Seismic Facies Mapping of the Mentelle Basin Post-rift Succession

Fourteen seismic facies were identified in the Mentelle Basin based on new 2D seismic data acquired by Geoscience Australia in 2008-09. The dataset describes the post-rift depositional history from the Valanginian to the Campanian, using stratigraphic constraints from wells DSDP 258 and DSDP 264. It is hosted by the Australian Ocean Data Network on data_gov_au.

Use Cases

• Modeling post-rift sedimentary basin evolution based on seismic facies and stratal geometries.
• Analyzing deep-water depositional environments based on described channel, mound, and basin-fill facies.
• Correlating seismic sequences with age-equivalent units based on comparisons to the south Perth Basin.
• Studying syn-depositional volcanism and thermal subsidence patterns based on the described stratigraphic history.

Strengths

• Analysis is based on new 2D seismic data acquired in 2008-09.
• Fourteen distinct seismic facies are identified and described.
• Stratigraphic constraints are provided by two DSDP wells (258 and 264).
• The study covers a long temporal range from Valanginian to Campanian periods.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data format is HTML, which may require extraction for quantitative analysis.
