Tectonic and Stratigraphic History of the Perth Basin with Palaeogeographic Maps

Geoscience Australia Data compiled a structural elements map and chronostratigraphic section to illustrate the tectono-stratigraphic development of southwestern Australia. The description details at least two major extensional faulting periods, from the Late Carboniferous to Early Cretaceous, and identifies multiple known or inferred hydrocarbon source rock formations. The dataset was last updated on 2026-04 20.

Use Cases

• Modeling basin evolution based on described periods of extensional faulting and sag phases.
• Assessing hydrocarbon source rock potential based on identified Permian to Jurassic formations.
• Reconstructing palaeogeography based on the series of plate-reconstructed maps.
• Analyzing the continent-ocean transition obscured by extensive Valanginian volcanism.

Strengths

• Description provides detailed geological timeline from Late Carboniferous to Recent.
• Identifies specific source rock formations (e.g., Irwin River, Cattamarra Coal Measures) for hydrocarbon analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
