Groundwater samples from fractured bedrock aquifers beneath dryland salinity occurrences at Yass in the Southern Tablelands of New South Wales. The dataset, provided by Geoscience Australia Data, describes fresh to brackish waters with total dissolved solids ranging from 250 to 2250 mg/L. The chemical composition is derived from processes including water-rock interaction, ion exchange, and microbially mediated reactions.
Use Cases
- Modeling salinity genesis based on hydrochemical types and water-rock interactions described.
- Analyzing groundwater flow paths based on ion exchange and redox processes mentioned.
- Classifying groundwater origins based on the described meteoric water source and mineral dissolution.
- Studying aquifer geochemistry based on the described bedrock types (slates, shales, sandstones, dacite).
Strengths
- Specific salinity measurement range provided (250 to 2250 mg/L total dissolved solids).
- Detailed description of geological contexts (three named catchments with specific bedrock types).
- Clear explanation of three key hydrochemical processes generating the data.
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 the specific study area at Yass, NSW.
