Cape Range Structure Geology and Micropalaeontology, Western Australia

A geological report on the Cape Range anticline in Western Australia, detailing its stratigraphy and micropalaeontology. The structure is at least eighty miles long and twenty miles wide, with a vertical closure of 1200 feet. The dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Analyze hydrocarbon potential based on descriptions of vertical closure and drainage areas.
• Study Tertiary stratigraphy based on the described Mandu Calcarenite, Tulki Limestone, and other formations.
• Model subsurface sediment thickness based on inferred Cretaceous, Eocene, and older marine sediment depths.
• Investigate tectonic stability based on comparisons with the thicker sediments of the Indonesian geosyncline.

Strengths

• Detailed quantitative dimensions: structure is at least 80 miles long, 20 miles wide, with 1200 ft vertical closure.
• Specific stratigraphic column with five named Tertiary formations and their thicknesses.
• Provides inferred sediment thicknesses for underlying Cretaceous, Eocene, and older strata.

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.
