Aeolianite Analysis in the Jurassic Jurgurra Sandstone, Western Australia

An environmental analysis note from 1976 examines an exposure of the Jurassic Jurgurra Sandstone about 20 km north of its type locality. The document, sourced from the Australian Ocean Data Network, presents evidence of aeolian deposition in a section with an exposed vertical thickness averaging about 5 meters. It discusses correlations with the subsurface Wallal Sandstone, which reaches a maximum recorded thickness of 369 meters.

Use Cases

• Study aeolian depositional environments based on the described cross-bedded sandstone and fluted surfaces.
• Correlate surface and subsurface Jurassic units based on the tentative correlation with the Wallal Sandstone.
• Analyze paralic and marine transgressive deposits based on the described fossil content and historical interpretations.

Strengths

• Provides specific location coordinates and a detailed geological context from a 1976 mapping project.
• Includes concrete thickness measurements for the Wallal Sandstone (up to 369 m) and the exposed section (about 5 m).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
