Victoria Subsurface Geology from Geophysical Surveys at 1:250,000 Scale

Interpreted geological data from the Geological Survey of Victoria maps deeply buried geological units using combined airborne magnetic, radiometric, and gravity surveys. Recent 1:250,000 scale mapping supersedes older 1:100,000 data in specific areas like St Arnaud, Bendigo, and the Grampians. This dataset is part of a collection that includes geological polygons, boundaries, and structural lines.

Use Cases

• Modeling subsurface geology based on combined magnetic, radiometric, and gravity interpretations.
• Identifying deeply buried geological units for mineral exploration.
• Updating regional geological maps by superseding older 1:100,000 scale data with newer 1:250,000 interpretations.
• Analyzing geological structure and boundaries in areas like St Arnaud, Bendigo, and the Grampians.

Strengths

• Data is provided in multiple geospatial formats including SHP, GDB, and DWG.
• Interpretations combine three geophysical survey types: airborne magnetic, radiometric, and gravity.
• Specific map sheets where newer 1:250,000 data supersedes older 1:100,000 data are listed.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
