Mentelle Basin Post-rift Seismic Facies Mapping from 2008-09 Survey

Geoscience Australia used 2D seismic data acquired in 2008-09 to map fourteen seismic facies within the post-rift succession of the Mentelle Basin. The study provides age and lithological constraints from stratigraphic wells DSDP 258 and DSDP 264 and analyzes depositional environments from the Valanginian to Campanian periods. The dataset describes seismic reflection characteristics, stratal geometries, and inferred lithologies for this frontier basin located about 200 km southwest of Perth.

Use Cases

• Modeling post-rift basin evolution based on described seismic facies and stratal geometries.
• Correlating seismic facies to lithology using constraints from DSDP wells mentioned in the description.
• Analyzing depositional environments like channel fills, contourites, and turbidites based on the identified facies types.
• Studying syn-depositional volcanism and thermal subsidence patterns in the Valanginian to Hauterivian period.

Strengths

• Analysis is based on specific 2D seismic data acquired by Geoscience Australia in 2008-09.
• Fourteen distinct seismic facies are identified with attributes like reflection continuity, amplitude, and geometry.
• Study integrates data from stratigraphic wells DSDP 258 and DSDP 264 for age and lithological constraints.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
