Mesozoic Outcrop Seismic Data for Exmouth Plateau Slope

Seismic reflection profiles over the southwestern margin of the Exmouth Plateau, Western Australia, indicate bedrock outcrops from the Permian to Early Tertiary periods. The data, provided by the Australian Ocean Data Network, describes geological structures and rock types in water depths from 1400 to 4000 meters. The dataset was last updated in April 2026.

Use Cases

• Identify potential hydrocarbon reservoirs by analyzing the distribution of pre-Late Jurassic fluvial and deltaic sandstone features.
• Model fault systems and structural evolution using data on north-northeasterly trending normal faults and a major anticline.
• Correlate regional stratigraphy by tying seismic profiles to the Northwest Shelf stratigraphic sequence for age dating.
• Assess seabed geology and outcrop locations from interpreted data on rock cropping along the lower continental slope.

Strengths

• Data covers a significant water depth range from 1400 to 4000 meters.
• Provides interpreted geological sequence spanning from Permian to Early Tertiary age.
• Includes analysis of major structural features like normal faults and an anticline.

Limitations

• No raw columnar or sample data is available, only interpreted descriptions in report format.
• The geological interpretations, including rock types and ages, are described as tentative.
• Primary data format is PDF/HTML, limiting direct machine analysis without extraction.
