New 2D seismic data acquired in 2008-09 by Geoscience Australia was used for a seismic facies study of the post-rift succession in the Mentelle Basin. The study identified fourteen seismic facies based on reflection characteristics and provides analysis of depositional environments from the Valanginian to the Albian period. The dataset is hosted by the Australian Ocean Data Network.
Use Cases
- Analyze post-rift basin evolution based on identified seismic facies and stratal geometries.
- Model depositional environments based on descriptions of channel fills, turbidites, and progradational wedges.
- Correlate stratigraphy using age and lithological constraints from DSDP wells 258 and 264.
- Study syn-depositional volcanism and thermal subsidence patterns described for the Valanginian to Hauterivian period.
Strengths
- Based on new 2D seismic data acquired in 2008-09, providing a modern analysis.
- Identifies fourteen distinct seismic facies with detailed reflection characteristic descriptions.
- Incorporates age and lithological constraints from two DSDP stratigraphic wells.
- Provides a detailed depositional history spanning from the Valanginian to the Albian period.
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 data_gov_au, focusing on a single basin.
