Southern Bonaparte Basin: Late Permian to Early Triassic Depositional History

Geoscience Australia Data published an extended abstract in 2021 analyzing the upper Permian to Lower Triassic sedimentary succession in the southern Bonaparte Basin, Australia. The study focuses on the timing, distribution, and depositional environments of formations like the Dombey, Tern, Penguin, and Mairmull, which host gas accumulations including the Blacktip field. It translates the basin's depositional history into a chronostratigraphic framework to predict petroleum system elements.

Use Cases

• Modeling marginal marine depositional systems based on described lithofacies changes from carbonate to siliciclastic formations.
• Correlating well data and biostratigraphy to understand basin evolution across the Permian–Triassic boundary.
• Predicting the character and distribution of petroleum system elements in the Petrel Sub-basin and Londonderry High based on the chronostratigraphic framework.

Strengths

• Study is based on regional-scale well correlations and an assessment of available biostratigraphic data.
• Focuses on a specific, economically significant geological interval (Late Permian–Early Triassic) in a known hydrocarbon province.
• Published in a peer-reviewed journal (The APPEA Journal) in 2021.

Limitations

• The dataset appears to be a conference abstract and journal article (PDF/HTML), not a primary data table; column-level documentation is absent.
• Row count and data scale are unknown, which may limit suitability assessment for quantitative analysis.
• Freshness should be verified; the metadata was last updated in 2026, but the core study is from 2021.
