Aeolianite Analysis in Jurassic Jurgurra Sandstone, Western Australia

Geoscience Australia presents an environmental analysis of an aeolian deposit within the Jurassic Jurgurra Sandstone, based on a 1976 field examination. The report details a 5-meter-thick exposure near Geegully Creek, correlating it with the subsurface Wallal Sandstone unit, which reaches 369 meters in thickness.

Use Cases

• Analyze aeolian depositional structures and cross-bedding features described in the Jurgurra Sandstone exposure for paleoenvironmental reconstruction.
• Correlate the studied section with the Wallal Sandstone unit using reported thickness data (120m to 369m) from exploration wells for regional stratigraphic modeling.
• Map the geographic location of the exposure using provided coordinates (lat. 18° 32' 30" S, long. 123° 40' 55" E) for geological GIS projects.

Strengths

• Analysis is grounded in specific field observations from a documented 1976 geological mapping campaign.
• Provides precise geographic coordinates and a measured vertical exposure thickness of about 5 meters.
• Includes comparative thickness data for the correlated Wallal Sandstone, with a maximum recorded thickness of 369 meters.

Limitations

• Dataset is a static geological note from a single 1976 field examination, not a continuously updated or tabular data resource.
• Core data is presented in narrative PDF/HTML format, lacking structured, machine-readable columns or sample data for direct computational analysis.
• Focus is on a single localized exposure, limiting broader statistical or regional analysis without supplementary datasets.
