Cape Range Structure Stratigraphy and Micropalaeontology, Western Australia

A geological study of the Cape Range anticline on the North-West Cape peninsula, Western Australia. The report describes a structure at least eighty miles long and twenty miles wide, with a vertical closure of 1200 feet and a closed area of 1200 square miles. It details five Tertiary formations and underlying Cretaceous to Devonian sediments, published by the Australian Ocean Data Network.

Use Cases

• Modeling hydrocarbon migration and trap geometry based on the described anticline structure and vertical closure.
• Correlating stratigraphic sequences using the described lower Miocene to Pliocene formations.
• Assessing sediment thickness and basin evolution from the described Cretaceous and older marine sediments.
• Planning geophysical surveys (gravity and seismic) to determine the shape of the structure in depth as suggested in the description.

Strengths

• Provides specific structural dimensions: at least 80 miles long, 20 miles wide, with 1200 feet of vertical closure.
• Details stratigraphic column with five named Tertiary formations and their approximate thicknesses.
• Identifies the structure as the largest in the Carnarvon Basin by vertical closure and closed area.

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, focusing solely on a specific Australian region.
