9000 km2 of offshore southwest Australia's continental slope is covered by seismic data for the Bremer Basin. The basin likely contains a 10 km thick sedimentary pile with Late Jurassic to Tertiary deposits. The Australian Ocean Data Network provides this geological assessment, last updated in April 2026.
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 using the described Late Jurassic to Tertiary deposit layers.
- Compare structural trends with the adjacent Perth Basin based on the mentioned influence of older extension events.
Strengths
- The basin area is precisely quantified at 9000 km2.
- Sedimentary pile thickness is estimated at 10 km.
- Water depth range is specified as 200-3000 m.
- A grid of seismic data covers the basin, as stated in the description.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- The hydrocarbon potential is described as 'currently unknown' and inferred by analogy.
