Cape Range Anticline Stratigraphy and Micropalaeontology Report

A geological report details the Cape Range anticline, a major fold structure in Western Australia's North-West Cape peninsula. The Australian Ocean Data Network published this analysis, which describes the structure as at least eighty miles long with a vertical closure of 1200 feet. It documents five Tertiary limestone formations and discusses the basin's potential for oil and gas.

Use Cases

• Analyze the Mandu Calcarenite, Tulki Limestone, and Trealla Limestone formations for stratigraphic correlation and depositional environment modeling.
• Assess hydrocarbon potential by evaluating the structure's 1200-foot vertical closure and 1200-square-mile closed area for trap volume calculations.
• Study micropalaeontological data to date the lower Miocene (e-stage and f1-stage) sediments and reconstruct paleoenvironments.
• Model basin evolution using described sediment thicknesses, including up to 18,000 feet of possible Paleozoic marine sediments beneath the Miocene.
• Plan geophysical surveys (gravity, seismic) based on the report's recommendations to determine sediment thickness and deep structure shape.

Strengths

• Report provides specific structural dimensions: 80 miles long, 20 miles wide, 1200 ft vertical closure.
• Includes detailed stratigraphic column with five named Tertiary formations and their thicknesses (e.g., Mandu Calcarenite 265 ft).
• Discusses sediment thickness estimates ranging from 3,000 feet of Cretaceous/Eocene to up to 18,000 feet of Paleozoic strata.

Limitations

• Primary data is contained in a PDF/HTML report, not a structured, machine-readable dataset.
• No sample data, column definitions, or row counts are provided for quantitative analysis.
• The report's original publication date is not provided, potentially making the geological assessment dated.
