1,500,000 km² of eastern Australia is covered by Cretaceous sedimentary rocks, described by the Australian Ocean Data Network. The description details depositional environments from freshwater to shallow marine, quartz content variations, and tectonic influences. The data likely includes geological maps or reports on the Eromanga and Surat Basins.
Use Cases
- Model depositional environments based on descriptions of freshwater to shallow marine sequences
- Analyze sediment provenance based on descriptions of quartz-rich and quartz-poor sequences
- Study paleogeographic changes based on descriptions of epicontinental sea transgressions and regressions
- Compare geological preservation based on the described 2000 m and 700 m sediment thicknesses
Strengths
- Description provides a specific spatial extent of 1,500,000 km²
- Description details specific sediment thicknesses of up to 2000 m and 700 m
- Description outlines a clear temporal framework spanning approximately 20 million years
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
