A geological dataset describing the Cape Range Structure, a large anticline in Tertiary limestones on the North-West Cape peninsula. The structure is at least eighty miles long and twenty miles wide, with a vertical closure of 1200 feet and a closed area of 1200 square miles. The data, provided by the Australian Ocean Data Network, details five Tertiary formations and discusses the potential for oil drainage.
Use Cases
- Modeling subsurface structure for hydrocarbon exploration based on described anticline dimensions and closure.
- Stratigraphic correlation using the described Tertiary limestone formations (Mandu Calcarenite, Tulki Limestone, etc.).
- Assessing basin evolution and sediment thickness based on the described Cretaceous, Eocene, and older sediment estimates.
- Planning geophysical surveys (gravity, seismic) to determine sediment thickness and deep structure shape.
Strengths
- Provides specific structural dimensions: at least 80 miles long, 20 miles wide, 1200 ft vertical closure.
- Details stratigraphic column with formation names, thicknesses (e.g., Mandu Calcarenite 265 ft), and lithology.
- Includes estimates for underlying sediment thickness, suggesting up to 18,000 feet of Permian to Devonian 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 files are in HTML and PDF formats, which may require extraction for quantitative analysis.
