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

The Harris Greenstone Domain is a late Archean-Proterozoic terrane in the centre of the Gawler Craton in Australia. This map, produced as a GeoPDF by the Australian Ocean Data Network, visualizes the domain's structure based on interpretation of aeromagnetics, gravity, and diamond drillcore. Layers can be toggled for customized views, and the map is georeferenced for compatibility with other geographic data.

Use Cases

• Identify potential Ni-Cu-PGE sulphide and lode-Au mineralizing systems based on the described komatiite sequences.
• Analyze the subsurface structure of greenstone belts based on interpreted aeromagnetic and gravity data.
• Study the lithological boundaries and tectonic history of the Archean-Proterozoic terrane described.
• Plan geological field work by visualizing the distribution of rock types and cover deposits mentioned.

Strengths

• Map is georeferenced, allowing coordinate location and distance retrieval automatically.
• GeoPDF format supports layer toggling for customized data views similar to GIS tools.
• Description provides specific geological context including named rock formations, tectonic boundaries, and metamorphic 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.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a specific Australian region.
