Mesozoic Rock Samples from the Northern Exmouth Plateau and Rowley Terrace

42 major Mesozoic lithofacies types were recovered from a 1990 dredging program by AGSO on the northern Exmouth Plateau and Rowley Terrace. The dataset, hosted by the Australian Ocean Data Network, provides geological control for seismic interpretations and indicates Late Triassic to Early Cretaceous depositional environments. It was last updated on June 5, 2026.

Use Cases

• Modeling Late Triassic reefal petroleum reservoir potential based on described carbonate facies.
• Reconstructing paleoenvironmental conditions during the breakup of Australia and Greater India based on volcaniclastic and sedimentary sequences.
• Correlating depositional facies and microfaunas with other southern Tethyan margins for regional geological studies.

Strengths

• Contains 42 distinct Mesozoic lithofacies types.
• Provides direct geological control for seismic interpretations from a specific 1990 survey.
• Includes temporal context spanning from the Late Triassic to the Early Cretaceous.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is delivered in PDF and HTML formats, which may require extraction for computational analysis.
