Aeolianite Analysis in the Jurassic Jurgurra Sandstone, Canning Basin, Western Australia

An environmental analysis of a 5-meter-thick exposure of the Jurassic Jurgurra Sandstone, examined during 1976 geological mapping in the Canning Basin. The note, published by Geoscience Australia, presents evidence of aeolian deposition in a unit previously considered marine. The nearby Wallal Sandstone subsurface unit reaches a maximum recorded thickness of 369 meters.

Use Cases

• Reconstructing paleoenvironments based on described aeolian depositional evidence.
• Correlating surface and subsurface stratigraphic units based on the tentative correlation with the Wallal Sandstone.
• Analyzing sedimentary facies based on descriptions of cross-bedding, fossil wood, and clay pellets.
• Studying the Jurassic marine transgression in the Canning Basin based on the paralic origin interpretation.

Strengths

• Provides specific location coordinates (latitude and longitude) for the examined exposure and referenced wells.
• Includes concrete thickness measurements for the exposure (5 m) and the correlated subsurface unit (up to 369 m).
• Cites foundational geological literature (Brunnschweiler, 1954; McWhae, 1961) for unit definitions and correlations.

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 as a PDF/HTML note, not as a structured, machine-readable dataset.
