A geological dataset illustrating the tectono-stratigraphic development of southwestern Australia in a plate reconstructed setting. It includes a series of palaeogeographic maps based on a newly compiled structural elements map and chronostratigraphic section for the Perth Basin. The data was published by Geoscience Australia and was last updated on April 30, 2026.
Use Cases
- Modeling basin evolution based on described periods of extensional faulting and sag basin development.
- Assessing petroleum source rock potential based on described formations like the Irwin River, Sue Group, and Kockatea Shale.
- Reconstructing palaeogeography and depositional centre migration through time as described in the summary.
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 geological formations and their inferred resource potential.
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 in PDF and HTML formats, which may require extraction for computational analysis.
