Lake Eliza Sediment Analysis for Oil Shale Genesis Comparison

Lake Eliza is a hypersaline coastal lake in southeast South Australia. The dataset contains a study comparing sediment composition from its protected western and exposed eastern margins, suggesting a new depositional model for lamosite oil shales analogous to the Green River Formation. The data is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling oil shale genesis based on comparisons to the Green River Formation mentioned in the description.
• Analyzing sediment composition differences based on the described organic content and mineralogy of protected versus exposed lake margins.
• Studying hypersaline lake biogeochemistry based on the described non-marine biota and seasonal salinity changes.
• Comparing modern sedimentary analogs for ancient lacustrine deposits based on the described similarity to the Wilkins Peak Member.

Strengths

• Study provides a specific modern analog for the Green River Formation's Wilkins Peak Member.
• Description details concrete environmental factors: salinity rises from <100 to >360%, and a shift from winter rainfall to summer drought.
• Explicitly compares two distinct sedimentary facies: a fine carbonate, high-organic western shore and a quartz-carbonate sand eastern shore.

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 computational analysis.
