Mesozoic Rock Samples Dredged from the Northern Exmouth Plateau and Rowley Terrace

Forty-two major Mesozoic lithofacies types were recovered from a dredging program conducted by AGSO in 1990 on the northern Exmouth Plateau and Rowley Terrace margin offshore northwest Australia. The data provides geological control for seismic interpretations, detailing sedimentary and volcaniclastic rocks from the Late Triassic to Early Cretaceous. It was published by Geoscience Australia Data and last updated in March 2026.

Use Cases

• Modeling Late Triassic reefal petroleum reservoir potential based on described carbonate facies.
• Analyzing depositional environment changes from shelf carbonates to fluvial siliciclastics based on described stratigraphic sequences.
• Correlating southern Tethyan margin facies based on described foraminiferal and ostracod microfaunas.
• Interpreting seismic data for the Rowley Sub-basin based on the geological control provided by the dredged samples.

Strengths

• Recovered 42 distinct Mesozoic lithofacies types.
• Provides direct geological control for a specific offshore region.
• Includes temporal analysis spanning from Late Triassic to Early Cretaceous.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
