Harris Greenstone Domain GeoPDF: Geological Map of the Gawler Craton

A GeoPDF map of the Harris Greenstone Domain, a late Archean-Proterozoic terrane in central Australia's Gawler Craton. The map, produced by the Australian Ocean Data Network, layers geological features like komatiite belts and magnetic structures, allowing for interactive analysis similar to GIS tools. It is based on interpretations of aeromagnetics, gravity data, and diamond drillcore.

Use Cases

• Identify potential Ni-Cu-PGE and gold mineralizing systems based on the described komatiite sequences.
• Analyze subsurface geological structure based on interpreted aeromagnetic and gravity features.
• Study the tectonostratigraphic boundaries and lithological zones mentioned, such as the Yerda Shear Zone.
• Correlate geological units like the Hiltaba Suite Granite and Gawler Range Volcanics across the region.

Strengths

• Map is georeferenced, allowing coordinate and distance retrieval compatible with other geographic data.
• GeoPDF format provides interactive layers that can be toggled on and off for customized analysis.
• Description provides specific geological context, including rock types, formation names, and tectonic events.

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.
