Harris Greenstone Domain: Geological Map of the Gawler Craton as GeoPDF

The Gawler Craton in central Australia contains the late Archean-Proterozoic Harris Greenstone Domain. This GeoPDF map, produced by Geoscience Australia, visualizes the domain's lithology and structure based on aeromagnetic, gravity, and drillcore interpretation. The map is georeferenced, allowing coordinate and distance retrieval, and was last updated on 2026-04-20.

Use Cases

• Identify potential Ni-Cu-PGE and gold mineralizing systems based on the described komatiite sequences.
• Analyze regional geological structure based on interpreted aeromagnetic and gravity data.
• Conduct geological mapping and cross-section planning based on the defined lithological zones and shear boundaries.
• Study Archean-Proterozoic tectonostratigraphic terrains based on the described rock assemblages and metamorphic history.

Strengths

• Map is georeferenced, enabling compatibility with other geographic data and automatic coordinate retrieval.
• Description provides specific geological context, including named formations, rock types, and tectonic events like the Sleafordian Orogeny at ~2440 Ma.
• Data layers can be toggled on and off within the GeoPDF, similar to GIS tools.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• The primary data format is a GeoPDF, which may require specific plugins or conversion for use in standard GIS software.
