Origins of Sulphide in Sediments: Geochemical Processes and Modern Analogues

Geoscience Australia Data published a journal article on the origins of sulphide in sedimentary ore deposits, comparing mantle-derived, hydrothermal, and bacterial sulphate reduction sources. The description discusses specific geological formations like McArthur River and Mount Isa in Australia's Northern Territory. It was last updated on 2026-03-25.

Use Cases

• Modeling biogenic sulphide generation based on descriptions of sulphate reduction in anoxic marine sediments.
• Comparing hydrothermal and bacterial sulphide formation processes based on the described temperature thresholds (above 200°C vs. below 70°C).
• Studying constraints on fixed sulphide concentrations based on the described availability of reactable metals.

Strengths

• Published by Geoscience Australia Data, a government earth sciences organization.
• Description provides specific geological examples (McArthur River, Mount Isa) and temperature thresholds for processes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided as PDF/HTML documents, which may require extraction for computational analysis.
