A 690,000-year geological sequence from southeast South Australia documents shoreline progradation and sea-level changes. The data, from a drilling program by Geoscience Australia, includes sediment facies from beach, marine, aeolian, and lacustrine environments. It suggests at least 20 major high sea-level stands during the late Cainozoic period.
Use Cases
- Modeling past sea-level changes based on the described regressive sequence and high sea-level stands.
- Analyzing sedimentary facies transitions based on described beach, marine, aeolian, and lacustrine deposits.
- Studying regional geological uplift and volcanic activity in the Mount Gambier-Mount Burr area mentioned in the description.
- Correlating geological timelines using the described 690,000-year sequence between Naracoorte and Robe.
Strengths
- Covers a defined 690,000-year geological period.
- Documents a 100 km seaward shoreline progradation.
- Identifies at least 20 major high sea-level stands.
- Describes multiple sediment facies (beach, marine, aeolian, lacustrine).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is presented in PDF/HTML formats, which may require extraction for analysis.
