Geology of the Exmouth and Wallaby Plateaus: Seismic and Rock Sample Data

Geological data from the margins of the Exmouth and Wallaby Plateaus off northwest Australia. The dataset includes information from 29 sampling stations on the Exmouth Plateau and 12 stations on the Wallaby Plateau and Cuvier Abyssal Plain, derived from seismic profiles and rock dredging. It was published by Geoscience Australia and last updated in April 2026.

Use Cases

• Reconstructing the geological history of the northern Exmouth Plateau margin based on described Triassic to Tertiary rock sequences.
• Assessing volcanic activity and plateau formation on the Wallaby Plateau based on described interbedded basalts and volcaniclastic deposits.
• Evaluating petroleum potential in offshore basins based on described coal-measure and carbonate sequences.
• Correlating seismic stratigraphy with physical rock samples from the described dredging stations.

Strengths

• Data is derived from 41 specific sampling stations (29 on Exmouth, 12 on Wallaby/Cuvier).
• Description provides detailed lithological information for multiple facies associations (A-E).
• Includes specific geological timeframes, such as Middle/Late Triassic and Early Jurassic sequences.

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 the specific study area off northwest Australia.
