Mesozoic Outcrops on the Lower Continental Slope off Exmouth, Western Australia

Western Australia's Exmouth Plateau features seismic reflection profiles indicating probable Permian to Early Tertiary bedrock outcrops on the lower continental slope. The data, from Geoscience Australia, describes water depths from 1400 to 4000 meters and includes inferred rock types from pre-Late Jurassic fluvial deposits to Cainozoic foraminiferal ooze. It was last updated on 2026-05-14.

Use Cases

• Modeling petroleum potential based on inferred rock sequences and fault structures.
• Reconstructing geological evolution based on described faulting events and anticline formation.
• Planning offshore sampling campaigns to date outcrops along the southwestern margin.
• Analyzing basin formation theories based on interpretations of Late Cretaceous margin development.

Strengths

• Specific water depth range provided: 1400 to 4000 meters.
• Detailed geological interpretation of rock types and ages from Permian to Cainozoic.
• Structural features like normal faults and a major anticline are described.

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.
