Lake Frome Geochemistry and Sediment Data from South Australia

Stratigraphic analysis from shallow auger holes shows sediment accumulation over the last 17000 years. The dataset contains geochemical analyses of clastic sediments and brines from Lake Frome, a hypersaline playa lake, published by the Australian Ocean Data Network. The data was last updated on 2026-06-27.

Use Cases

• Modeling brine evolution and ion concentration based on sodium and chloride data.
• Analyzing stratigraphic units and sediment provenance based on major and minor element concentrations.
• Studying the geochemical differences between sandy and muddy lake sediments.
• Investigating metal ion mobility, such as lead leaching as soluble chloride complexes.

Strengths

• Analysis covers a specific 17000-year temporal window for sediment accumulation.
• Includes data on both surface and sub-surface hypersaline waters with salinity percentages (26 to 34 percent).
• Sediment analysis distinguishes between three informal stratigraphic units: upper sand, lower sand, and mud.

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, focusing on a single lake system.
