Description
The Harris Greenstone Domain is a late Archean-Proterozoic terrane in the Gawler Craton of Australia. This dataset is a GeoPDF map produced by the Australian Ocean Data Network, last updated in 2026, which layers geological interpretations of aeromagnetic, gravity, and drillcore data. The map details lithological zones, magnetic features, and prospective mineral systems like Ni-Cu-PGE sulphide and lode-Au.
Use Cases
Analyze magnetic anomaly patterns for structural interpretation based on the described east-northeast trending sinuous magnetic high features.
Assess mineral prospectivity for Ni-Cu-PGE sulphide deposits based on the described komatiite sequence and Lake Harris Komatiite.
Study lithological boundaries and terrane architecture based on the described Yerda Shear Zone and Wilgena Domain boundary.
Integrate geological map layers with other geographic data for regional analysis based on the GeoPDF's georeferenced coordinate system.
Strengths
Map is georeferenced, allowing coordinate location and distance retrieval automatically.
Data layers can be turned on and off, enabling customised views similar to GIS tools.
Interpretation is based on multiple data sources: aeromagnetics, gravity, and diamond drillcore.
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 the specific region of the Gawler Craton.
Provenance
Source
Australian Ocean Data Network
Collection Method
Interpretation of aeromagnetics, gravity, and diamond drillcore.
