Stable isotope ratios (D/H and O18/O16) from thermal waters in Matupi Harbour and Sulphur Creek indicate a mixed meteoric and marine origin. The Australian Ocean Data Network provides this data, which includes chemical analyses of Fe, Mn, and Zn to assess leaching potential and rock reactivity. These findings challenge previous hypotheses based solely on anion ratios and trace metals.
Use Cases
- Modeling hydrothermal fluid mixing based on stable isotope ratios mentioned in the description
- Assessing the leaching potential of geothermal fluids based on elevated Fe, Mn, and Zn values
- Re-evaluating hypotheses of geothermal water origin using combined isotope and chemical data
- Mapping the influence of meteoric versus marine water in shoreline and inland thermal systems
Strengths
- Data includes stable isotope ratios (D/H and O18/O16) for distinct geographic areas
- Chemical analyses include trace metals (Fe, Mn, Zn) to assess rock-fluid interactions
- Dataset is hosted by the authoritative Australian Ocean Data Network
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- File formats are PDF and HTML, which may require extraction for tabular analysis
