Harris Greenstone Belt GIS Dataset: Geological and Geophysical Interpretations

The Harris Greenstone Domain is a late Archean-Proterozoic tectonostratigraphic terrane in the Gawler Craton. Its distribution and structure are based largely on interpretation of aeromagnetics, gravity, and diamond drillcore data. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-06-27.

Use Cases

• Mineral prospectivity mapping based on described komatiite sequences and associated Ni-Cu-PGE sulphide potential.
• Geological modeling based on interpreted aeromagnetic and gravity data mentioned in the description.
• Stratigraphic analysis based on the described lithological sequence including ultramafic-mafic extrusives, metasediments, and felsic intrusives.
• Tectonic studies based on the domain's boundaries defined by the Yerda Shear Zone and Wilgena Domain.

Strengths

• Covers a specific, named geological domain (Harris Greenstone Domain) with detailed lithological descriptions.
• Integrates multiple data sources including aeromagnetics, gravity, and diamond drillcore for structural interpretation.
• Identifies a specific mineral potential (Ni-Cu-PGE sulphide and lode-Au) for the Lake Harris Komatiite.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The greenstone sequence is described as poorly exposed and covered by thin Quaternary and Eocene deposits.
