Geological and Borehole Data for Southwestern Victoria and South Australia

A compilation of geological and borehole data from southwestern Victoria and contiguous South Australia, focusing on the Portland-Nelson-Mt Gambier area. The Australian Ocean Data Network compiled this report, which includes a geological sketch map and tabulated bore-hole and well records. The report was last updated on 2026-05-05.

Use Cases

• Analyze subsurface geological structure based on compiled borehole records.
• Study stratigraphy and geological history of Tertiary to Recent formations.
• Plan geophysical surveys to investigate deep structural features.
• Map regional geology where surface exposure of underlying rocks is poor.

Strengths

• Compilation includes records from the principal bores in the area.
• Report incorporates a geological sketch map.
• Data covers a large territory in southwestern Victoria and southeastern South Australia.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
