Aeolianite Analysis in the Jurassic Jurgurra Sandstone, Canning Basin

An environmental analysis from 1976 examines evidence of aeolian (wind) deposition in the Jurassic Jurgurra Sandstone, a unit previously considered marine. The note describes a specific exposure near Geegully Creek, Western Australia, with an average vertical thickness of about 5 meters. This geological report is provided by Geoscience Australia Data.

Use Cases

• Classifying depositional environments based on described aeolian features and cross-bedding.
• Correlating subsurface geological units based on described tentative correlation with the Wallal Sandstone.
• Analyzing regional sediment thickness based on the reported 120m to 369m thickness range of the Wallal Sandstone.
• Studying fossil content and paleoenvironments based on mentions of fossil wood, clay pellets, and marine bivalves.

Strengths

• Provides specific geographic coordinates for the studied exposure and reference wells.
• Includes precise thickness measurements, such as the 5m exposed section and the 369m maximum recorded thickness of the Wallal Sandstone.
• Cites foundational geological literature and correlations (e.g., Brunnschweiler 1954, McWhae 1961).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to a single 1976 field study.
