Harris Greenstone Domain GeoPDF: Geological Map of the Gawler Craton

Geoscience Australia Data provides a GeoPDF map of the Harris Greenstone Domain, a late Archean-Proterozoic terrane in the Gawler Craton. The map depicts lithological units, magnetic features, and structural interpretations based on aeromagnetic, gravity, and drillcore data. It was last updated on 2026-05-14.

Use Cases

• Analyze geological structure and lithological boundaries based on interpreted aeromagnetic and gravity data.
• Identify prospective areas for Ni-Cu-PGE sulphide and lode-Au mineralization based on komatiite distribution.
• Plan exploration campaigns by visualizing the subsurface structure of the greenstone belt beneath thin cover.
• Conduct spatial analysis using georeferenced layers for coordinate and distance retrieval.

Strengths

• Map is georeferenced, allowing coordinate and distance retrieval compatible with other geographic data.
• Data layers can be toggled on and off for customized viewing, similar to GIS tools.
• Interpretation is based on multiple data sources including aeromagnetics, gravity, and diamond drillcore.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
