The Bremer Basin covers 9000 km2 offshore southwest Australia with a sedimentary pile likely 10 km thick. The Australian Ocean Data Network provides this dataset, which includes seismic data coverage and geological interpretations. The dataset was last updated on 2026-05-05.
Use Cases
- Model basin evolution based on described Jurassic-Cretaceous extension and wrenching events.
- Identify potential hydrocarbon traps based on inferred wrench-induced anticlines and stratigraphic traps.
- Assess sedimentary thickness and composition based on described Late Jurassic to Tertiary deposits.
- Analyze structural complexity based on intersecting Palaeozoic and Mesozoic basement trends.
Strengths
- Defined basin area of 9000 km2.
- Describes a likely sedimentary thickness of 10 km.
- Includes a grid of seismic data coverage.
- Provides detailed geological analogies with the Eyre Sub-basin.
Limitations
- Hydrocarbon potential is described as unknown.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to data_gov_au.
Provenance
