Stratigraphy and Structure of the Carnarvon Basin

A geological survey describes the stratigraphy and structure of the Williambury and Moogooree one-mile map areas in the Carnarvon sedimentary basin. The report details rock formations from the Pre-Cambrian basement through Devonian, Carboniferous, Permian, Cretaceous, and Tertiary periods, including thicknesses and unconformities. It was published by the Australian Ocean Data Network.

Use Cases

• Analyze stratigraphic column thicknesses, such as the 4750-foot Devonian sequence, for basin modeling.
• Study structural geology features and unconformities described between Permian and Cretaceous systems.
• Map the distribution and maximum 80-foot thickness of widespread Tertiary arenaceous deposits.
• Investigate Tertiary lateritisation processes, including the silicified cap ranging up to 30 feet thick.
• Examine the post-laterite deposit of 12 feet of probable fresh-water limestone noted in the region.

Strengths

• Report provides specific stratigraphic thickness measurements, such as 4750 feet for Devonian sediments.
• Covers a defined geographic area corresponding to two one-mile map sheets for focused analysis.

Limitations

• Data is presented in a descriptive report format (PDF/HTML), not as structured, machine-readable data tables.
• The sample size or spatial resolution is constrained to the two specified map areas.
• Temporal coverage is based on geological epochs, not contemporary time-series data.
