Tectonic and Stratigraphic History of the Perth Basin, Australia

A series of palaeogeographic maps illustrate the tectono-stratigraphic development of southwestern Australia in a plate reconstructed setting. The area experienced at least two periods of extensional faulting in the Late Carboniferous-Early Permian and Late Jurassic-Early Cretaceous, with oceanic crust growth from the Barremian onward. The dataset was compiled by Geoscience Australia and includes known or inferred source rocks from the Permian to Jurassic periods.

Use Cases

• Model basin evolution based on described periods of extensional faulting and sag phases.
• Assess hydrocarbon potential based on identified source rock formations like the Irwin River and Kockatea Shale.
• Reconstruct palaeogeography based on the series of plate-reconstructed maps.
• Analyze the impact of volcanism and rifting episodes on basin structure.

Strengths

• Includes a newly compiled structural elements map and chronostratigraphic section.
• Identifies specific geological periods and formations, such as the Late Jurassic-Early Cretaceous rifting episode and the Carynginia Formation.
• Covers a complex geological history spanning from the Late Carboniferous to the Recent.

Limitations

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