Tectonic and Stratigraphic History of the Perth Basin in Australia

The southwestern corner of Australia's tectono-stratigraphic development is illustrated in a plate reconstructed setting. The dataset includes palaeogeographic maps based on a structural elements map and chronostratigraphic section for the Perth Basin, compiled by the Australian Ocean Data Network. The record was last updated on 2026-05 05.

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 Irwin River and Kockatea Shale.
• Reconstructing palaeogeography based on the plate reconstruction and map series mentioned in the description.
• Analyzing rift history based on the described Late Jurassic-Early Cretaceous and Late Carboniferous-Early Permian episodes.

Strengths

• Includes a newly compiled structural elements map and chronostratigraphic section.
• Describes specific geological time periods and events, such as rifting at ~132.5 Ma.
• Identifies known or inferred source rocks across multiple formations (e.g., Irwin River, Sue Group).

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.
