Tectonic and Stratigraphic History of the Perth Basin with Palaeogeographic Maps

A newly compiled structural elements map and chronostratigraphic section illustrate the basin's complex development through at least two major extensional faulting periods. The Australian Ocean Data Network provides this analysis, which includes palaeogeographic maps in a plate reconstructed setting. The dataset was last updated on April 10, 2026.

Use Cases

• Modeling basin evolution based on described periods of extensional faulting and sag phases.
• Assessing hydrocarbon source rock potential based on described formations like the Kockatea Shale and Cattamarra Coal Measures.
• Reconstructing palaeogeography based on the series of plate-reconstructed maps.
• Analyzing the continent-ocean transition obscured by extensive Valanginian volcanism.

Strengths

• Includes a newly compiled structural elements map and chronostratigraphic section.
• Covers a complex geological history spanning from the Late Carboniferous to the Recent.
• Identifies specific source rock formations like the Irwin River and Yarragadee Formations.

Limitations

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