The Cape Range structure, Western Australia Pt 1: Stratigraphy and structure Pt 2: Micropa

The Cape Range structure in Western Australia's North-West Cape peninsula is a closed anticline in Tertiary limestones. The report describes its dimensions, stratigraphy, and potential for oil drainage, based on investigations likely conducted by geological surveys. It was last updated on the platform in April 2026.

Use Cases

• Analyzing the structural dimensions and closure of a large anticline based on the described 80-mile length and 1200-foot vertical closure.
• Studying Tertiary stratigraphy and sediment thickness based on the described five formations and their compositions.
• Assessing hydrocarbon potential based on the described unrestricted oil drainage on specific flanks of the structure.
• Correlating regional geology based on the described context within the Carnarvon Basin and Indo-Pacific geosyncline.

Strengths

• Provides specific structural dimensions: at least 80 miles long, 20 miles wide, with 1200 feet of vertical closure.
• Describes detailed stratigraphy, including five Tertiary formations with named units and thicknesses (e.g., Mandu Calcarenite: 265 feet).
• Includes inferred sediment thicknesses for underlying Cretaceous, Eocene, and older periods.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data format is PDF/HTML, which may require extraction for computational analysis.
