Lake Frome Geochemistry and Sediment Data from South Australia

Geochemical data from Lake Frome, a large playa lake in southeast South Australia, collected by Geoscience Australia. The dataset includes analyses of sediments and hypersaline brines from the lake and surrounding mound springs, with stratigraphic records covering approximately 17,000 years. It was last updated on 2026-04-30.

Use Cases

• Modeling metal ion transport and concentration based on hypersaline brine chemistry described in the study.
• Analyzing playa sedimentation patterns based on stratigraphic units (upper/lower sands, muds) identified from auger samples.
• Comparing the geochemical composition of different sediment types (sands vs. muds) based on major and minor element analyses.
• Studying the mixing of artesian water with lake brines based on the composition of mound springs.

Strengths

• Stratigraphic analysis provides a temporal context covering approximately 17,000 years.
• Description details specific geochemical findings, such as high sodium and chloride ion concentrations (26-34%) and the lack of minor element enrichment in brines.
• The study distinguishes between multiple sediment units and water sources, including mound springs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
