Harris Greenstone Domain Geological Map As GeoPDF

Geological map of the Harris Greenstone Domain, a late Archean-Proterozoic terrane within Australia's Gawler Craton. The map is a georeferenced GeoPDF produced by the Australian Ocean Data Network, last updated in April 2026. It visualizes lithological units, magnetic features, and structural boundaries interpreted from aeromagnetic and gravity data.

Use Cases

• Identify prospective areas for Ni-Cu-PGE and gold mineralization by analyzing the distribution of the Lake Harris Komatiite layer.
• Correlate lithological zone boundaries, such as the Yerda Shear Zone, with magnetic high and low features from the geophysical interpretation.
• Model subsurface structure by toggling layers for Quaternary sand cover and Eocene fluvial deposits against the interpreted greenstone sequence.
• Extract coordinate locations and distances for field mapping and drill planning using the georeferenced GeoPDF capabilities.

Strengths

• Map is georeferenced for compatibility with other geographic data systems.
• Includes interpreted data from multiple sources: aeromagnetics, gravity, and diamond drillcore.
• Produced by a national data organization, the Australian Ocean Data Network.

Limitations

• Underlying sample data, row counts, and specific columnar data are unavailable.
• Geological interpretation is based largely on geophysics due to poor surface exposure.
• File format is PDF/GeoPDF, not a structured data format like CSV or shapefile.
