Harris Greenstone Belt Aeromagnetic And Geological Data

Geospatial data describes the Harris Greenstone Belt, a late Archean-Proterozoic terrane in the Gawler Craton. It includes interpreted distributions of rock types like komatiite, basalt, and banded iron formation. The dataset was published by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Identify potential Ni-Cu-PGE sulphide mineralisation by analyzing spatial correlations between the Lake Harris Komatiite unit and magnetic high features.
• Model the subsurface structure of the greenstone belt by interpreting the distribution of east-northeast trending sinuous magnetic highs flanked by magnetic lows.
• Assess geological boundaries, such as the Yerda Shear Zone to the south, using integrated aeromagnetic, gravity, and drillcore data.
• Map lithological zones and rock type distributions, including komatiite, tholeiitic basalt, and banded iron formation, based on geophysical interpretation.

Strengths

• Interpretation based on multiple data sources including aeromagnetics, gravity, and diamond drillcore
• Focuses on a specific, well-defined geological terrane with distinct lithological and structural boundaries

Limitations

• Rock types and structure are largely interpreted, not directly observed, due to poor surface exposure
• The prospective greenstone sequence is covered by thin (<50 m) Quaternary and Eocene deposits, obscuring direct measurement
• Specific quantitative metrics like row count, column count, and spatial resolution are unknown
