Seismic Facies Mapping of the Mentelle Basin Post-Rift Succession

The Mentelle Basin, located about 200 km southwest of Perth on Australia's southwestern margin, is the subject of this seismic facies study. Geoscience Australia acquired new 2D seismic data in 2008-09, which was used to analyze the post-rift depositional history from the Valanginian to the Campanian periods. The study identifies fourteen distinct seismic facies and integrates data from stratigraphic wells DSDP 258 and DSDP 264.

Use Cases

• Mapping basin-scale depositional environments based on seismic reflection characteristics described in the study.
• Analyzing the evolution of sedimentary facies from syn-rift volcanism to post-rift thermal subsidence.
• Correlating seismic facies with lithological data from DSDP wells to constrain age and rock properties.
• Modeling sediment transport and accommodation space creation in a frontier deep-water basin.

Strengths

• Based on new 2D seismic data acquired in 2008-09, providing a modern analysis.
• Identifies fourteen distinct seismic facies based on reflection continuity, amplitude, frequency, and geometry.
• Integrates age and lithological constraints from two Deep Sea Drilling Project (DSDP) wells.
• Provides specific sedimentation rate data for the Albian period (>45 m/my).

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 of the Mentelle Basin.
