1976 geological mapping of the Mount Anderson Sheet area examined an exposure of the Jurassic Jurgurra Sandstone. The Australian Ocean Data Network presents an environmental analysis of a section containing evidence of aeolian deposition, with vertical thickness averaging about 5 meters. The note correlates the unit with subsurface Wallal Sandstone, which thickens to 369 meters in the Munro No.1 well.
Use Cases
- Reconstruct Jurassic depositional environments based on described cross-bedding and fossil wood.
- Analyze aeolian versus marine sediment origins based on evidence of aeolian deposition and marine bivalves.
- Correlate subsurface and surface geological units based on tentative correlation with the Wallal Sandstone.
- Study sandstone thickness variations based on recorded thicknesses of 120 m and 369 m in exploration wells.
Strengths
- Provides specific location coordinates for the exposure described.
- References thickness data from exploration wells (120 m and 369 m).
- Includes 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 may reflect geographic bias inherent to data_gov_au.
