Late Cainozoic Sequence of Southeast South Australia and Pleistocene Sea-Level Changes

A recent drilling program in southeast South Australia provides new insight into the late Cainozoic sequence. The data likely contains information on sediment facies and sea-level changes over a period of 690,000 years or less, resulting in a 100 km seaward progradation of the shoreline between Naracoorte and Robe. The dataset is provided by Geoscience Australia Data and was last updated in May 2026.

Use Cases

• Reconstructing past sea-level stands based on the described regressive sequence of sandy and interdunal facies.
• Modeling shoreline progradation over a 690,000-year period using the described 100 km seaward shift.
• Analyzing sediment depositional environments transitioning from marine to aeolian conditions.
• Correlating regional uplift and volcanic activity with sedimentary sequences.

Strengths

• Covers a significant time span of at least 690,000 years.
• Documents a substantial geographic shift of 100 km in shoreline progradation.
• Suggests evidence for at least 20 major high sea-level stands during the studied period.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified despite the 2026 update date.
