Jurgurra Sandstone Aeolianite Analysis in Western Australia

A geological note presents an environmental analysis of an exposure of the Jurassic Jurgurra Sandstone in the Canning Basin. The analysis, conducted during 1976 mapping, found evidence of aeolian deposition in a section about 20 km north of the type locality. The data is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Classifying depositional environments based on described aeolian features.
• Correlating subsurface units like the Wallal Sandstone based on thickness data from exploration wells.
• Analyzing the transgressive deposits of a Jurassic marine advance as mentioned in the description.

Strengths

• Includes specific location coordinates for the examined exposure and referenced exploration wells.
• Provides concrete thickness measurements for the Wallal Sandstone (120 m to 369 m).
• References historical geological definitions and correlations from 1954 and 1961.

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/HTML formats, which may require extraction for computational analysis.
