the description
- Model paleo-depositional environments based on metalloporphyrin and carbon isotope signatures
- Correlate offshore asphaltites with onshore source rock analogues using geochemical data
- Refine regional petroleum system models based on the genetic link between asphaltite and bitumen pyrolysis products
Strengths
- Analysis includes diverse geochemical signatures like carbon isotopes, methylsteranes, and norsteranes
- Compares asphaltites with specific Cretaceous source rock formations (Blue Whale Supersequence, Toolebuc Formation)
- Article was prepared for a professional symposium (Eastern Australian Basins Symposium 2001)
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 data_gov_au, focusing on southern Australian margin
