Cape Range Structure Geology and Micropalaeontology Report, Western Australia

The Australian Ocean Data Network hosts a geological report on the Cape Range Structure, a large anticline in Western Australia. The report details the structure's dimensions, stratigraphy, and potential for oil drainage. It was last updated on 2026-06 04.

Use Cases

• Model subsurface geology based on described stratigraphic column and formation thicknesses.
• Assess hydrocarbon potential based on described structural closure and drainage areas.
• Study regional tectonic history based on the description of sediment deposition and structural stability.
• Conduct micropalaeontological analysis based on the described fossil content in the limestone formations.

Strengths

• Provides specific structural dimensions: at least 80 miles long, 20 miles wide, with 1200 feet of vertical closure.
• Details five named Tertiary formations with thickness ranges, such as the 265-foot Mandu Calcarenite.
• Includes estimates of underlying sediment thickness, suggesting up to 18,000 feet of Paleozoic marine sediments.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF/HTML report format, not as structured tabular data.
