Harris Greenstone Belt: Geological and Geophysical Data for Mineral Exploration

Geospatial data for the Harris Greenstone Belt, a late Archean-Proterozoic terrane in the Gawler Craton of Australia. The dataset describes lithological units, magnetic features, and geological structures, with interpretations based on aeromagnetics, gravity, and diamond drillcore. It is hosted by the Australian Ocean Data Network and was last updated on 2026-04-10.

Use Cases

• Identify prospective areas for nickel-copper-PGE sulphide deposits based on komatiite occurrences.
• Model subsurface geological structures based on interpreted aeromagnetic and gravity data.
• Analyze the distribution and metamorphic history of greenstone belt rock types like komatiite and banded iron formation.
• Map lithological zone boundaries and shear zones for regional tectonic studies.

Strengths

• Focuses on a specific, prospective geological terrane containing komatiite, a key host rock for certain mineral deposits.
• Integrates multiple data sources including aeromagnetics, gravity, and diamond drillcore for interpretation.
• Describes a clear temporal context, referencing the Sleafordian Orogeny at ~2440 Ma.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes the belt is poorly exposed, suggesting data is largely interpretive.
